Codex API
Codex API for OpenAI-Compatible Developer Workflows

Dashboard-issued API key instead of exposing owner-side secrets
Pricing and fair-use copy anchored to the Codex relay plan surface

Codex API endpoint for coding agents
The Codex API page targets developers who want a usable API surface rather than another hosted chat screen. The endpoint is shaped for CLI agents, IDE copilots, automation scripts, and OpenAI-compatible clients that expect a base URL, bearer token, model, and streaming response.
- Use the base URL pattern /api/v1/codex for OpenAI-compatible clients.
- Route chat completion traffic through the frontend relay before it reaches private runtime infrastructure.
- Keep API access, billing, fair-use limits, and setup snippets visible from one buyer-facing page.
Codex API key setup without leaking private tokens
Buyers search for Codex API key, OpenAI Codex API key, or ChatGPT API key when they need something they can paste into a tool today. This page explains the safer product shape: the customer receives a dashboard API key, while owner-side OpenAI, Codex, OAuth, prompt, and relay secrets stay server-side.
- Issue customer-facing service keys from the dashboard.
- Validate requests before forwarding them to the relay.
- Avoid asking users to paste private owner-side credentials into local tools.
Pricing, limits, and fair-use expectations
The strongest commercial traffic often includes pricing, usage, quota, credits, rate limit, and not working modifiers. The Codex API offer should answer those terms directly with plan anchors, fair-use language, queueing expectations, and upgrade paths instead of promising unlimited API usage.
- Expose free validation plus paid capacity tiers for real agent sessions.
- Explain throttling, concurrency, queueing, and add-on paths in plain language.
- Link pricing, setup, and API key management so users can convert after comparison searches.
Codex API setup snippets
Copy the same base URL, API key, and model pattern into Codex CLI-style clients, Cursor, Cline, Open WebUI, curl, or custom OpenAI-compatible SDK calls.
Codex/API quickstart
Copy these Codex API values into Codex CLI-style tools, OpenAI-compatible SDKs, Cursor, Cline, or Open WebUI. The frontend endpoint validates your dashboard API key before forwarding to the private relay; the same account can also be used as a Codex usage subscription.

Codex API FAQ
What is the Codex API on this site?
It is an OpenAI-compatible relay endpoint for Codex-style developer workflows. Customers use a dashboard API key, base URL, and model name to connect CLI tools, IDE agents, and automation clients.
Is this the same as an owner-side OpenAI API key?
No. The buyer gets a customer-facing API key for this relay. Private owner-side platform keys, Codex credentials, and runtime configuration remain server-side.
Which tools can use the Codex API endpoint?
Any client that supports an OpenAI-compatible base URL can be configured, including CLI agents, Cursor, Cline, Open WebUI, curl, and custom SDK calls.
