API Reference Documentation Forge

This API docs generator template turns endpoint definitions, schema files, and implementation notes into polished reference documentation. It is built to produce consistent endpoint descriptions, request and response fields, authentication notes, and example payloads. The structure helps teams document APIs faster while keeping the output aligned with the actual contract instead of generic filler text.

It is ideal for platform engineers, backend teams, and developer experience writers who maintain public or internal APIs. The prompt encourages the model to list required parameters, optional parameters, status codes, and common errors in a format that developers can skim quickly. It also supports versioned APIs, which is useful when you need separate docs for v1 and v2 or when deprecations must be called out clearly. Use it whenever a schema changes and the docs need to catch up without manual rewriting.

Customize the template by providing {{API_SPEC}}, {{AUTH_METHOD}}, and {{TARGET_READERS}}. Add {{EXAMPLE_REQUESTS}}, {{ERROR_CODES}}, and {{VERSION}} to generate more complete reference pages. The output should be a structured API guide with endpoint tables, request examples, response examples, and notes on rate limits or edge cases. For best results, include the exact base URL and any naming conventions so the model can mirror your real API shape and terminology.
