Venice Responses API (Alpha)

POST /api/v1/responses is Venice's OpenAI-compatible Responses endpoint. It returns a typed output array instead of a single message.content string — useful for agents that need to separate reasoning, messages, tool calls, and web-search events. Internally the request is translated to a chat completion, so model support matches venice-chat.

Alpha. The spec labels it Alpha (and its description still says "Alpha testers only"), but access is no longer restricted: any Bearer API key or x402 wallet can call it. Schemas may still change.

Use when

• A client library expects the OpenAI Responses shape (output[] with type: "reasoning" | "message" | "function_call" | "web_search_call").
• You want reasoning, message, and tool-call output cleanly separated.
• You want SSE streaming with typed events.

Otherwise use venice-chat — it has structured output, audio/video/file inputs, E2EE, sampling controls, and every venice_parameters field.
