# 1) An unpaid request returns HTTP 402 with the exact payment terms:
curl -i -X POST "https://mako.pollinateresearch.com/api/agent-commerce/verify" \
-H 'content-type: application/json' \
-d '{"intended_task": "Find a low-cost DAO governance proposal signal endpoint", "max_price_usdc": 0.25, "required_output": "json", "risk_mode": "strict", "target_url": "https://mako.pollinateresearch.com"}'
# 2) Paying + retrying requires an x402 client that can sign the USDC
# authorization (curl alone cannot). See the JS / Python tabs below.
