Build API clients with retries, timeouts, pagination, and error surfacing baked in, and test them properly. Use when writing a client for an external or internal API.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# API client design An API client is where your code meets an unreliable network and someone else's service. A good client makes the common case simple and the failure cases handled: timeouts, retries, pagination, and clear errors built in, so every caller does not reinvent them badly. ## Method 1. **Bake in timeouts and retries.** Every request has a timeout (connect and read: never infinite: see timeouts-and-retries), and retries with exponential backoff and jitter for the retryable failures (timeouts, 429, 5xx), respecting Retry-After. This logic lives in the client once, correctly, not copy-pasted into every call site where half will get it wrong (see the retry-amplification warning in timeouts-and-retries). 2. **Surface errors clearly and typed.** Map the API's errors (see api-error-responses) into meaningful, catchable types the caller can branch on (NotFoundError vs RateLimitError vs a transient network error), with the useful context (status, error code, request ID for support: see observability). A client that returns raw HTTP errors or swallows them into a generic failure pushes the error-handling burden back …

How to install
mdr add amey-thakur/ai-skills/api-client-design@sha256:d515595c97f25900The line at the top of this page pins the label git:20260728.fac4544, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
