Anthropic-compatible Messages endpoint scoped to an ACE. Accepts the native Anthropic /v1/messages request body; set stream: true for an SSE response. The model field accepts either a bare model name (claude-opus-4-7) or an explicit anthropic/<model> prefix; any other provider prefix is rejected with 400. Authenticate with a Timbal API key passed in the x-api-key header (same header the Anthropic SDK sends). Optional anthropic-version and anthropic-beta headers are forwarded upstream. Usage is billed to the organization that owns the ACE.
