OpenAPI.Docs

<OpenAPI.Root api={api}>
  <OpenAPI.Docs />
</OpenAPI.Root>

OpenAPI.Docs renders a sidebar, the API overview, every endpoint grouped by tag, and every schema. It needs no other setup, which suits small APIs.

For a larger API, give each endpoint its own page instead. This site's API Reference does that, with one page per endpoint. See createOpenAPI.
