创建音乐任务（异步）
返回的是 job，不是音频。用 GET /v1/jobs/{id} 轮询，直到 status 变成 completed，再从结果里读成品 URL。
生成通常在一分钟以内。返回的成品 URL 在整个保留期内有效 —— 需要时重新读一次 job 拿新链接，不要把 URL 本身缓存下来。
Authorization
bearerAuth Authorization: Bearer <your RouteMux API key>.
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 AUTH_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.
