GPT-5.2 Codex prepaid credits

Prepaid credits, not a vendor subscription

Create a console account, add at least $5, and spend it on gpt-5.2-codex. There is no subscription tier. Developers in mainland China use the same path: prepaid USD credits and requests to https://api.corouter.co.

corouter is not affiliated with OpenAI or Anthropic, and it does not promise network reachability. The account, the balance, and the rate card are what the console and this site publish.
