Adding Anthropic API to your Claude Code app? Let us review it.
Expert review for Anthropic API integrations built with Claude Code. We fix Claude Code-generated Anthropic API code for security, error handling & production readiness. From $19.
Common Claude Code issues affecting integrations
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.
Anthropic API issues we find in Claude Code apps
Using completions API format instead of Messages API
AI tools generate code using the deprecated completions format (prompt with Human:/Assistant: turns) instead of the Messages API with its role-based message array.
API key exposed in browser environment
Generated code sends requests to the Anthropic API directly from the client, exposing the API key and violating Anthropic's terms of service.
Tool use response parsing not implemented
AI tools set up tool definitions but don't parse tool_use content blocks in the response or handle the stop_reason: 'tool_use' flow correctly.

Frequently asked questions
Can you review my Claude Code-built Anthropic API integration?
Yes. We regularly audit Anthropic API integrations in Claude Code-built apps. We check for proper error handling, security best practices, and production-ready configuration.
What Anthropic API issues does Claude Code typically create?
Common issues in Claude Code-generated Anthropic API code include: using completions api format instead of messages api, api key exposed in browser environment, tool use response parsing not implemented. We fix all of these in our code review.
How much does it cost to fix my Anthropic API integration?
Start with our code audit ($19) to get a complete list of Anthropic API issues. Most integration fixes are included in our Fix & Ship plan ($199). For complex integrations, we provide a custom quote after the audit.
What Anthropic API best practices does Claude Code typically miss?
AI tools often skip webhook signature verification, proper error handling for API failures, retry logic with exponential backoff, and secure token storage for Anthropic API. Our review checks all of these and provides specific fixes.
