Your question is API Endpoints for Architecture. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
What API endpoints would you need for the app described in the architecture question?
Identify the endpoints required to connect the client, application services, and ML components in the architecture already discussed. For each endpoint, describe its purpose, method, request and response shape, authentication and authorization, latency expectations, error behavior, and idempotency where relevant. Explain how the API design supports model versioning, asynchronous work, observability, and graceful fallback without introducing unnecessary endpoints.
