// Pays the $0.005 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.x402node.dev/text/summarize?sentences=Number of sentences to return, default 3, max 10&text=Input text to summarize (required, max 50KB)"

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