Built a api / backend service with Claude Code?
We'll make it production-ready.
APIs are the backbone of modern applications — mobile apps, SPAs, integrations, and other services all depend on your API being secure, fast, and reliable. AI tools can scaffold API endpoints quickly, but production APIs need authentication, input validation, rate limiting, documentation, and monitoring that AI tools consistently skip.
API / Backend Service challenges in Claude Code apps
Building a api / backend service with Claude Code is a great start — but these challenges need attention before launch.
Authentication and API keys
Every endpoint needs to verify the caller's identity. AI tools create endpoints without auth, or with auth that's easy to bypass. You need token-based auth, API key management, and proper session handling.
Input validation
Every parameter, request body, and header value must be validated before use. AI-generated APIs trust client data, which leads to injection attacks, data corruption, and crashes from unexpected input.
Rate limiting and abuse prevention
Without rate limits, anyone can hammer your API — brute-forcing passwords, scraping data, or running up your infrastructure costs. Rate limiting must be per-user and per-endpoint.
Error handling and status codes
APIs should return appropriate HTTP status codes (400 for bad input, 401 for unauthorized, 404 for not found, 500 for server errors) with helpful error messages. AI tools often return 200 for everything or expose internal error details.
Documentation
APIs without documentation are unusable. Auto-generated OpenAPI/Swagger docs from your code are the minimum. AI tools rarely set up API documentation.
Versioning and backwards compatibility
Once other services depend on your API, you can't change it freely. You need a versioning strategy from the start so you can evolve the API without breaking existing clients.
What we check in your Claude Code api / backend service
Common Claude Code issues we fix
Beyond api / backend service-specific issues, these are Claude Code patterns we commonly fix.
Over-permissive CORS configuration
Claude Code sometimes sets CORS to allow all origins during development and forgets to restrict it for production, allowing any website to make API requests.
Missing rate limiting
API endpoints are generated without rate limiting, allowing attackers to brute-force auth endpoints or abuse expensive operations.
Over-engineered abstractions
Claude Code creates multiple layers of abstraction, generic utilities, and design patterns for simple problems — making the code harder to understand and maintain.
Edge cases in complex logic
While Claude handles the main flow well, complex conditional logic sometimes has edge cases that produce incorrect results with unusual inputs.

Frequently asked questions
Can I build a api / backend service with Claude Code?
Claude Code is a great starting point for a api / backend service. It handles the initial scaffolding well, but api / backend service apps have specific requirements — authentication and api keys and input validation — that need professional attention before launch.
What issues does Claude Code leave in api / backend service apps?
Common issues include: over-permissive cors configuration, missing rate limiting, over-engineered abstractions. For a api / backend service specifically, these issues are compounded by the need for authentication and api keys.
How do I make my Claude Code api / backend service production-ready?
Start with our code audit ($19) to get a clear picture of what needs fixing. For most Claude Code-built api / backend service apps, the critical path is: security review, then fixing core flow reliability, then deployment. We provide a fixed quote after the audit.
