# 1) An unpaid request returns HTTP 402 with the exact payment terms:
curl -i "https://sentineltrust.xyz/v1/reputation?queryParams={'agent': {'description': 'Agent name or wallet address. Partial matches supported.', 'type': 'string'}}"
# 2) Paying + retrying requires an x402 client that can sign the USDC
# authorization (curl alone cannot). See the JS / Python tabs below.
