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 and unmasked API key (sk-proj-... format), a base URL (https://sub2api.558686.xyz/v1), a chat completions URL, a models URL, the quota in USD (integer, ~$1), receipt evidence for the x402 payment, and metadata like the tool name and route.
Example use cases
Instant LLM access for a new project
“I need a quick OpenAI-compatible API key with a small $1 quota to prototype a chatbot — grab me one using buyer reference 'proj-alpha-test' so I have a base URL and key I can plug in immediately.”
Disposable key for a sandboxed agent
“Set up a throwaway API key pack for my sandboxed agent experiment using buyer reference 'sandbox-run-42' — I want the chat completions URL and key so the agent can make LLM calls without using my main credentials.”
Reselling micro-quota LLM access
“Purchase a 1000-unit API key pack with buyer reference 'resale-client-7' — I need the base URL, key, and quota details so I can pass access on to a client who only needs a small amount of inference.”
Technical details
Endpoint
POSThttps://x402-key.558686.xyz/v1/paid/api-codex-key-pack-1000?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a ready-to-use OpenAI-compatible API key and base URL delivered instantly via a micropayment (x402 protocol), without setting up a subscription or sharing existing credentials. Ideal for agent workflows that need disposable or isolated LLM access, sandboxed experiments, or reselling small quota packs. Prefer alternatives if you need large quotas, direct OpenAI access without a proxy, or if you cannot execute x402 USDC payments.
Side effects
- Payment not completed or x402 payment rejected — no key returned
- Invalid or missing buyer_reference query parameter — request rejected
- Upstream quota exhausted — key provisioned but immediately rate-limited
- x402 facilitator unreachable — payment cannot be processed
- Upstream OpenAI-compatible provider key pool depleted — provisioning fails
- Price mismatch ($111.112 USDC is unusually high relative to $1 quota — potential misconfiguration)
