Adding Anthropic API to your GPT Engineer app? Let us review it.
Expert review for Anthropic API integrations built with GPT Engineer. We fix GPT Engineer-generated Anthropic API code for security, error handling & production readiness. From $19.
Common GPT Engineer issues affecting integrations
No authentication system
GPT Engineer generates functional UIs but typically skips authentication entirely. All routes and data are publicly accessible.
Direct database access from client
Some generated apps query databases directly from the frontend without an API layer, exposing database credentials and structure.
Incomplete feature implementations
Features that look complete in the UI but don't actually work end-to-end. Buttons that don't submit, forms that don't save, and links that go nowhere.
Anthropic API issues we find in GPT Engineer 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 GPT Engineer-built Anthropic API integration?
Yes. We regularly audit Anthropic API integrations in GPT Engineer-built apps. We check for proper error handling, security best practices, and production-ready configuration.
What Anthropic API issues does GPT Engineer typically create?
Common issues in GPT Engineer-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 GPT Engineer 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.
