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 the provisioned API key (masked and full), the base URL, chat completions URL, models URL, quota in USD, and receipt evidence confirming the x402 payment was processed.
Example use cases
Example prompt
“I need to buy an OpenAI-compatible API key pack via x402 for buyer reference 'buyer-001' — give me the API key, base URL, and chat completions URL with $1 quota.”
Technical details
Endpoint
POSThttps://x402-key.558686.xyz/v1/paid/api-codex-key-pack-100When to prefer
Use this endpoint when you need a ready-to-use OpenAI-compatible API key and base URL provisioned on-demand via x402 micropayment, especially for agents that need LLM access without managing long-term API credentials or subscriptions. Prefer over alternatives when operating in x402-enabled payment flows and needing a small prepaid quota pack quickly.
Side effects
- Payment not received or x402 payment invalid — no key returned
- buyer_reference missing — 400 or validation error
- Upstream quota exhausted — key issued but with zero usable quota
- x402 facilitator not reachable — payment cannot be processed
- Key provisioning backend (sub2api) unavailable — 503 error
