Give Claude your OpenAPI spec and ask for a handcrafted typed API client — clean method names, custom error handling, and TanStack Query hooks, without the ugly auto-gen output.
Convert your existing REST API routes into fully typed tRPC procedures with Zod validation — Claude reads your handlers and generates the routers.
Scaffold a custom MCP server with Claude to give it direct access to your internal APIs, dashboards, and microservices.
Generate typed, immutable Data Transfer Objects with validation and factory methods for your API endpoints in PHP or TypeScript.
Point Claude Code at your existing cloud provider using CLAUDE_CODE_USE_BEDROCK or CLAUDE_CODE_USE_VERTEX — no direct Anthropic API key required, and all traffic stays within your cloud security boundary.
API versioning keeps old clients working while you evolve your interface — Claude scaffolds the routing structure and deprecation headers in one prompt.
Idempotency keys prevent duplicate charges and double-submitted orders when clients retry failed requests — Claude scaffolds the middleware in one prompt.
Every production app needs a health check endpoint for load balancers and container orchestrators — Claude scaffolds a robust one in seconds.
Prevent cascading failures in distributed systems by asking Claude to wire up a circuit breaker — describe the thresholds and it handles the state machine.
Distributed tracing turns mysterious slowdowns into pinpointed bottlenecks. Ask Claude to wire up OpenTelemetry across your application without digging through the docs.
External API calls fail. Retry logic with exponential backoff is boilerplate most developers put off — hand it to Claude instead and get it done properly.
Stop writing API clients by hand. If you have an OpenAPI or Swagger spec, Claude can generate a fully-typed client that matches your codebase conventions in minutes.
