What should I use for docs that stay synced with the API?

OpenAI APIWeb search: off
Use OpenAPI/Swagger for REST APIs.
Why:
- It gives you a single source of truth for endpoints, request/response shapes, auth, etc.
- You can generate docs automatically from the spec and keep them in sync.
- It also enables client SDK generation, testing tools, and mocks.
Good setup:
- OpenAPI YAML/JSON as the canonical contract
- Render docs with tools like:
- Swagger UI
- Redoc
- Stoplight
- Optionally add:
- Postman collections for interactive testing
- code annotations / decorators if your framework supports generating OpenAPI from code
If your API is GraphQL, use:
- GraphQL schema as the source of truth
- Docs from tools like GraphiQL, Apollo Studio, or schema-driven docs generators
If you tell me your stack (REST vs GraphQL, language/framework), I can suggest the best toolchain.
