Codex Subscription Plans

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

Plans cover both Codex subscription usage and Dashboard API Key calls. Pricing maps to official Go, Plus, Pro, and Business anchors while adding API form factor, unified allowance, and about 2x visible usage.

Get API KeyView referrals

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.

Plans and usage limits

Same-price official anchors with subscription usage and API usage

P0 does not ask buyers to calculate input/output tokens first. The storefront shows plan allowance, concurrency/RPM, limit behavior, and add-ons; the backend still accounts by request, tokens, model tier, capacity priority, and risk flags.

Add-ons and limit behavior

Go / Plus

Temporary add-on at 25%-50% of the current monthly fee

Avoid churn at the first overage while keeping the entry plan simple.

Pro 5x / Pro 20x

Heavy add-on at 20%-40% of the current monthly fee

Absorb agent spikes without pushing heavy users into low-tier capacity.

Business

Add seats or shared pool capacity separately

Teams buy management, reimbursement, isolation, and predictability.

Must be explicit

Fair-use API access

Every paid plan has fair-use, concurrency, abuse controls, and throttling/queueing rules.
Codex/Auth usage-window state is not a price promise, but it must influence queueing and throttling.
Upstream errors, usage-window errors, and client disconnects should not be charged incorrectly.
Shown before payment

Allowance, limits, and refund framing

Free gives 10 successful calls or 1 trial day, not a stockpiled wallet balance.
Go, Plus, and Pro throttle or queue after fair-use; add-ons can restore capacity.
Business owners can choose automatic add-ons or hard stop when the organization allowance is reached.

Next step: connect first, then pay

Keep the trial message clear: validate GPT API for free, then choose Go, Plus, or Pro after 10 successful calls.
