Most popular for API creators
For power users creating API sessions with Codex API
Buy Codex usage like a subscription, or use your dashboard API key with the frontend Codex relay endpoint for Codex CLI-style tools, OpenAI-compatible SDKs, Cursor, Cline, and Open WebUI. Plans follow ChatGPT price anchors, but the product shape is Codex usage, API endpoint, service key, streaming, and fair-use controls.
Setup validation
Trial access for confirming endpoint, key, model, and streaming setup. Not a production allowance.
Light individual use
Same ChatGPT Go price anchor, API-shaped for developer tools and occasional agents.
Daily individual use
Same ChatGPT Plus price anchor with about 2x perceived usage for API and agent workflows, subject to fair-use.
Heavy coding agents
Higher-priority API access for longer coding and automation sessions. Queue or throttle behavior may apply at capacity boundaries.
High-frequency agents
Highest individual capacity anchor for frequent agents and small production workflows. Add-on packs handle bursts.
Teams and studios
Business price anchor for workspace use. Shared org pools and member budgets depend on runtime rollout state.
Customers receive subscription allowance, a base URL, dashboard API key, and model name instead of owner-side OpenAI or Codex secrets.
Paid plans are governed by runtime fair-use, concurrency, queueing, and capacity windows.
The relay keeps owner-side tokens, local Codex config, prehook files, prompts, and private context server-side.
When fair-use is reached, users should see slowdown, queueing, or add-on/upgrade options instead of silent drops.
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.
