How this service works
API Codex GPT-5.5 Key + URL Pack sold through quote-first x402. Buyer receives a one-time OpenAI-compatible API key plus base URL, chat completions URL, models URL, quota metadata, and receipt evidence after settlement. Quota is $10 and sale price is quotaUsd * 0.111112, the official-price/9 floor for cost=official/18 and 50% gross margin. This is worth buying because it is an immediately usable API credential bundle, not a prompt file or static report. The full API key is returned only in the paid response; public assets expose only masked examples.
Output
After x402 payment settlement, the agent receives a JSON object containing a boolean ok flag, a productId, and a sub2apiCodexKeyPack object with the full API key and base URL for the sub2api Codex group. The key is only revealed in the paid response; unauthenticated requests show only masked examples.
Example use cases
Example prompt
“Buy me a prepaid sub2api Codex API key pack with a $10 quota — I want the API key and base URL delivered after payment so I can start making OpenAI-compatible Codex calls right away.”
