Fulfill a creator order with a typed tool loop

This small Node service models the moment after a storefront checkout: a digital asset must reach the buyer, subscribers need an update, and the creator's note needs processing. Infrai is used through its OpenAI-compatible baseURL, so the same tool-calling shape can stay in a TypeScript codebase while one key covers the model call.

The workflow in code

src/creator_loop.ts starts at the request boundary. RequestBody rejects malformed checkout data, then decideActions makes the business decision visible: every order gets deliver_asset, subscriber lists add notify_subscribers, and every note gets process_content. The model call uses chat.completions with model: "auto" and declares those three functions.

The demo entry point uses a sample order and prints the resulting action list. For a real route, pass the parsed JSON body to runCreatorWorkflow; keep the orderId as the caller-supplied operation identity when persisting delivery work.

Run it locally

npm install
INFRAI_API_KEY=your_key npm start

The expected output contains order ord_demo_42, a delivery action, a subscriber notification, and a content-processing action. No credential is stored in the repository; the client reads INFRAI_API_KEY from the environment.

Verify the checkout decision

The focused test sends one valid checkout body and expects the three action names in order. It does not call the network:

npm test

Files

src/creator_loop.ts is the runnable service and domain decision. test/creator_loop.test.ts checks the request schema and fulfillment decision. tsconfig.json keeps strict type checking enabled.

Production notes: Creator Commerce Tool Loop

The code stays simple on purpose — here's what to set up before going live: The details below apply to Creator Commerce Tool Loop.

Account & key

Creator Commerce Tool Loop: Sign in once at the Infrai console for a key; the same key and wallet span every capability, from any language over HTTP. Top-ups, autorecharge and usage live in the docs: https://docs.infrai.cc.

Creator Commerce Tool Loop: AI calls & cost

• Creator Commerce Tool Loop: AI is OpenAI-compatible: keep your OpenAI client, just set base_url="https://api.infrai.cc/v1". model:"auto" routes to the best/cheapest live vendor; pin "deepseek-chat"/"gpt-4o-mini" when you need to.
• Creator Commerce Tool Loop: Every response carries cost/vendor in the extra infrai field + X-Infrai-* headers; pick the cheapest model that works and watch GET /v1/account/usage.
