# 1) An unpaid request returns HTTP 402 with the exact payment terms:
curl -i -X POST "https://mesh.heurist.xyz/x402/agents/UnifaiWeb3NewsAgent/get_web3_news" \
  -H 'content-type: application/json' \
  -d '{"debug": {"default": false, "description": "Debug mode flag. ALWAYS use false.", "type": "boolean"}, "limit": {"default": 10, "description": "Maximum number of news articles to return", "type": "integer"}}'

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