Adding OpenAI API to your Codex CLI app? Let us review it.
Expert review for OpenAI API integrations built with Codex CLI. We fix Codex CLI-generated OpenAI API code for security, error handling & production readiness. From $19.
Common Codex CLI issues affecting integrations
API keys and secrets written directly into generated source files
Codex CLI generates code with placeholder credentials that developers often replace with real values inline, leaving secrets committed to version control. There is no .env scaffolding or secret management setup by default.
No authentication or authorization on generated API endpoints
When Codex generates Express or FastAPI backends, routes are created without middleware for authentication, meaning every endpoint is publicly accessible immediately after deployment.
Single-file output breaks apart for any real project structure
Codex frequently outputs all logic into one or two files rather than organizing code into modules, services, and utilities — making the result hard to maintain and extend as the codebase grows.
OpenAI API issues we find in Codex CLI apps
API key exposed in client-side code
AI-generated code calls the OpenAI API directly from the browser using NEXT_PUBLIC_ prefixed environment variables, exposing your API key to every visitor.
No rate limiting or cost controls on proxy endpoint
Generated server-side proxy endpoints call OpenAI without rate limiting, allowing users to make unlimited requests and run up thousands of dollars in API costs.
Streaming response not handled correctly
AI tools implement chat streaming but don't properly handle stream errors, connection drops, or the [DONE] sentinel, causing hanging requests or missing response content.

Frequently asked questions
Can you review my Codex CLI-built OpenAI API integration?
Yes. We regularly audit OpenAI API integrations in Codex CLI-built apps. We check for proper error handling, security best practices, and production-ready configuration.
What OpenAI API issues does Codex CLI typically create?
Common issues in Codex CLI-generated OpenAI API code include: api key exposed in client-side code, no rate limiting or cost controls on proxy endpoint, streaming response not handled correctly. We fix all of these in our code review.
How much does it cost to fix my OpenAI API integration?
Start with our code audit ($19) to get a complete list of OpenAI 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 OpenAI API best practices does Codex CLI 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 OpenAI API. Our review checks all of these and provides specific fixes.
