Venice Responses API (Alpha)

POST /api/v1/responses is Venice's OpenAI-compatible Responses endpoint. It returns a structured, typed output array instead of a single message.content string — ideal for agents that need to separate reasoning, messages, tool calls, and built-in tool events.

Alpha. Access is gated behind the responsesApiEnabled flag on Bearer API keys (staff-only during beta). x402 wallet auth bypasses this flag — you can pay per request without the flag. Schemas may change.

Use when

• You need the OpenAI Responses-style response shape (output[] with typed type: "reasoning" | "message" | "function_call" | "web_search_call" blocks) for a client library that expects it.
• You want clean separation of reasoning vs message vs tool-call output.
• You want streaming via SSE with typed events.

Otherwise use venice-chat — it has more features, more models, and full Venice parameters.
