The complete API reference lives at the developers page.

Why it is there and not here

That page is generated from the live API specification, with request and response shapes, per-language code samples and an OpenAPI document you can point tooling at. It is correct by construction and always current.

Restating it here would create a second copy that goes stale, which is exactly the failure these docs are built to avoid.
