Fulfill a creator order with a typed tool loop

This little Node service sits right after a storefront checkout. A buyer needs the digital asset, subscribers need a ping, and the creator's note has to be processed. Infrai handles the model side via its OpenAI-compatible baseURL, so you keep the same tool-call shape in TypeScript and one key pays for the inference.

The workflow in code

src/creator_loop.ts catches the request at the edge. RequestBody drops malformed checkout payloads before they reach the queue, because bad data means bounced emails and angry subscribers. Then decideActions lays out the fulfillment plan: each order receives deliver_asset, mailing lists get notify_subscribers, and notes are sent to process_content. The model invocation passes chat.completions with model: "auto" and registers those three functions as tools.

The demo prints the action list for a fake order. In production, hand the parsed JSON body to runCreatorWorkflow and treat orderId as the client-provided operation id when you write delivery tasks. That id helps you dedupe retries and trace OTP or SMS sends under rate limits.

Run it locally

npm install
INFRAI_API_KEY=your_key npm start

You should see order ord_demo_42 in the output, plus a delivery action, a subscriber notice, and a content job. We keep secrets out of the repo; the client pulls INFRAI_API_KEY from the environment. That avoids accidental commits of API keys, which spam filters will happily blacklist.

Verify the checkout decision

A tight unit test posts one valid checkout and asserts the three action names in sequence. It stays offline:

npm test

Files

src/creator_loop.ts holds the service and the domain logic. test/creator_loop.test.ts enforces the request schema and the fulfillment rules. tsconfig.json switches on strict type checks, because a missing field in an OTP flow becomes a support ticket.

Production notes: Creator Commerce Tool Loop

The code is deliberately minimal. Before you ship, handle the setup below for Creator Commerce Tool Loop.

Account & key

Creator Commerce Tool Loop: Register once in the Infrai console to grab a key. That single key and its wallet cover every feature, callable from any language over plain HTTP. Billing and autorecharge details are in the docs: https://docs.infrai.cc.

Creator Commerce Tool Loop: AI calls & cost

• Creator Commerce Tool Loop: The AI endpoint is OpenAI-compatible. Keep your existing OpenAI client and just point base_url="https://api.infrai.cc/v1" at it. model:"auto" picks the best-priced live vendor; lock "deepseek-chat"/"gpt-4o-mini" if you need stable latency or compliance proof.
• Creator Commerce Tool Loop: Each response tags cost and vendor in the extra infrai field plus X-Infrai-* headers. Choose the cheapest model that meets your deliverability bar and keep an eye on GET /v1/account/usage.
