+Each REST client is a JavaScript class, which provides functions individually mapped to each endpoint available in the exchange's API offering.
 
 The following table shows all methods available in each REST client, whether the method requires authentication (automatically handled if API keys are provided), as well as the exact endpoint each method is connected to.
 
-This can be used to easily find which method to call, once you have [found which endpoint you're looking to use](https://github.com/tiagosiebler/awesome-crypto-examples/wiki/How-to-find-SDK-functions-that-match-API-docs-endpoint).

+
+> [!TIP]
+> Read this guide in tutorial format on the Siebly website: [Gate JavaScript REST API and WebSocket Tutorial](https://siebly.io/sdk/gate/javascript/tutorial)
+
+<!-- siebly:website-omit:end -->
+
+This tutorial uses [`gateio-api`](https://www.npmjs.com/package/gateio-api), Siebly's Node.js, JavaScript, and TypeScript SDK for Gate.com. It covers public and private REST API calls, Spot and Futures TestNet orders, live WebSocket streams, WebSocket API commands, API hosts, and proxies.
+
+The SDK handles REST API request signing, private WebSocket authentication, product-specific WebSocket routing, heartbeats, reconnects, resubscriptions, and WebSocket API response matching. Request and response types are included for TypeScript users.

+
+## Why use `gateio-api`?
+
+The JavaScript SDK handles all the complexities of integrating with Gate's REST APIs & WebSockets, so you can focus on your system without wasting excessive time on plumbing.
+
+Private Gate REST API requests require a timestamp and HMAC-SHA512 signature. Private WebSocket subscriptions require authentication, and each product family has its own WebSocket connection. A Spot subscription cannot be sent through a USDT perpetual Futures connection.
+
+`gateio-api` handles those mechanics and gives each job a focused client:
+
+| Client               | Use it for                                                   |
+| -------------------- | ------------------------------------------------------------ |
+| `RestClient`         | Public and private REST API calls across Gate product groups |
+| `WebsocketClient`    | Public and private WebSocket subscriptions                   |
+| `WebsocketAPIClient` | Promise-based Spot and Futures order commands over WebSocket |
+
+`WebsocketClient` also handles heartbeats, reconnects, cached subscriptions, and resubscription. `WebsocketAPIClient` adds login, request IDs, response matching, and promise resolution.
+
+## Install the SDK
+
+```bash
+npm install gateio-api
+```
+
+The package includes CommonJS, ESM, and TypeScript declarations. Every example below is plain JavaScript using ESM imports.
+
+## Create Gate API keys
+
+Public market data does not require credentials. Private REST API calls, private streams, and WebSocket API commands require an API key and secret.
+
+Create and manage keys from the [Gate API key page](https://www.gate.com/myaccount/api_key_manage). Start with the least access your application needs:
+
+- Use a read-only key while building account views and recovery code.
+- Enable Spot read-write access only for Spot order workflows.
+- Enable perpetual-contract read-write access only for Futures order workflows.
+- Add an IP whitelist when your outbound IP is stable.
+- Keep live and TestNet credentials separate.
+- Allow a few minutes for API key and permission changes to take effect.
+- Do not enable withdrawal permission for anything in this tutorial.
+
+Set these live credential names in your shell, secret manager, or deployment environment:
+
+- `GATE_API_KEY`
+- `GATE_API_SECRET`
+
+Use separate names for TestNet:
+
+- `GATE_TESTNET_API_KEY`
+- `GATE_TESTNET_API_SECRET`
+- `GATE_PLACE_TESTNET_ORDER=true`
+
+The order examples check `GATE_PLACE_TESTNET_ORDER` before sending an order. Do not log API keys or secrets, and never put them in browser code.
+
+## Gate products and request vocabulary
+
+Several short fields determine where a request goes and what its values mean:
+
+| Field           | Example                        | Meaning                                                                                            |
+| --------------- | ------------------------------ | -------------------------------------------------------------------------------------------------- |
+| `currency_pair` | `BTC_USDT`                     | A Spot or margin market                                                                            |
+| `account`       | `spot`                         | The account used by a Spot order or query                                                          |
+| `settle`        | `usdt`                         | The settlement currency for a Futures or Delivery REST API request                                 |
+| `contract`      | `BTC_USDT`                     | The exact Futures, Delivery, or Options contract                                                   |
+| `size`          | `1` or `-1`                    | Futures contract count, not a BTC or USDT amount                                                   |
+| `text`          | `t-my-order-123`               | Your [custom order ID](https://siebly.io/reference/glossary#custom-order-id)                       |
+| `wsKey`         | `WS_KEY_MAP.perpFuturesUSDTV4` | The [WebSocket key](https://siebly.io/reference/glossary#ws-key) that selects a product connection |
+
+For Spot orders, `account` can be `spot`, `margin`, `cross_margin`, or `unified`, depending on the account and endpoint. This tutorial uses `spot`.
+
+For USDT perpetual Futures, use `settle: 'usdt'` and a contract such as `BTC_USDT`. The `size` is a number of contracts. In one-way mode, a positive size buys and a negative size sells. The contract's `quanto_multiplier` tells you how much underlying currency one contract represents.
+
+Keep these routing values visible in code and logs. They are part of the request, not interchangeable labels.

+
+## Start building: first calls and streams
+
+Run each example on its own. Start with public data, then add authenticated account state and live streams.
+
+### 1. Make public REST API calls
+
+Public calls need no API key. Gate response bodies are endpoint-specific: server time and order books are objects, tickers are arrays, and candles are tuple arrays.
+
+<!-- siebly:snippet id="public-rest" -->
+
+```javascript
+import { RestClient } from 'gateio-api';
+
+const client = new RestClient();
+
+async function main() {
+  try {
+    const time = await client.getServerTime();
+    console.log('Server time:', time.server_time);
+  } catch (error) {
+    console.error('Server time request failed:', error);
+  }
+
+  try {
+    const pair = await client.getSpotCurrencyPair({
+      currency_pair: 'BTC_USDT',
+    });
+    console.log('BTC_USDT metadata:', pair);
+  } catch (error) {
+    console.error('Currency pair request failed:', error);
+  }
+
+  try {
+    const tickers = await client.getSpotTicker({
+      currency_pair: 'BTC_USDT',
+    });
+    console.log('BTC_USDT ticker:', tickers[0]);
+  } catch (error) {
+    console.error('Ticker request failed:', error);
+  }
+
+  try {
+    const orderBook = await client.getSpotOrderBook({
+      currency_pair: 'BTC_USDT',
+      limit: 5,
+    });
+    console.log('Best bid:', orderBook.bids[0]);
+    console.log('Best ask:', orderBook.asks[0]);
+  } catch (error) {
+    console.error('Order book request failed:', error);
+  }
+
+  try {
+    const candles = await client.getSpotCandles({
+      currency_pair: 'BTC_USDT',
+      interval: '1h',
+      limit: 10,
+    });
+    console.log('Latest candle:', candles[0]);
+  } catch (error) {
+    console.error('Candles request failed:', error);
+  }
+}
+
+main();
+```
+
+The SDK returns the endpoint body directly. There is no shared result wrapper to unwrap.
+
+Each Spot candle is a tuple:
+
+```text
+[
+  timestamp,
+  quoteVolume,
+  close,
+  high,
+  low,
+  open,
+  baseVolume,
+  closed
+]
+```
+
+Use the [SDK endpoint map](./endpointFunctionList.md) or the official endpoint documentation when reading tuple positions and endpoint-specific objects.
+
+### 2. Make private REST API calls
+
+Private calls use the same `RestClient`. Add your key and secret, then call private methods normally. The SDK adds the required timestamp and signature.
+
+<!-- siebly:snippet id="private-rest" -->
+
+```javascript
+import { RestClient } from 'gateio-api';
+
+const client = new RestClient({
+  apiKey: process.env.GATE_API_KEY,
+  apiSecret: process.env.GATE_API_SECRET,
+});
+
+async function main() {
+  try {
+    const balances = await client.getSpotAccounts();
+    console.log('Spot balances:', balances);
+  } catch (error) {
+    console.error('Balance request failed:', error);
+  }
+
+  try {
+    const openOrders = await client.getSpotOpenOrders({
+      account: 'spot',
+    });
+    console.log('Open Spot orders grouped by pair:', openOrders);
+  } catch (error) {
+    console.error('Open-order request failed:', error);
+  }
+
+  try {
+    const recentOrders = await client.getSpotOrders({
+      currency_pair: 'BTC_USDT',
+      status: 'finished',
+      account: 'spot',
+      limit: 20,
+    });
+    console.log('Recent BTC_USDT orders:', recentOrders);
+  } catch (error) {
+    console.error('Order-history request failed:', error);
+  }
+
+  try {
+    const trades = await client.getSpotTradingHistory({
+      currency_pair: 'BTC_USDT',
+      account: 'spot',
+      limit: 20,
+    });
+    console.log('Recent BTC_USDT trades:', trades);
+  } catch (error) {
+    console.error('Trade-history request failed:', error);
+  }
+}
+
+main();
+```
+
+`getSpotAccounts()`, `getSpotOrders()`, and `getSpotTradingHistory()` return arrays. `getSpotOpenOrders()` returns an array whose entries group open orders by currency pair. Other private endpoints return objects or different array shapes, so check the [SDK endpoint map](./endpointFunctionList.md) instead of assuming a common format.
+
+### 3. Subscribe to public WebSocket streams
+
+Every subscription includes both a topic and an explicit `wsKey`. The key tells the SDK which Gate connection should carry the subscription.
+
+<!-- siebly:snippet id="public-websocket" -->
+
+```javascript
+import { WebsocketClient, WS_KEY_MAP } from 'gateio-api';
+
+const ws = new WebsocketClient();
+
+ws.on('response', (response) => {
+  console.log('Subscription response:', response);
+});
+
+ws.on('update', (update) => {
+  console.log('WebSocket update:', update);
+});
+
+ws.on('reconnect', ({ wsKey }) => {
+  console.log('Reconnecting:', wsKey);
+});
+
+ws.on('reconnected', (event) => {
+  console.log('Reconnected:', event.wsKey);
+});
+
+ws.on('exception', (error) => {
+  console.error('WebSocket exception:', error);
+});
+
+try {
+  ws.subscribe(
+    {
+      topic: 'spot.tickers',
+      payload: ['BTC_USDT'],
+    },
+    WS_KEY_MAP.spotV4,
+  );
+} catch (error) {
+  console.error('Spot subscription failed:', error);
+}
+
+try {
+  ws.subscribe(
+    {
+      topic: 'futures.tickers',
+      payload: ['BTC_USDT'],
+    },
+    WS_KEY_MAP.perpFuturesUSDTV4,
+  );
+} catch (error) {
+  console.error('Futures subscription failed:', error);
+}
+
+process.once('SIGINT', () => {
+  ws.closeAll();
+});
+```
+
+Gate sends Spot ticker data as an object in `result`, while a Futures ticker update can contain an array. The SDK adds `wsKey` to each update so one event handler can identify the source connection.
+
+The main WebSocket events are:
+
+| Event           | Meaning                                                       |
+| --------------- | ------------------------------------------------------------- |
+| `open`          | A connection opened for the reported `wsKey`                  |
+| `response`      | Subscription, unsubscription, or request response             |
+| `update`        | Market or account data                                        |
+| `authenticated` | A private connection authenticated successfully               |
+| `reconnect`     | The connection dropped and a reconnect is starting            |
+| `reconnected`   | The connection is open and cached subscriptions were restored |
+| `close`         | A connection closed for the reported `wsKey`                  |
+| `exception`     | The client or connection reported an error                    |
+
+A successful `response` event confirms the [subscription acknowledgement](https://siebly.io/reference/glossary#subscription-acknowledgement). It does not mean that a market update has arrived yet.
+
+### 4. Subscribe to private Spot streams
+
+Private streams use the same client with credentials. This example follows Spot balances, orders, and user trades.
+
+<!-- siebly:snippet id="private-websocket" -->
+
+```javascript
+import { WebsocketClient, WS_KEY_MAP } from 'gateio-api';
+
+const ws = new WebsocketClient({
+  apiKey: process.env.GATE_API_KEY,
+  apiSecret: process.env.GATE_API_SECRET,
+});
+
+ws.on('authenticated', ({ wsKey }) => {
+  console.log('Authenticated:', wsKey);
+});
+
+ws.on('response', (response) => {
+  console.log('Subscription response:', response);
+});
+
+ws.on('update', (update) => {
+  console.log('Private Spot update:', update);
+});
+
+ws.on('reconnected', (event) => {
+  console.log('Reconnected:', event.wsKey);
+});
+
+ws.on('exception', (error) => {
+  console.error('WebSocket exception:', error);
+});
+
+try {
+  ws.subscribe(
+    {
+      topic: 'spot.balances',
+    },
+    WS_KEY_MAP.spotV4,
+  );
+} catch (error) {
+  console.error('Balance subscription failed:', error);
+}
+
+try {
+  ws.subscribe(
+    {
+      topic: 'spot.orders',
+      payload: ['BTC_USDT'],
+    },
+    WS_KEY_MAP.spotV4,
+  );
+} catch (error) {
+  console.error('Order subscription failed:', error);
+}
+
+try {
+  ws.subscribe(
+    {
+      topic: 'spot.usertrades',
+      payload: ['BTC_USDT'],
+    },
+    WS_KEY_MAP.spotV4,
+  );
+} catch (error) {
+  console.error('Trade subscription failed:', error);
+}
+
+process.once('SIGINT', () => {
+  ws.closeAll();
+});
+```
+
+Use the `authenticated` event as a connection-level signal. Use private updates as [private stream confirmation](https://siebly.io/reference/glossary#private-stream-confirmation) of account and order changes.
+
+Other private Spot topics include `spot.margin_balances` and `spot.cross_balances`. Check each channel's payload rules before subscribing.
+
+### 5. Subscribe to private Futures streams
+
+Futures private channels use your Gate user ID. Contract-specific channels also include the contract. Retrieve the user ID once from the REST API, then use the payload required by each channel.
+
+```javascript
+import { RestClient, WebsocketClient, WS_KEY_MAP } from 'gateio-api';
+
+const rest = new RestClient({
+  apiKey: process.env.GATE_API_KEY,
+  apiSecret: process.env.GATE_API_SECRET,
+});
+
+const ws = new WebsocketClient({
+  apiKey: process.env.GATE_API_KEY,
+  apiSecret: process.env.GATE_API_SECRET,
+});
+
+ws.on('authenticated', ({ wsKey }) => {
+  console.log('Authenticated:', wsKey);
+});
+
+ws.on('response', (response) => {
+  console.log('Subscription response:', response);
+});
+
+ws.on('update', (update) => {
+  console.log('Private Futures update:', update);
+});
+
+ws.on('exception', (error) => {
+  console.error('WebSocket exception:', error);
+});
+
+async function main() {
+  let account;
+
+  try {
+    account = await rest.getAccountDetail();
+    console.log('Gate user ID:', account.user_id);
+  } catch (error) {
+    console.error('Account detail request failed:', error);
+    return;
+  }
+
+  const userId = String(account.user_id);
+  const payload = [userId, 'BTC_USDT'];
+  const wsKey = WS_KEY_MAP.perpFuturesUSDTV4;
+
+  try {
+    ws.subscribe(
+      {
+        topic: 'futures.orders',
+        payload,
+      },
+      wsKey,
+    );
+  } catch (error) {
+    console.error('Order subscription failed:', error);
+  }
+
+  try {
+    ws.subscribe(
+      {
+        topic: 'futures.usertrades',
+        payload,
+      },
+      wsKey,
+    );
+  } catch (error) {
+    console.error('Trade subscription failed:', error);
+  }
+
+  try {
+    ws.subscribe(
+      {
+        topic: 'futures.balances',
+        payload: [userId],
+      },
+      wsKey,
+    );
+  } catch (error) {
+    console.error('Balance subscription failed:', error);
+  }
+
+  try {
+    ws.subscribe(
+      {
+        topic: 'futures.positions',
+        payload,
+      },
+      wsKey,
+    );
+  } catch (error) {
+    console.error('Position subscription failed:', error);
+  }
+}
+
+process.once('SIGINT', () => {
+  ws.closeAll();
+});
+
+main();
+```
+
+Keep the `wsKey` aligned with the settlement currency and product. USDT perpetual Futures use `WS_KEY_MAP.perpFuturesUSDTV4`; BTC perpetual Futures use `WS_KEY_MAP.perpFuturesBTCV4`.
+
+Gate also provides private Futures channels such as `futures.autoorders`. Use the payload documented for that specific channel.
+
+### 6. Place and cancel a Spot order in TestNet
+
+Gate TestNet uses separate credentials and API hosts. This example:
+
+1. Checks the explicit order opt-in.
+2. Loads current `BTC_USDT` trading rules and the order book.
+3. Calculates an amount that meets the pair's base and quote minimums.
+4. Places a post-only limit buy at the current best bid.
+5. Queries the order and cancels it if it remains open.
+
+The order uses `time_in_force: 'poc'`, Gate's post-only setting. A fast market can move before the request arrives, in which case Gate can reject or finish the order instead of leaving it on the book.
+
+<!-- siebly:snippet id="spot-testnet-rest-order" -->

+  } catch (error) {
+    console.error('Spot order cancellation failed:', error);

+}
+
+main();
+```
+
+The extra amount increment avoids falling just below the quote minimum after decimal rounding. Before using another pair, read its `amount_precision`, `precision`, minimums, maximums, and `trade_status`.
+
+### 7. Place and cancel a USDT perpetual order in TestNet
+
+A Futures `size` is a contract count. It is not an amount of BTC or USDT. This example reads the contract's minimum size and current price, and it only runs when the account is in one-way mode. It does not change account or position settings.

+
+In one-way mode, a positive `size` buys and a negative `size` sells. Dual-side mode uses different position semantics, so handle it in account-specific code after reading the [official Gate API v4 documentation](https://www.gate.com/docs/developers/apiv4/en/).
+
+The contract metadata supplies the size and price rules:
+
+- `order_size_min`: minimum contract count
+- `order_price_round`: permitted price increment
+- `quanto_multiplier`: underlying amount represented by one contract
+- `enable_decimal`: whether fractional contract sizes are supported
+
+Do not derive a Futures order size from Spot precision rules.
+
+### 8. Send a Spot order through the WebSocket API
+
+`WebsocketAPIClient` turns Gate WebSocket API commands into promises. It connects and authenticates automatically on the first private command, adds a request ID, matches the response, and resolves the promise.
+
+This TestNet example uses the REST API only to read current market rules and the order book. The order, query, and cancellation use the WebSocket API.

+
+Successful commands have `header.status === '200'`, and the endpoint result is in `data.result`. The SDK rejects a command promise when Gate returns a non-success status.
+
+An accepted command is not proof that an order later filled, remained open, or was cancelled. Treat the response as [pending confirmation](https://siebly.io/reference/glossary#pending-confirmation), then confirm the final state through the private order stream or a REST API query.
+
+<!-- siebly:section id="rest-api" -->
+
+## Work with the Gate REST API
+
+`RestClient` covers Gate's product groups through named methods. Public methods work without credentials. Private methods use the API key and secret passed to the client.
+
+### Understand response shapes
+
+The client resolves to the endpoint's response body:
+
+```javascript
+import { RestClient } from 'gateio-api';
+
+const client = new RestClient();
+
+async function main() {
+  try {
+    const result = await client.getSpotOrderBook({
+      currency_pair: 'BTC_USDT',
+    });
+    console.log(result);
+  } catch (error) {
+    console.error('Order book request failed:', error);
+  }
+}
+
+main();
+```
+
+There is no shared response envelope. Check the [SDK endpoint map](./endpointFunctionList.md) before deciding how to handle `result`.
+
+| Method                  | Response shape                             |
+| ----------------------- | ------------------------------------------ |
+| `getServerTime()`       | Object with `server_time`                  |
+| `getSpotCurrencyPair()` | Currency-pair object                       |
+| `getSpotTicker()`       | Array of ticker objects                    |
+| `getSpotOrderBook()`    | Object with tuple-array `bids` and `asks`  |
+| `getSpotCandles()`      | Array of candle tuples                     |
+| `getFuturesContract()`  | Contract object                            |
+| `getFuturesTickers()`   | Array of ticker objects                    |
+| `getFuturesOrderBook()` | Object with `{ p, s }` bid and ask entries |
+| `getFuturesAccount()`   | Account object                             |
+| `getFuturesPositions()` | Array of position objects                  |
+
+Prices and quantities are commonly returned as strings. Keep them as strings while passing them between Gate API methods. Convert them deliberately when doing calculations, and round the result back to the product's required precision.
+
+### Read account state
+
+An authenticated integration usually needs these views:
+
+| State               | Spot method               | USDT perpetual method                                      |
+| ------------------- | ------------------------- | ---------------------------------------------------------- |
+| Balances or account | `getSpotAccounts()`       | `getFuturesAccount({ settle: 'usdt' })`                    |
+| Positions           | Not applicable            | `getFuturesPositions({ settle: 'usdt' })`                  |
+| Open orders         | `getSpotOpenOrders()`     | `getFuturesOrders({ settle: 'usdt', status: 'open' })`     |
+| Recent orders       | `getSpotOrders()`         | `getFuturesOrders({ settle: 'usdt', status: 'finished' })` |
+| Trades              | `getSpotTradingHistory()` | `getFuturesTradingHistory({ settle: 'usdt' })`             |
+
+These REST API views form a reliable [account state](https://siebly.io/reference/glossary#accountstate) baseline before stream updates are applied.
+
+### Explore other Gate product groups
+
+The same `RestClient` also covers the following APIs. Start with read methods and check account eligibility, permissions, and product-specific rules before using any write method.

+<!-- siebly:section id="websocket-streams" -->
+
+## Build with WebSocket streams
+
+Use `WebsocketClient` for ongoing market and account updates. A subscription request has two independent parts:
+
+- `topic` and `payload` select the Gate channel and its data.
+- `wsKey` selects the product connection that carries the subscription.
+
+One `subscribe()` call can contain several topics when they share the same `wsKey`. Use separate calls for topics on different product connections.
+
+### Choose the correct WebSocket key
+
+| Product connection     | SDK key                            |
+| ---------------------- | ---------------------------------- |
+| Spot                   | `WS_KEY_MAP.spotV4`                |
+| USDT perpetual Futures | `WS_KEY_MAP.perpFuturesUSDTV4`     |
+| BTC perpetual Futures  | `WS_KEY_MAP.perpFuturesBTCV4`      |
+| USDT Delivery          | `WS_KEY_MAP.deliveryFuturesUSDTV4` |
+| BTC Delivery           | `WS_KEY_MAP.deliveryFuturesBTCV4`  |
+| Options                | `WS_KEY_MAP.optionsV4`             |
+| Announcements          | `WS_KEY_MAP.announcementsV4`       |
+
+Do not infer the connection from a symbol alone. `BTC_USDT` can appear in more than one product family.
+
+Useful public topics include:
+
+| Product | Starting topics                                                                                                |
+| ------- | -------------------------------------------------------------------------------------------------------------- |
+| Spot    | `spot.tickers`, `spot.trades`, `spot.order_book`, `spot.order_book_update`, `spot.candlesticks`                |
+| Futures | `futures.tickers`, `futures.trades`, `futures.order_book`, `futures.order_book_update`, `futures.candlesticks` |
+| Options | `options.tickers`, `options.trades`, `options.order_book`, `options.ul_tickers`                                |
+
+### Treat responses and updates differently
+
+The `response` event tells you whether Gate accepted a subscribe, unsubscribe, or request message. Check its `error` and `result`.
+
+The `update` event carries channel data. Inspect `channel`, `event`, `result`, and the SDK-added `wsKey` before updating local state. A subscription response and a data update can have different result shapes.
+
+### Recover after a reconnect
+
+The SDK reconnects and restores cached subscriptions. A stream gap can still hide balance, order, trade, or position changes. Reload the affected state from the REST API after `reconnected`.
+
+This Spot example reloads balances, open orders, and recent trades in sequence:
+
+```javascript
+import { RestClient, WebsocketClient, WS_KEY_MAP } from 'gateio-api';
+
+const rest = new RestClient({
+  apiKey: process.env.GATE_API_KEY,
+  apiSecret: process.env.GATE_API_SECRET,
+});
+
+const ws = new WebsocketClient({
+  apiKey: process.env.GATE_API_KEY,
+  apiSecret: process.env.GATE_API_SECRET,
+});
+
+let recoveryRunning = false;
+let spotState;
+
+async function recoverSpotState() {
+  if (recoveryRunning) {
+    return;
+  }
+
+  recoveryRunning = true;
+
+  try {
+    let balances;
+
+    try {
+      balances = await rest.getSpotAccounts();
+    } catch (error) {
+      console.error('Balance recovery failed:', error);
+      return;
+    }
+
+    let openOrders;
+
+    try {
+      openOrders = await rest.getSpotOpenOrders({
+        account: 'spot',
+      });
+    } catch (error) {
+      console.error('Open-order recovery failed:', error);
+      return;
+    }
+
+    let trades;
+
+    try {
+      trades = await rest.getSpotTradingHistory({
+        currency_pair: 'BTC_USDT',
+        account: 'spot',
+        limit: 100,
+      });
+    } catch (error) {
+      console.error('Trade recovery failed:', error);
+      return;
+    }
+
+    spotState = {
+      balances,
+      openOrders,
+      trades,
+      recoveredAt: Date.now(),
+    };
+
+    console.log('Recovered Spot state:', spotState);
+  } finally {
+    recoveryRunning = false;
+  }
+}
+
+ws.on('reconnected', async ({ wsKey }) => {
+  if (wsKey !== WS_KEY_MAP.spotV4) {
+    return;
+  }
+
+  await recoverSpotState();
+});
+
+ws.on('update', (update) => {
+  console.log('Private Spot update:', update);
+});
+
+ws.on('exception', (error) => {
+  console.error('WebSocket exception:', error);
+});
+
+try {
+  ws.subscribe(
+    {
+      topic: 'spot.balances',
+    },
+    WS_KEY_MAP.spotV4,
+  );
+} catch (error) {
+  console.error('Balance subscription failed:', error);
+}
+
+try {
+  ws.subscribe(
+    {
+      topic: 'spot.orders',
+      payload: ['BTC_USDT'],
+    },
+    WS_KEY_MAP.spotV4,
+  );
+} catch (error) {
+  console.error('Order subscription failed:', error);
+}
+
+try {
+  ws.subscribe(
+    {
+      topic: 'spot.usertrades',
+      payload: ['BTC_USDT'],
+    },
+    WS_KEY_MAP.spotV4,
+  );
+} catch (error) {
+  console.error('Trade subscription failed:', error);
+}
+
+process.once('SIGINT', () => {
+  ws.closeAll();
+});
+```
+
+This is [REST API hydration](https://siebly.io/reference/glossary#rest-hydration) applied as [scoped recovery](https://siebly.io/reference/glossary#scoped-recovery). The example replaces `spotState` only after all three reads succeed. Reload only the state that may have changed on the affected connection, then reconcile it before trusting new updates.

+For a wider recovery design, see [Exchange State](https://siebly.io/reference/exchange-state) and [Runtime Workflows](https://siebly.io/reference/runtime-workflows).

+
+## Use the Gate WebSocket API
+
+`WebsocketAPIClient` is for request and response commands over WebSocket. It is not the same as a subscription stream.
+
+The client:
+
+1. Opens the selected WebSocket connection.
+2. Authenticates automatically.
+3. Adds a unique request ID.
+4. Sends the command.
+5. Matches Gate's response to the pending promise.
+6. Resolves with `header`, `data.result`, `request_id`, and `wsKey`.
+
+Authentication happens automatically on the first command. `connectWSAPI(wsKey)` is available when an application wants to open and authenticate the connection early. Automatic WebSocket API reauthentication after a reconnect is enabled by default.
+
+Spot methods include:
+
+- `submitNewSpotOrder()`
+- `getSpotOrderStatus()`
+- `getSpotOrders()`
+- `updateSpotOrder()`
+- `cancelSpotOrder()`
+- `cancelSpotOrderById()`
+- `cancelSpotOrderForSymbol()`
+
+Futures methods include:
+
+- `submitNewFuturesOrder()`
+- `submitNewFuturesBatchOrder()`
+- `getFuturesOrderStatus()`
+- `getFuturesOrders()`
+- `updateFuturesOrder()`
+- `cancelFuturesOrder()`
+
+Pass a Futures `wsKey` explicitly. This keeps the settlement connection visible:
+
+```javascript
+import { WebsocketAPIClient, WS_KEY_MAP } from 'gateio-api';
+
+const wsApi = new WebsocketAPIClient({
+  apiKey: process.env.GATE_API_KEY,
+  apiSecret: process.env.GATE_API_SECRET,
+});
+
+async function main() {
+  try {
+    const response = await wsApi.getFuturesOrders(
+      {
+        contract: 'BTC_USDT',
+        status: 'open',
+        limit: 20,
+      },
+      WS_KEY_MAP.perpFuturesUSDTV4,
+    );
+
+    console.log(response.header.status);
+    console.log(response.data.result);
+  } catch (error) {
+    console.error('WebSocket API order request failed:', error);
+  } finally {
+    wsApi.getWSClient().closeAll();
+  }
+}
+
+main();
+```
+
+The response confirms the command outcome. Use private order streams or a REST API query to confirm the resulting exchange state.
+
+<!-- siebly:section id="testnet" -->
+
+## Use Gate TestNet
+
+Gate TestNet is a separate environment with separate credentials. Use it for all order examples while learning the SDK.
+
+| Interface                | Current TestNet host                           |
+| ------------------------ | ---------------------------------------------- |
+| REST API                 | `https://api-testnet.gateapi.io/api/v4`        |
+| Spot WebSocket           | `wss://ws-testnet.gate.com/v4/ws/spot`         |
+| USDT perpetual WebSocket | `wss://ws-testnet.gate.com/v4/ws/futures/usdt` |
+
+Set the REST API host with `baseUrl` and the WebSocket host with `wsUrl`. Prefer explicit hosts for TestNet examples:
+
+- Spot WebSocket TestNet is not wired through `useTestnet: true` in this SDK. The Spot testnet map entry is a stub (`NoTestnetForSpotWebsockets!`), so set `wsUrl` to the Spot TestNet host above.
+- For Futures-only REST TestNet, the SDK also accepts `baseUrlKey: 'futuresTestnet'`, which resolves to `https://fx-api-testnet.gateio.ws/api/v4`. The Global TestNet REST host in the table is the host used by the Spot and Futures order examples in this guide.
+
+```javascript
+import { RestClient, WebsocketClient } from 'gateio-api';
+
+const rest = new RestClient({
+  apiKey: process.env.GATE_TESTNET_API_KEY,
+  apiSecret: process.env.GATE_TESTNET_API_SECRET,
+  baseUrl: 'https://api-testnet.gateapi.io/api/v4',
+});
+
+const spotWs = new WebsocketClient({
+  apiKey: process.env.GATE_TESTNET_API_KEY,
+  apiSecret: process.env.GATE_TESTNET_API_SECRET,
+  wsUrl: 'wss://ws-testnet.gate.com/v4/ws/spot',
+});
+```
+
+Do not send live credentials to TestNet or TestNet credentials to live hosts. TestNet balances, liquidity, and available products can differ from live trading.
+
+Fund the required Spot or Futures TestNet account with test assets before running an order example.
+
+<!-- siebly:section id="api-hosts" -->
+
+## Connect to Global and regional REST API hosts
+
+Use the API host associated with the Gate account and product you are integrating. Credentials and product availability are not interchangeable across account regions.
+
+| Environment or account   | REST API base URL                       | Official reference                                                   |
+| ------------------------ | --------------------------------------- | -------------------------------------------------------------------- |
+| Global live              | `https://api.gateio.ws/api/v4`          | [Global Gate API v4](https://www.gate.com/docs/developers/apiv4/en/) |
+| Global TestNet           | `https://api-testnet.gateapi.io/api/v4` | [Global Gate API v4](https://www.gate.com/docs/developers/apiv4/en/) |
+| Futures live alternative | `https://fx-api.gateio.ws/api/v4`       | [Global Gate API v4](https://www.gate.com/docs/developers/apiv4/en/) |
+| Gate US live             | `https://api.gate.us/api/v4`            | [Gate US API v4](https://us.gate.com/en-us/docs/developers/apiv4/)   |
+| Gate EU live             | `https://api.gateeu.com/api/v4`         | [Gate EU API v4](https://eu.gate.com/docs/developers/apiv4/en/)      |
+
+Global live is the SDK default. Set `baseUrl` for another supported account host:
+
+```javascript
+import { RestClient } from 'gateio-api';
+
+const gateUs = new RestClient({
+  apiKey: process.env.GATE_API_KEY,
+  apiSecret: process.env.GATE_API_SECRET,
+  baseUrl: 'https://api.gate.us/api/v4',
+});
+
+const gateEu = new RestClient({
+  apiKey: process.env.GATE_API_KEY,
+  apiSecret: process.env.GATE_API_SECRET,
+  baseUrl: 'https://api.gateeu.com/api/v4',
+});
+```
+
+Use only the client that matches the account. Regional APIs can expose different products and endpoint sets. Check the regional documentation before calling a method, and use the region's own credentials.
+
+This guide does not assign regional WebSocket URLs. Use a regional WebSocket host only when the official documentation for that account region provides it.
+
+<!-- siebly:section id="proxies" -->
+
+## Use a proxy with the REST API and WebSockets
+
+`gateio-api` accepts standard Node.js agents. Configure the agent in both places when all Gate traffic must use the proxy:
+
+- Pass `httpsAgent` in the second `RestClient` argument and set `proxy: false`.
+- Pass the same agent as `wsOptions.agent` to `WebsocketClient` or `WebsocketAPIClient`.
+
+See [Using proxies with Siebly SDKs](https://siebly.io/blog/using-proxy-with-siebly-sdks) for deployment and troubleshooting guidance.
+
+### HTTP and HTTPS proxy
+
+Install the proxy agent:
+
+```bash
+npm install https-proxy-agent
+```
+
+Set `GATE_PROXY_URL` to an `http://` or `https://` proxy URL. The example does not print the value because it may contain credentials.
+
+```javascript
+import { HttpsProxyAgent } from 'https-proxy-agent';
+import { RestClient, WebsocketClient, WS_KEY_MAP } from 'gateio-api';
+
+async function main() {
+  const proxyUrl = process.env.GATE_PROXY_URL;
+
+  if (!proxyUrl) {
+    console.error('Set GATE_PROXY_URL.');
+    return;
+  }
+
+  const agent = new HttpsProxyAgent(proxyUrl);
+
+  const rest = new RestClient(
+    {},
+    {
+      httpsAgent: agent,
+      proxy: false,
+    },
+  );
+
+  const ws = new WebsocketClient({
+    wsOptions: {
+      agent,
+    },
+  });
+
+  ws.on('open', ({ wsKey }) => {
+    console.log('WebSocket connected through proxy:', wsKey);
+  });
+
+  ws.on('response', (response) => {
+    console.log('Subscription response:', response);
+  });
+
+  ws.on('update', (update) => {
+    console.log('Ticker update through proxy:', update);
+    ws.closeAll();
+  });
+
+  ws.on('exception', () => {
+    console.error('WebSocket proxy connection failed.');
+  });
+
+  try {
+    const time = await rest.getServerTime();
+    console.log('Server time through proxy:', time.server_time);
+  } catch {
+    console.error('REST API proxy request failed.');
+  }
+
+  try {
+    ws.subscribe(
+      {
+        topic: 'spot.tickers',
+        payload: ['BTC_USDT'],
+      },
+      WS_KEY_MAP.spotV4,
+    );
+  } catch {
+    console.error('WebSocket proxy subscription failed.');
+  }
+
+  process.once('SIGINT', () => {
+    ws.closeAll();
+  });
+}
+
+main();
+```
+
+For an authenticated HTTP or HTTPS proxy, include the username and password in `GATE_PROXY_URL`. Percent-encode reserved characters in each credential component.
+
+### SOCKS5 proxy
+
+Install the SOCKS agent:
+
+```bash
+npm install socks-proxy-agent
+```
+
+Set `GATE_SOCKS_PROXY_URL` to a `socks5://` URL:
+
+```javascript
+import { SocksProxyAgent } from 'socks-proxy-agent';
+import { RestClient, WebsocketClient, WS_KEY_MAP } from 'gateio-api';
+
+async function main() {
+  const proxyUrl = process.env.GATE_SOCKS_PROXY_URL;
+
+  if (!proxyUrl) {
+    console.error('Set GATE_SOCKS_PROXY_URL.');
+    return;
+  }
+
+  const agent = new SocksProxyAgent(proxyUrl);
+
+  const rest = new RestClient(
+    {},
+    {
+      httpsAgent: agent,
+      proxy: false,
+    },
+  );
+
+  const ws = new WebsocketClient({
+    wsOptions: {
+      agent,
+    },
+  });
+
+  ws.on('open', ({ wsKey }) => {
+    console.log('WebSocket connected through SOCKS5:', wsKey);
+  });
+
+  ws.on('response', (response) => {
+    console.log('Subscription response:', response);
+  });
+
+  ws.on('update', (update) => {
+    console.log('Ticker update through SOCKS5:', update);
+    ws.closeAll();
+  });
+
+  ws.on('exception', () => {
+    console.error('SOCKS5 WebSocket connection failed.');
+  });
+
+  try {
+    const time = await rest.getServerTime();
+    console.log('Server time through SOCKS5:', time.server_time);
+  } catch {
+    console.error('SOCKS5 REST API request failed.');
+  }
+
+  try {
+    ws.subscribe(
+      {
+        topic: 'spot.tickers',
+        payload: ['BTC_USDT'],
+      },
+      WS_KEY_MAP.spotV4,
+    );
+  } catch {
+    console.error('SOCKS5 WebSocket subscription failed.');
+  }
+
+  process.once('SIGINT', () => {
+    ws.closeAll();
+  });
+}
+
+main();
+```
+
+### Private REST API, stream, and WebSocket API traffic
+
+Use the same agent and credentials for private REST API calls, private subscriptions, and WebSocket API connections:
+
+```javascript
+import { HttpsProxyAgent } from 'https-proxy-agent';
+import {
+  RestClient,
+  WebsocketAPIClient,
+  WebsocketClient,
+  WS_KEY_MAP,
+} from 'gateio-api';
+
+async function main() {
+  const proxyUrl = process.env.GATE_PROXY_URL;
+
+  if (!proxyUrl) {
+    console.error('Set GATE_PROXY_URL.');
+    return;
+  }
+
+  const agent = new HttpsProxyAgent(proxyUrl);
+
+  const rest = new RestClient(
+    {
+      apiKey: process.env.GATE_API_KEY,
+      apiSecret: process.env.GATE_API_SECRET,
+    },
+    {
+      httpsAgent: agent,
+      proxy: false,
+    },
+  );
+
+  const streams = new WebsocketClient({
+    apiKey: process.env.GATE_API_KEY,
+    apiSecret: process.env.GATE_API_SECRET,
+    wsOptions: {
+      agent,
+    },
+  });
+
+  const wsApi = new WebsocketAPIClient({
+    apiKey: process.env.GATE_API_KEY,
+    apiSecret: process.env.GATE_API_SECRET,
+    wsOptions: {
+      agent,
+    },
+  });
+
+  streams.on('authenticated', ({ wsKey }) => {
+    console.log('Private stream authenticated:', wsKey);
+  });
+
+  streams.on('update', (update) => {
+    console.log('Private update through proxy:', update);
+  });
+
+  streams.on('exception', () => {
+    console.error('Private stream proxy connection failed.');
+  });
+
+  try {
+    const balances = await rest.getSpotAccounts();
+    console.log('Spot balances through proxy:', balances);
+  } catch {
+    console.error('Private REST API proxy request failed.');
+  }
+
+  try {
+    streams.subscribe(
+      {
+        topic: 'spot.balances',
+      },
+      WS_KEY_MAP.spotV4,
+    );
+  } catch {
+    console.error('Private stream subscription failed.');
+  }
+
+  try {
+    await wsApi.getWSClient().connectWSAPI(WS_KEY_MAP.spotV4);
+    console.log('WebSocket API authenticated through proxy.');
+  } catch {
+    console.error('WebSocket API proxy connection failed.');
+  }
+
+  process.once('SIGINT', () => {
+    streams.closeAll();
+    wsApi.getWSClient().closeAll();
+  });
+}
+
+main();
+```
+
+To combine a proxy with TestNet or a regional API, keep `baseUrl` or `wsUrl` in the first client argument and the agent in the same positions shown above.
+
+The proxy's egress IP is the address Gate sees. Add that address to the API key whitelist when whitelisting is enabled. Use a stable proxy endpoint, monitor its latency, and never use a proxy to bypass account or regional restrictions.
+
+A proxy changes the network path, not request signing, account eligibility, or regional product access. Test public REST API and WebSocket traffic first. Treat HTTP 407 responses, TLS failures, and repeated reconnects as network faults. The SDK does not rotate proxy endpoints.
+
+<!-- siebly:section id="production" -->
+
+## Production checklist
+
+### Keep request time accurate
+
+Gate private requests and WebSocket authentication depend on timestamp checks. The gap between request time and server time must not exceed 60 seconds.
+
+Synchronize the host clock with NTP. Use `getServerTime()` for diagnosis, but fix the system clock rather than adding a permanent application offset for a drifting machine.
+
+### Respect rate limits
+
+Rate limits vary by product and endpoint. Read the current [Gate API rate-limit documentation](https://www.gate.com/docs/developers/apiv4/en/#frequency-limit-rule) and monitor rejection labels.
+
+Retry temporary network failures and rate-limit responses with bounded exponential backoff and jitter. Do not blindly retry an order command after an ambiguous timeout. First reconcile by the order's `text` value or query current order state.
+
+### Use custom order IDs
+
+Set a unique `text` value beginning with `t-` on each application-owned order. Store it with your local request record. This gives retries, restarts, stream updates, and REST API recovery a common identifier.
+
+### Apply product metadata
+
+Before placing an order:
+
+- Check that the pair or contract is tradable.
+- Apply minimum and maximum amounts.
+- Round prices and quantities to the permitted increments.
+- Treat Futures `size` as a contract count.
+- Read `quanto_multiplier` before translating contract size into underlying exposure.
+- Keep one-way, dual-side, and split position modes explicit.
+
+Refresh metadata regularly and when Gate rejects an order for a precision or size rule.
+
+### Confirm final state
+
+A REST API response or WebSocket API response can arrive before later fills, cancellations, or amendments. Record the command response, then confirm final state through private streams or a REST API query.
+
+After a reconnect, restore the affected [exchange state](https://siebly.io/reference/exchange-state) before resuming state-dependent actions.
+
+### Scope credentials and network access
+
+- Use separate keys for live and TestNet.
+- Grant only the product permissions the process needs.
+- Use read-only keys for monitoring services.
+- Do not grant withdrawal permission.
+- Add IP whitelists when egress addresses are stable.
+- Keep secrets in a server-side secret manager or deployment environment.
+- Monitor proxy availability and egress IP changes.
+
+### Shut down connections
+
+Call `closeAll()` on each WebSocket client when the process is ending. An unsubscribe request is unnecessary when the connection is about to close.
+
+## FAQ
+
+### Does `gateio-api` work with plain JavaScript?
+
+Yes. Every example in this guide is plain JavaScript. The examples use ESM imports, so save them as `.mjs` files or set `"type": "module"` in `package.json`. The package also includes a CommonJS build and TypeScript declarations.
+
+### Which client should I use?
+
+Use `RestClient` for public and private REST API calls, `WebsocketClient` for ongoing subscriptions, and `WebsocketAPIClient` for awaitable Spot and Futures commands over WebSocket.
+
+### Do public Gate API calls need credentials?
+
+No. Public market data works without an API key. Account data, private streams, and order commands require credentials with the relevant product permission.
+
+### Why did a REST API call return an object when another returned an array?
+
+Gate response bodies are endpoint-specific. The SDK returns the endpoint body directly. Check the [endpoint map](./endpointFunctionList.md) before reading the result.
+
+### Why does `getSpotTicker()` return an array for one pair?
+
+That is Gate's endpoint response shape. Read the first entry after checking that the array is not empty.
+
+### How are Spot candles structured?
+
+Spot candles are tuple arrays containing timestamp, quote volume, close, high, low, open, base volume, and a closed-window flag in that order.
+
+### Why does Gate use `BTC_USDT`?
+
+Gate uses underscore-separated currency pairs and contract names. Pass the exact identifier returned by the relevant market or contract metadata endpoint.
+
+### What do `account` and `settle` change?
+
+`account` selects the account used by a Spot order or query. `settle` selects the settlement currency and REST API path for Futures or Delivery requests.
+
+### What is the `text` order field?
+
+`text` is Gate's custom order ID field. Use a unique value beginning with `t-` to reconcile requests, stream updates, and order queries.
+
+### Why am I not receiving WebSocket updates?
+
+Check the topic payload, `wsKey`, API host, credentials, and permissions. Then inspect `response`, `authenticated`, and `exception` events. A successful subscription response confirms registration, but an update only arrives when the subscribed data changes.
+
+### Which `WS_KEY_MAP` value should I use?
+
+Choose the key for the exact product connection. For example, Spot uses `spotV4` and USDT perpetual Futures uses `perpFuturesUSDTV4`.
+
+### Why do private Futures topics use my Gate user ID?
+
+It is part of the payload required by those channels. Retrieve it with `getAccountDetail()` instead of hardcoding it.
+
+### What is the difference between a stream and the WebSocket API?
+
+Streams push subscribed market or account updates. The WebSocket API sends a command and resolves a promise with Gate's matching response.
+
+### Does a successful WebSocket API response mean the order filled?
+
+No. It confirms the command result. Confirm later order and fill state through private streams or a REST API query.
+
+### Why was a post-only order rejected or immediately finished?
+
+The best bid or ask can move between the order-book request and order placement. Gate will not let a post-only order take liquidity. Read the returned status and `finish_as`, then decide whether to refresh the book and submit a new order with a new `text`.
+
+### Why does a Futures order size look too small?
+
+Futures `size` is the number of contracts. Use `quanto_multiplier` to find the underlying amount represented by one contract.
+
+### Can live credentials be used in TestNet?
+
+No. TestNet and live trading use separate API keys and balances. Use the current TestNet `baseUrl` or `wsUrl` with TestNet credentials.
+
+### Can I use Gate US or Gate EU with the SDK?
+
+Yes, for endpoints available to that account region. Set the documented regional `baseUrl`, use credentials from the same region, and check its official API documentation for product coverage.
+
+### Can REST API and WebSocket traffic use the same proxy?
+
+Yes. Create one compatible agent, pass it as `httpsAgent` to `RestClient`, and pass it as `wsOptions.agent` to the WebSocket clients.
+
+### Does a proxy change signing or account eligibility?
+
+No. The SDK signs the same requests through the proxy. The Gate account, API host, product permissions, and regional availability still apply.
+
+### What causes `INVALID_SIGNATURE` or `REQUEST_EXPIRED`?
+
+Common causes are a drifting system clock, the wrong API secret, credentials from another environment, or an API request reaching the wrong host. Verify the clock, credential source, and API host without logging the secret.
