GPT55 API Key + URL Quota Pack
OpenAI-compatible API key plus base URL delivered after x402 payment. Best for agents and apps that need low-latency, high-frequency model calls without signing a payment header on every request. The paid response returns the buyer-owned API key, base_url https://sub2api.558686.xyz/v1, chat completions URL, models URL, quota metadata, and receipt evidence. Callable model range now starts with GPT-5.6 Soul using upstream gpt-5.6-sol, plus gpt-5.6 alias, gpt-5.4-mini, gpt-5.5, gpt-5.3-codex, and gpt-5.4. $10 model quota pack live quote is $1.11112 over x402 Base USDC or Solana USDC when advertised.
Start with a quote-only recipe. Payment signing stays in your project.
const response = await fetch("https://gpt55.558686.xyz/v1/paid/api-codex-key-pack-10", {
method: "GET",
});
console.log(response.status);
console.log(Object.fromEntries(response.headers));
console.log((await response.text()).slice(0, 1000));
// A valid 402 is a quote, not a completed paid call.This sends no payment. Inspect the 402 response before adding a wallet-enabled client.

EVIDENCE
Each record has an exact-route quote outcome. Unresolved templates and potentially mutating methods are labeled instead of being invoked without provider-specific test input. A quote is still separate from a settled paid call.
