curl -sS -g -i -X POST 'https://x402-trust.com/v1/watch-endpoint-30d' \
  -H 'content-type: application/json' \
  --data-raw '{"delivery":{"slack_url":"https://hooks.slack.com/services/\u2026","webhook_urls":["https://your-app.example.com/x402-alerts","https://backup.example.com/x402-alerts"]},"endpoint":"https://api.example.com/v1/thing","events":["payto_change","price_change","delisting"],"liveness_sensitivity_n":2}'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
