Responses

Create a model response

OpenAI-compatible Responses API endpoint. SandBase validates model and stream for routing, rewrites model to the selected provider mapping, and preserves other request fields. Responses are rebuilt from public OpenAI fields: unknown provider, routing, account, and billing extensions are removed. Unsafe responses fail closed instead of being forwarded.
