Operational notes

  • Authenticate with `Authorization: Bearer omx_live_xxx`.
  • Omixa handles provider keys, routing, billing, failover, and usage recording behind this endpoint.
  • Google Vertex requests use active Vertex accounts configured by the admin; Omixa retries the next healthy account when a route fails before output starts.
