/chat/completions

Streaming chat completions. Client POSTs a ChatCompletionRequest with `stream: true`. The server responds with `Content-Type: text/event-stream` and emits a sequence of `chat.completion.chunk` events, terminated by a `data: [DONE]` line. When `stream_options.include_usage` is true, the final chunk before `[DONE]` carries a populated `usage` object and an empty `choices` array.

About AsyncAPI

The AsyncAPI specification describes event-driven APIs the way OpenAPI describes request/response APIs. A channel is the named pipe — a webhook URL, a Kafka topic, a WebSocket route, an MQTT subject — that producers and consumers publish or subscribe to. Each channel carries one or more messages with structured payloads, and an operation declares whether a given party sends or receives on that channel.

Browse every event-driven channel on the APIs.io network or compare with the broader Agent Skill and MCP server surfaces of the same providers.
