// npm i x402-fetch viem

// Pays the $0.08 USDC automatically on the 402, then returns the real response:

console.log(await res.json());

# 1) An unpaid request returns HTTP 402 with the exact payment terms:
curl -i "https://api.cn402.com/almanac?date=Date YYYY-MM-DD (required)"

# 2) Paying + retrying requires an x402 client that can sign the USDC
#    authorization (curl alone cannot). See the JS / Python tabs below.
