Questions proposed for each lab:

• How is this API documented?

• How does an external consumer understand the contract?

• How are errors standardized?

• How is authentication applied?

• How do I test it?

• How do I monitor it?

• How do I version it without breaking clients?

• How do I know if the API is slow?

• How do I compare REST with gRPC, GraphQL, or WebSockets?
