FAQs

Codex API Frequently Asked Questions

Codex API, Codex CLI API, API key, pricing, limits, and OpenAI-compatible relay setup.

What is Codex API access on this site?

Codex API access means a buyer-facing OpenAI-compatible relay endpoint with a dashboard API key, base URL, model name, streaming chat completions, pricing tiers, and fair-use controls for Codex CLI-style agent workflows.

Can I use it with Codex CLI?

The setup is designed for tools that support custom OpenAI-compatible base URLs. Use the Codex API base URL, dashboard API key, and model name from the quickstart in Codex CLI-style tools, Cursor, Cline, Open WebUI, curl, or SDK clients.

How do I get a Codex API key?

Use the pricing and dashboard flow to get a customer-facing API key. That key belongs in client tools; private owner-side OpenAI, Codex, OAuth, prompt, prehook, and relay credentials remain server-side.

Is this the official OpenAI Codex API?

No. This site positions an OpenAI-compatible Codex API relay and storefront for developer workflows. It answers OpenAI Codex API search intent without claiming official OpenAI ownership.

Does Codex API access have limits?

Yes. Codex API access uses plan tiers, fair-use windows, concurrency, queueing, and capacity controls. Free access is for setup validation; heavy agent sessions should use paid capacity.

What is the Codex CLI API base URL?

The public relay path is shaped around /api/v1/codex. The exact full base URL depends on the production domain and is shown in the Codex relay quickstart.

Why is my Codex CLI API key not working?

Common causes include using the wrong key type, inactive billing, a revoked dashboard key, a wrong base URL, a mismatched model name, or a client that does not support custom OpenAI-compatible endpoints.

What keywords does the homepage target?

The homepage targets Codex API, Codex CLI, Codex CLI API, Codex API key, OpenAI Codex API, ChatGPT API key, OpenAI-compatible API, Codex API pricing, and Codex API limits.

Can I use the API with Cursor, Cline, or Open WebUI?

Yes, if the client supports OpenAI-compatible base URL configuration. The quickstart shows setup values for Cursor, Cline, Open WebUI, curl, and custom SDK clients.

How does pricing work for Codex API usage?

Pricing is presented as API-shaped access tiers for setup validation, daily individual use, heavy coding agents, high-frequency workflows, and team access, with fair-use and upgrade paths made explicit.
