x402 API Key + URL Packs: Api Codex Key Pack 50
URL + Key pack with $50 quota. Standalone x402 URL + Key quota pack checkout with a $0.009 URL readiness check and a $1 quota key trial pack priced at $0.12. Browsers can inspect the quote, but payment requires a buyer-owned runtime that signs and retries the same request with X-PAYMENT. Buyers can download the route-specific first-payment client at https://x402-key.558686.xyz/x402/route/api-codex-key-pack-50/first-payment-client.mjs, run node first-payment-client.mjs for quote-only checks, then opt into a buyer-owned x402 payment with PAY_REAL_X402=1. Copy-ready first paid request: curl -fsSL https://x402-key.558686.xyz/x402/route/api-codex-key-pack-50/first-payment-client.mjs -o first-payment-client.mjs && npm install @x402/fetch @x402/core @x402/evm @x402/svm viem @solana/kit @scure/bas
Start with a quote-only recipe. Payment signing stays in your project.
const response = await fetch("https://x402-key.558686.xyz/v1/paid/api-codex-key-pack-50", {
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.
