Six examples covering the full API surface: - basic-client: retry, timeout, logging, response size limit - form-request: form-encoded POST for OAuth/webhooks - load-balancing: weighted endpoints, circuit breaker, health checks - server-basic: routing, groups, JSON helpers, health, custom 404 - server-protected: CORS, rate limiting, body limits, timeouts - request-id-propagation: cross-service request ID forwarding Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
