API Doc Generator

Point this at a codebase, an OpenAPI/Swagger spec, or just describe your API in plain English. It outputs structured, readable documentation: endpoint listings, request/response examples, authentication requirements, error codes, and usage notes.

Works with REST and GraphQL. For REST, it extracts routes, methods, parameters, and response shapes. For GraphQL, it documents queries, mutations, subscriptions, and type definitions. Handles both annotated source files and unannotated code with reasonable inference.

The output is markdown you can drop into a docs site, a README, or hand to a new developer. Consistent format every time, no copy-paste archaeology through controller files.
