FAQ

OpenAI API proxy, Base URL, and compatibility

What is an OpenAI API proxy?

It is usually a third-party endpoint that provides OpenAI-compatible request formats, API keys, billing, and Base URLs for apps or developer tools.

Can I use these providers with Codex or Cursor?

Many OpenAI-compatible providers can be tested with tools that accept a custom Base URL and API key. Always verify model names and API compatibility first.

Does OpenAI-compatible mean official OpenAI?

No. OpenAI-compatible usually describes the API format, not official ownership, pricing, availability, or service guarantees.

Is an OpenAI API reverse proxy the same as free OpenAI API access?

No. An OpenAI API reverse proxy is usually an API gateway or AI proxy service between your app and an upstream model provider. It may give you a custom Base URL, API key management, model routing, billing, rate limits, or access to multiple providers through one OpenAI-compatible interface. Some services offer trial credits or lower-cost plans, but they are not the same as free official OpenAI API access. The real question is whether the provider is compatible, stable, transparent about pricing, and safe with your API keys.
