GLM Coding Plan Sniper

Auto-purchase script for Zhipu's GLM Coding Plan — automatically places orders at 10:00 AM daily.

Why

GLM Coding Plan releases limited stock at 10:00 AM (UTC+8) daily and sells out within seconds. This script automates the entire flow: intercept sold-out status -> click purchase -> confirm order. All you need to do is scan the QR code to pay.

Features

• Sold-out Bypass — Intercepts soldOut flags during the purchase window (9:59 ~ 10:30) to enable buttons
• Fallback Plan Queue — Configure a priority list of plans; if the primary is sold out, the script automatically falls back to the next candidate in order, cycling through all options before giving up
• Plan Selection — Defaults to Pro + Quarterly billing (configurable via planPriority)
• Precision Timing — Auto-clicks the purchase button at 10:00:00 with 100ms retry interval, up to 300 retries (30 seconds per round)
• Auto Confirm — Automatically clicks confirm/pay buttons in popups
• QR Detection — Plays an alert sound when the payment QR code appears
• Overlay UI — Real-time countdown, log, and payment safety warning displayed in the top-right corner
• Auto Refresh — Refreshes the page at 9:59:50 to fetch the latest state
• API Auto-Retry — Automatically retries failed fetch/XHR requests (429/500/502/503) up to 8 times with incremental delay
• Smart Modal Protection — Detects CAPTCHA and payment modals by content (not just CSS class), freezes all refresh logic to protect them; auto-resumes when modal disappears
• Auto Re-trigger — After each retry round or page recovery, automatically re-triggers the purchase flow (no manual intervention needed throughout 10:30)
• Error Page Recovery — Three-tier recovery when the page shows "too many visitors":
  1. DOM-level suppression: hides the error and re-triggers SPA data loading via pushState/popstate
  2. Full page refresh with cache-busting as fallback
  3. Recovery window covers 10:30, ensuring continued retries
• productId Persistence — Saves the captured productId to localStorage (12h TTL, isolated by plan/period); restored immediately on page refresh without waiting for API response, eliminating race conditions
• System Notifications — Sends a browser notification when sold out or when the payment QR appears, so you don't miss it even if the tab is in the background
• Preconnect Warm-up — Injects <link rel="preconnect"> before the rush to establish TCP/TLS connections at the browser level, faster than fetch HEAD
• Resilient Plan Matching — Identifies plans by price with exact match first, then falls back to non-overlapping price ranges (Lite: ¥30–80, Pro: ¥100–200, Max: ¥350–550), so discounted prices (e.g. 9折) still match correctly

Two Versions

File	Description
glm-coding-sniper.user.js	Tampermonkey userscript — runs automatically after installation (recommended)
glm-coding-sniper-console.js	Browser console version — paste into F12 Console, fallback when Tampermonkey is unavailable (now feature-complete with Tampermonkey version)

Usage

Tampermonkey (Recommended)

One-click install (v1.4.1): Install Tampermonkey first, then click 👉 Install Script — Tampermonkey will automatically pop up the install page.

Or install manually:

1. Install the Tampermonkey browser extension
2. Enable Developer Mode in Chrome (chrome://extensions, top-right toggle)
3. Create a new script in Tampermonkey, paste the contents of glm-coding-sniper.user.js, and save
4. Open https://open.bigmodel.cn/glm-coding around 9:55 AM and make sure you're logged in
5. A black overlay in the top-right corner = script is running
6. Do not click any buttons manually — let the script handle it
7. When you hear the beep, scan the QR code to pay immediately

Console Version

1. Open the purchase page around 9:59 AM and log in
2. Press F12 -> Console tab
3. Paste the entire contents of glm-coding-sniper-console.js and press Enter
4. Overlay appears = success (you'll need to re-paste after any page refresh)

Configuration

Edit the CONFIG object at the top of the script:

const CONFIG = {
  // Priority list of plans to attempt, in order.
  // The first entry is the primary target; subsequent entries are fallbacks.
  // Each entry: { plan: 'lite'|'pro'|'max', billingPeriod: 'monthly'|'quarterly'|'yearly' }
  planPriority: [
    { plan: 'pro', billingPeriod: 'quarterly' },
    // { plan: 'lite', billingPeriod: 'quarterly' }, // fallback (uncomment to enable)
  ],
  targetHour: 10,              // target hour
  targetMinute: 0,             // target minute
  advanceMs: 200,              // ms to start early (compensate network latency)
  retryInterval: 100,          // retry interval in ms
  maxRetries: 300,             // max retry attempts per round (300 * 100ms = 30s)
};

Fallback Plan Example

To try Pro quarterly first, then fall back to Lite quarterly:

planPriority: [
  { plan: 'pro', billingPeriod: 'quarterly' },
  { plan: 'lite', billingPeriod: 'quarterly' },
],

The script cycles through all configured plans. It only stops when every plan has been confirmed sold out for 3 consecutive full cycles — this prevents false positives from brief API fluctuations.

How It Works

This script does not call backend APIs directly. It automates button clicks on the page — all requests are sent by the page's own frontend framework.

Page loads → Intercept soldOut to enable buttons → Auto-click "Subscribe" at 10:00
→ Auto-click confirm popup → CAPTCHA appears (manual) → QR code appears → Scan to pay

If the purchase attempt times out (30 seconds), the script resets and waits for the page to recover, then automatically re-triggers — this cycle repeats throughout 10:30.

If the page shows "too many visitors" error, the script handles it in layers:

API returns 429/5xx → fetch/XHR auto-retry (up to 8 times, incremental delay)
→ If error page still renders → DOM suppression (hide error + pushState re-trigger)
→ If still broken → full page refresh with cache-busting (every 2s, until 10:30)

If a CAPTCHA or payment modal appears, the script detects it by content (verification/payment keywords) and freezes all refresh logic to protect it. Once the modal disappears, auto-purchasing resumes.

The script cannot bypass CAPTCHAs. If a slider or image verification appears after clicking the purchase button, you need to complete it manually. The script's value is:

1. Speed — clicks at exactly 10:00:00, hundreds of ms faster than a human
2. Fewer steps — auto-selects billing period, auto-clicks purchase and confirm, you only handle CAPTCHA + payment
3. Anti-cache — intercepts soldOut flags so buttons don't stay grayed out due to stale frontend state
4. Resilience — automatically recovers from "too many visitors" errors without manual intervention

Important Notes

• Overlay not appearing? — Reload the tab (Ctrl+R). The script runs on all open.bigmodel.cn pages so it works regardless of how you navigate to the purchase page.
• Buttons stay disabled outside the purchase window — sold-out interception only activates during 9:59~11:00
• Don't open multiple tabs — one is enough, more tabs cause lag
• Have your payment app ready — QR codes expire quickly
• Don't pay if the order shows no amount — if the payment QR appears without a price, do not scan it
• Frontend only — backend inventory validation is unaffected; if it's truly out of stock, the script can't help

Alternatives

If you can't get it after multiple days:

• International version z.ai — no purchase limits, AFF + annual discount brings the price close to domestic
• Alibaba Cloud Bailian — call GLM-5.1 directly on-demand, restocks daily at 9:30 AM

GLM Coding Plan 自动抢购脚本

智谱 GLM Coding Plan 自动抢购脚本，每天 10:00 自动下单。

为什么需要

GLM Coding Plan 每天 10:00 限量放货，几秒售罄，纯手动根本抢不到。此脚本自动完成"拦截售罄状态 -> 点击购买 -> 确认订单"全流程，你只需扫码付款。

功能

• 售罄状态拦截 — 在抢购窗口期（9:59 ~ 10:30）自动将 soldOut 改为 false，让按钮可点击
• 候补套餐队列 — 可配置多个候补套餐，首选售罄后自动按优先级切换到下一个，走完一整圈仍全售罄才放弃
• 自动选择套餐 — 默认选择 Pro + 连续包季（可通过 planPriority 配置）
• 精准定时 — 10:00:00 自动点击购买按钮，100ms 间隔重试，每轮最多 300 次（30秒）
• 自动确认 — 自动点击弹窗中的确认/支付按钮
• 二维码检测 — 检测到支付二维码后播放提示音
• 悬浮窗 — 右上角实时显示倒计时、运行日志和付款安全提示
• 自动刷新 — 9:59:50 自动刷新页面获取最新状态
• API 自动重试 — fetch/XHR 请求遇到 429/500/502/503 自动重试最多 8 次，递增延迟
• 智能弹窗保护 — 通过内容（而非 CSS 类名）检测验证码/支付弹窗，出现时冻结所有刷新逻辑；弹窗消失后自动恢复
• 自动重新触发 — 每轮重试结束或页面恢复后自动重新发起抢购，10:30无需手动干预
• 错误页面自动恢复 — "访问人数较多"三级恢复策略：
  1. DOM 级抑制：隐藏错误内容，通过 pushState/popstate 触发 SPA 重新加载数据
  2. 全页面强制刷新（带 cache-busting 参数）兜底
  3. 恢复窗口覆盖10:30，确保持续重试
• productId 持久化 — 捕获的 productId 写入 localStorage（12小时有效，按套餐/周期隔离），页面刷新后立即恢复，无需等待 API 响应，彻底解决时序竞争问题
• 系统通知 — 售罄或支付二维码出现时发送浏览器系统通知，标签页在后台也不会错过
• Preconnect 预热 — 抢购前注入 <link rel="preconnect"> 由浏览器原生建立 TCP/TLS 连接，比 fetch HEAD 更早更高效
• 套餐价格兜底匹配 — 先通过原价精确匹配套餐，失败时自动降级为价格区间匹配（Lite: ¥30–80，Pro: ¥100–200，Max: ¥350–550），即使 monthlyOriginalAmount 为折后价（如包季9折 ¥134.1）也能正确识别

两个版本

文件	说明
glm-coding-sniper.user.js	Tampermonkey 油猴脚本，安装后自动运行，推荐使用
glm-coding-sniper-console.js	浏览器控制台版，直接粘贴到 F12 Console 运行，Tampermonkey 不可用时的备选（已与油猴版功能同步）

使用方法

Tampermonkey 版（推荐）

一键安装 (v1.4.1)： 先安装 Tampermonkey，然后点击 👉 安装脚本 — Tampermonkey 会自动弹出安装页面。

或手动安装：

1. 安装 Tampermonkey 浏览器扩展
2. 确保 Chrome 已开启开发者模式（chrome://extensions 右上角）
3. 在 Tampermonkey 中创建新脚本，粘贴 glm-coding-sniper.user.js 的内容，保存
4. 9:55 左右打开 https://open.bigmodel.cn/glm-coding ，确保已登录
5. 右上角出现黑色悬浮窗 = 脚本运行中
6. 不要手动点任何按钮，等脚本自动操作
7. 听到"嘟嘟嘟"提示音后立即扫码付款

控制台版

1. 9:59 打开购买页面并登录
2. 按 F12 -> Console 标签
3. 粘贴 glm-coding-sniper-console.js 全部内容，回车
4. 看到悬浮窗 = 成功（刷新页面后需重新粘贴）

配置

修改脚本顶部 CONFIG 对象：

const CONFIG = {
  // 套餐优先级列表，按顺序尝试；第一个为首选，后续为候补
  // 每项: { plan: 'lite'|'pro'|'max', billingPeriod: 'monthly'|'quarterly'|'yearly' }
  planPriority: [
    { plan: 'pro', billingPeriod: 'quarterly' },
    // { plan: 'lite', billingPeriod: 'quarterly' }, // 候补（取消注释以启用）
  ],
  targetHour: 10,              // 抢购小时
  targetMinute: 0,             // 抢购分钟
  advanceMs: 200,              // 提前多少ms开始（补偿网络延迟）
  retryInterval: 100,          // 重试间隔ms
  maxRetries: 300,             // 每轮最大重试次数（300次 * 100ms = 30秒）
};

候补套餐配置示例

先抢 Pro 包季，售罄后自动切换到 Lite 包季：

planPriority: [
  { plan: 'pro', billingPeriod: 'quarterly' },
  { plan: 'lite', billingPeriod: 'quarterly' },
],

脚本会循环遍历所有已配置套餐。只有当所有套餐连续 3 整圈均已确认售罄时才会停止，单次 API 波动不会触发放弃，避免误判。

工作原理

脚本不会直接调用后端 API，本质上就是替你点按钮，所有请求都由页面前端框架发出。

页面加载 → 拦截 soldOut 让按钮可点 → 10:00 自动点"特惠订阅"
→ 自动点确认弹窗 → 弹出验证码（需手动完成）→ 弹出支付二维码 → 扫码付款

如果本轮重试超时（30秒），脚本会自动重置状态并等待页面恢复后重新触发，10:30持续循环。

如果页面显示"当前访问人数较多"，脚本会分层处理：

API 返回 429/5xx → fetch/XHR 自动重试（最多8次，递增延迟）
→ 错误页面仍然渲染 → DOM 级抑制（隐藏错误 + pushState 触发重新加载）
→ 仍然异常 → 全页面强刷（每2秒，带时间戳绕缓存，持续到10:30）

如果出现验证码或支付弹窗，脚本通过内容关键词（验证/滑动/支付等）检测，冻结所有刷新逻辑以保护弹窗；弹窗消失后自动恢复抢购。

脚本无法绕过验证码。 如果点击购买按钮后弹出滑块或图形验证，需要你手动完成。脚本的价值在于：

1. 抢时间 — 10:00:00 精准点击，比手动快几百毫秒
2. 省操作 — 自动选包季、自动点购买、自动点确认，你只管过验证码 + 扫码付款
3. 防缓存 — 拦截 soldOut 状态，防止按钮因前端缓存显示灰色
4. 抗限流 — "访问人数较多"自动恢复，无需手动刷新

注意事项

• 悬浮窗没有出现？ — 刷新页面（Ctrl+R）。脚本在整个 open.bigmodel.cn 域名下运行，无论从哪里导航到购买页都能正常工作。
• 非抢购时段点击无效 — 售罄拦截只在 9:59~11:00 窗口期生效，其他时间按钮保持原样
• 不要开多个标签页 — 一个就够，多了浏览器卡反而慢
• 提前准备支付 — 把支付宝/微信打开，二维码有效期很短
• 订单无金额不要付款 — 如果支付二维码出现但订单没有显示金额，请不要扫码
• 脚本只改前端 — 后端库存校验不受影响，抢不到说明确实没货了

替代方案

如果连续多天抢不到，考虑：

• 国际版 z.ai — 不限购，AFF + 包年折扣后价格接近国内
• 阿里云百炼 — 可直接按量调用 GLM-5.1，每日 9:30 补货
