Workflow
-
Gather API information. Determine the API type (REST, GraphQL, WebSocket, gRPC), authentication method (API key, OAuth, JWT), base URL and versioning strategy, available endpoints and their purposes, request/response formats, and any rate limiting or usage restrictions.
-
Build the documentation structure. Cover every section in
references/documentation-structure.md, ordering the most common operations first. -
Generate the output. Follow
references/output-template.mdfor REST APIs; adapt to schema, query, mutation, and subscription examples for GraphQL. Replace all placeholders with realistic example data and show both request and response. -
Document errors and rate limits. Include the standard error response format, common error codes, troubleshooting guidance, limits, headers to check, and how to handle
429responses. -
Provide code samples in multiple languages (curl, JavaScript, Python) and link SDKs, Postman collections, or OpenAPI specs where available.
-
Verify quality against the checklist in
references/best-practices.mdbefore delivering.
