API reference

Every operation of the TrueTone API, grouped by Capability Group: the fields each request takes, what each response carries, the credit price and rate tier of every call, and a copyable curl example. The page renders from the same OpenAPI document the API serves, so nothing shown here can drift from what the API actually does.

That document lives at https://hub.truetone.ai/openapi.json. It is plain OpenAPI 3.1: point your API client at it, or feed it to a code generator, and you get exactly the contract shown here.
