Headers & metadata

Relixr-Request-Id, cost, and routing fields on gateway responses.

Request id

Gateway responses include a request id you can paste into Help or /dashboard/usage/[requestId]. Prefer the JSON body id / Relixr extension when present; also look for Relixr-Request-Id on HTTP responses when emitted by the gateway.

Cost & routing

Successful chat completions may include a relixr object with routing decision and cost fields for reconciliation. See Model routing.

Deprecation

Retired model ids may emit Deprecation / Sunset headers. See Deprecation policy.
