_MAKO Agent Commerce Verifier: paid x402 preflight for agents deciding whether to call, trust, or pay another agent/API.

Keywords: agent commerce verifier, x402 trust monitor, paid agent preflight, Bazaar metadata, agent-to-agent payments, USDC.

This endpoint speaks x402: an unpaid request returns HTTP 402 with machine-readable payment terms, your agent pays the $0.25 USDC in USDC on-chain, and retries automatically. Pays to 0x6e4DfBe49858E9Cb93162352D75DBD1E409A7737.

# 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.
