Create keys at https://routemux.com/console/keys. New keys use the sk- prefix;
the legacy rmx_live_ prefix is still accepted.
The Anthropic SDK's x-api-key and the Google SDK's x-goog-api-key are accepted too.
Sending several key headers with different values returns 400 AMBIGUOUS_API_KEY.

Request Body

TypeScript Definitions
Use the request body type in TypeScript.
Request and response bodies match the upstream provider's official format verbatim —
RouteMux passes them through untouched. See the provider's own docs for field definitions;
the gateway itself only reads model and stream.
