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
A JSON object containing: a masked and full API key (sk-proj-... format), base URL and chat completions URL pointing to sub2api.558686.xyz, models URL, quota in USD, receipt evidence for the x402 payment, a next-purchase contract string for future top-ups, and metadata about the tool and route used.
Example use cases
On-demand LLM key for agent pipeline
“Spin up a new OpenAI-compatible API key with $1 quota for my automated workflow — use buyer reference 'pipeline-run-42' and hand me the base URL and key so I can start making chat completions calls.”
Temporary credentials for short-lived task
“I need a throwaway LLM API key to run a one-off summarization job — buy me the api-codex-key-pack-1 pack with buyer reference 'task-session-7' and tell me the chat completions URL I should hit.”
Crypto-native AI API access without subscription
“I want to pay for AI API access in USDC without signing up for a monthly plan — grab me a key pack using buyer reference 'crypto-user-99' and show me the API key, base URL, and how much quota I have.”
Technical details
Endpoint
POSThttps://x402-key.558686.xyz/v1/paid/api-codex-key-pack-1When to prefer
Choose this endpoint when you need to programmatically acquire a small, ready-to-use OpenAI-compatible API key and base URL on a pay-per-pack basis via x402 USDC micropayment, without managing long-term subscriptions. It is particularly suited for ephemeral agent pipelines, one-off tasks, or crypto-native workflows where paying per use in stablecoin is preferred over monthly billing.
Side effects
- Payment not received or x402 payment verification fails — returns 402 or error response
- Invalid or missing buyer_reference query parameter — request rejected
- Upstream key quota exhausted — key returned but usable quota may be zero
- Network timeout reaching sub2api.558686.xyz — downstream credential unusable
- Repeated purchase with same buyer_reference may not guarantee idempotency — duplicate charges possible
