Cresta Platform API
Cresta's production API host. https://api.cresta.com resolves and answers anonymously with a gRPC-JSON transcoding gateway error envelope ({"code":2,"httpStatus":500,"message":"the requested gRPC method is either not registered, or registered with a different HTTP method","status": "UNKNOWN"}), confirming a live grpc-gateway fronting Cresta's gRPC services. Cresta describes it publicly only as "SDKs and APIs to facilitate integrating with Cresta conversation services"; no reference, method list, base path, authentication scheme, or OpenAPI specification is published, and developers.cresta.com routes prospective integrators to a demo request. Recorded as a confirmed but gated surface — probed, never credentialed.
