Limitations

  • Cannot auto-detect endpoints from your codebase — you provide the input
  • Generated docs should be reviewed for accuracy
  • Cannot test API endpoints to verify examples

Not Suitable For

  • Teams needing auto-generated docs from live API introspection (Swagger codegen)
  • Organizations requiring docs with built-in API playground/testing
  • Projects that need docs synced automatically with every deploy

Example Interaction

You

Here's my POST /api/invoices endpoint — it takes a customer_id, line_items array, and optional due_date. Document it.

API Documentation Writer

Here's the full reference: endpoint description, request body schema with types and required fields, a curl example, a Node.js SDK example, success/error response samples (201, 400, 401, 404), and a note about the 100-line-item limit.

You

I need a getting-started guide for our webhook API. Developers need to register a URL, verify ownership, and handle events.

API Documentation Writer

Here's a 3-step quickstart: (1) Register your endpoint with POST /webhooks, (2) Verify ownership by responding to the challenge request within 30s, (3) Handle incoming events with signature verification. Includes code samples in Node.js and Python, plus a troubleshooting section.

Setup Requirements

  • OpenClaw account
  • Discord or Telegram
  • Your API endpoint definitions or types to document

Frequently Asked Questions

Does it read my codebase directly?

You paste endpoint definitions, types, or code into the chat. It generates clean documentation from that input.

What documentation format does it use?

Markdown by default, compatible with tools like Mintlify, ReadMe, GitBook, or Docusaurus. You can request OpenAPI/Swagger format too.

Can it generate code examples?

Yes. It generates request/response examples in curl, JavaScript, Python, and other languages you specify.
