OpenAI Responses — with server-side model injection
Wire-compatible with the OpenAI /v1/responses endpoint (also spoken by xAI). The caller supplies body.model as an Appstrate model preset id; the platform resolves the preset, substitutes the real upstream model id, injects the upstream API key as Authorization: Bearer, and forwards the request. All other fields (input, instructions, tools, reasoning, stream, …) pass through untouched.
Streaming responses pass through unchanged; usage is read from the terminal response.completed (or response.incomplete) event for accounting.
Authentication: bearer only — API key with the llm-proxy:call scope (headless) or an OIDC-issued JWT (interactive CLI device-flow, dashboard access token). Cookie sessions are rejected.
POST
/api/llm-proxy/openai-responses/v1/responsesAuthorizationBearer <token>
API key authentication. Use Authorization: Bearer apst_... header. The org is resolved from the key — no X-Org-Id header needed. A key is apst_ + 30 base62 characters + a 6-character base62 CRC32 of those 30, so a malformed key is refused without a lookup.
In: header
Header Parameters
X-Run-Id?string
Optional run id (run_…) to attribute the call to. Populated by appstrate run once the platform mints a remote run record; rolls up into the run's cost/token totals.
Request Body
application/json
OpenAI Responses payload, with model replaced by an Appstrate model preset id. All other fields pass through untouched.
