Checkpoint: Production-Style API Client

intermediate20 min readLesson 96 of 169

A client class with injected transport, defensive parsing, and bounded retries.

Assemble the module: a small client class that injects its transport, classifies responses, retries transients, and never hangs.

Working with AI: paste your client and ask "how does this behave on a 500? on a 429? on garbage bytes?" — if you can't answer from the code, restructure.
