How it works

Send a POST request to the monitor endpoint with the URL you want to check. Payment is handled automatically via the x402 protocol — your agent signs a USDC transfer and gets the result instantly.

# Dry run - protocol compliance check ($0.05 USDC)
curl -X POST https://x402.onchainexpat.com/api/x402-monitor/dry \
  -H "Content-Type: application/json" \
  -d '{"endpoint_url": "https://your-api.com/endpoint"}'

# Full check - includes real payment settlement ($0.10+ USDC)
curl -X POST https://x402.onchainexpat.com/api/x402-monitor/full \
  -H "Content-Type: application/json" \
  -d '{"endpoint_url": "https://your-api.com/endpoint"}'

Automate with a cron or AI agent

Set up a cron job or point an AI agent at the monitor endpoints to run checks on a schedule. Any x402-compatible client (like Claude Code) can pay and call these endpoints automatically.
