API Documentation Generator That Never Drifts

Docs written by hand drift from the code within weeks. APIGenerator generates the API and its documentation from the same schema, so every change updates both.

Documentation that follows every change

Add a field and the docs, examples and tests update together.
Each API version keeps its own docs, so existing clients read what they use.
Contract tests fail when the implementation and the docs disagree.

Questions about api documentation generator

Hosted docs come with every API, and the exported project includes the OpenAPI document to publish wherever your docs live.

Yes. Add descriptions to resources, fields and endpoints, and they appear in the reference and in the MCP tool descriptions.

No. Documentation is part of every plan.

Generate docs that stay correct

Generate an API and get its documentation with it.
