Codex is OpenAI's AI coding agent that reads, edits and runs code in your terminal or IDE, turning plain-English request...

About this product

① Built on a large pool of Codex accounts — stable and reliable.

② Works just like the Codex website: same experience, same results.

③ Backed by ChatGPT Pro memberships on the official site — not a fake API or a relay platform. The experience matches the ChatGPT (Codex) membership system.

④ Most importantly, no need to worry about your own account being banned.

⑤ Your purchased time is guaranteed. To buy official Codex instead, see ChatGPT.

Plan benefits

① Plus monthly: US$180 of usage (about 2–3× the official Plus allowance).

② Pro monthly: US$360 of usage (about 3–5× the official Plus allowance).

③ Expected cost: ¥0.2 per US$ of usage. (Given OpenAI's policies and productivity, if you run out, take a break!)

④ The full GPT-5 model family is available; switch models with "/model".

⚠️ Before you buy

① To keep things sustainable, our Codex membership is priced higher and isn't suited to heavy, 24/7 workloads. Members may not use it for more than 9 hours a day (to avoid OpenAI banning accounts for abuse).

② We can only answer a limited range of technical questions. Please ask an AI first (ChatGPT, Grok, Gemini, etc.) and check the Codex documentation for technical details.

How to use

① After you pay, we email a redemption code and the mirror Codex URL to your order email. Register on the mirror Codex site, click Redeem and enter the code to get the corresponding usage.

② Go to API key management, create a key and choose the OpenAI group. Then install and configure it with CC Switch (original project on GitHub) to start using your membership.

How it is delivered

🙋 Manual delivery ⏰ Working hours UTC+8 09:00–21:00 📧 Sent to your order email, also viewable once on the order page

After-sales service

① If you hit a problem, first check the OpenAI status page to see whether Codex is available.

② If a large-scale outage on our side lasts more than a day, you can request compensation and we will issue activation codes for the lost time.

③ If you're not satisfied and request a refund, we refund the unused usage minus a ¥10 fee (e.g. bought a monthly plan for ¥180 and used ¥30: refund 180 − 10 − 30 = ¥140).

How do I receive my order after paying?
