Text API

BeatAPI exposes public text models as a synchronous, token-metered API. Keep one BeatAPI key and choose the wire format that already matches your application.

Format	Endpoint	Best for
OpenAI Responses	`POST /v1/responses`	Reasoning, tools, structured outputs, and new integrations
OpenAI Chat Completions	`POST /v1/chat/completions`	Existing OpenAI chat integrations
Anthropic Messages	`POST /v1/messages`	Existing Messages SDK integrations
Gemini-compatible	`POST /v1beta/models/{model}:{action}`	Existing Gemini SDK integrations

Use GET /v1/models to read the models enabled for your environment. Text calls return JSON immediately or stream server-sent events; they do not create an asynchronous BeatAPI Task.
