The surface is narrow on purpose: two metered endpoints and model: "auto". Model identity is not exposed.

Create a response (OpenAI Responses shape)

OpenAI Responses API-compatible endpoint. Same routing/billing semantics as `/chat/completions` and `/messages` — a different wire format for the same catalog-driven model pool.

POST
/responses

OpenAI Responses API-compatible endpoint. Same routing/billing semantics as /chat/completions and /messages — a different wire format for the same catalog-driven model pool.

Authorization

bearerAuth
AuthorizationBearer <token>

A ModelBeat API key, prefixed mb_live_, sent as Authorization: Bearer <key>.

Keys are issued in the ModelBeat console and are scoped to one tenant. The example value used throughout this document (mb_live_EXAMPLE_NOT_A_REAL_KEY_00000000000000000000) is a placeholder and will not authenticate.

Header Parameters

Idempotency-Key?string

Opaque, caller-chosen key that makes a retry safe. The OpenAI SDK — the integration path ModelBeat advertises — retries 5xx and timeouts by default; without this header each retry is a new logical request, i.e. a second reservation and a second charge for one prompt. Send the same key on a retry and ModelBeat returns the original reservation: one hold, one charge.

Reusing a key for a different request body, or one whose reservation was already settled, is refused with 409. Keys longer than 255 characters are ignored (treated as absent).
