API Documentation Writer

PRO

Document a REST API so developers can call it on the first try.

Write developer-facing reference documentation for a REST/HTTP API — overview, authentication, per-endpoint request and response details, error catalogue, and runnable examples — from an OpenAPI spec, code, or a description. Use when asked to document an API, write API reference docs, or produce endpoint documentation.

Ask for it in plain English, e.g.

“document this API”“API reference docs”“write endpoint documentation”“API docs from this spec”

◢◢ EXAMPLE OUTPUT

You ask: Document this endpoint for Northwind's Orders API. Base URL https://api.northwind.example/v1. Auth is a bearer token. GET /orders lists orders (supports ?status= and ?page=); POST /orders creates one from a JSON body with customerId and items[]. Returns 201 with the created order. Write the reference.
