How this service works
Buy a low-cost readiness check first, then buy a small OpenAI-compatible URL + API key quota pack through x402, including GPT-5.6 Soul access when your upstream key allows it. The readiness check returns URL, model, request-shape, and next-pack contract details without exposing a key.
Output
Returns a JSON object containing: a (masked) API key (sk-proj-... format), the base URL (https://sub2api.558686.xyz/v1), a chat completions URL, a models URL, the quota amount in USD, and receipt evidence confirming the x402 payment. Deterministic flag and route metadata are also included.
Example use cases
Example prompt
“Buy me an OpenAI-compatible API key and base URL quota pack — about $1 of quota — using my buyer reference 'buyer-001', so I can start making chat completion requests right away.”
Technical details
Endpoint
POSThttps://x402-key.558686.xyz/v1/paid/api-codex-key-pack-10When to prefer
Use this endpoint when you need a quick, low-cost OpenAI-compatible API key + base URL provisioned via x402 micropayment, especially for agents that need to spin up LLM access on-demand without a pre-existing API account. Prefer this over direct OpenAI signup flows when you need instant programmatic key provisioning at small quota sizes ($1 USD range) within an x402-enabled payment pipeline.
Side effects
- Payment not completed or x402 payment header missing — endpoint returns 402 Payment Required
- Invalid or missing buyer_reference query parameter — returns validation error
- Upstream quota pool exhausted — may return an error indicating no keys available
- Payment amount mismatch — x402 facilitator rejects the transaction
- Network timeout reaching sub2api.558686.xyz — key not delivered
