Codex subscription + API relay

Codex Subscription and API Relay

MyCodex API: same-price anchors with about 2x visible usage

Buy Codex usage like a subscription, then connect the same allowance to your own tools, agents, and projects through an OpenAI-compatible API.

Try freeView pricing

Codex subscription

Buy MyCodex API and agent coding usage through Go, Plus, Pro 5x, or Pro 20x plans.

API relay

Issue Dashboard API Keys from the same account for Cursor, Cline, Open WebUI, custom agents, and the OpenAI SDK.

Server-side secret boundary

Upstream tokens, local Codex config, prehook files, prompts, and private context stay server-side.

Heavy AI coding / agent users

Buy higher Codex usage with a fixed monthly fee while keeping dashboard visibility, limit reasons, and add-on paths.

Independent developers / small products

Connect an OpenAI-compatible endpoint to tools, bots, automation scripts, and customer projects.

Small teams / courses

Use Business shared pools, project keys, member budgets, and billing exports instead of shared accounts.

Product logic

One account, two usage modes

Subscription users care about Codex capacity; API users care about base_url, API key, and model. Both paths share plans, fair-use, add-ons, referrals, and metadata-only ledgers.

View plans

Subscription path

Free, Go, Plus, Pro 5x, Pro 20x, and Business show visible monthly usage and limit behavior.

API path

Dashboard API Keys call /api/v1/codex/* while the server verifies plan, allowance, concurrency, and risk controls.

Secret boundary

Customers get a platform key; owner-side tokens, Codex config, prehooks, and private context stay server-side.

Subscription and API usage share one account and allowance

Individuals can treat it as a Codex usage subscription. Developers and teams can connect the same allowance to an OpenAI-compatible API. Migration should only require changing base_url, api_key, and model; customers do not upload their own upstream key.

The free trial grants successful calls only, not a stockpiled wallet balance.
At the limit, show throttling, queueing, add-ons, or upgrade paths instead of silently dropping requests.
Metadata-only usage logs record request id, plan, usage, capacity state, and error code.

MyCodex API quickstart

Copy these MyCodex 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 usage subscription.
