How this service works
Paid Watchdog registration: 30 days of signed monitoring for one x402 endpoint. Free preview: GET /watchdog/preview
Output
Returns a signed monitoring registration object including schema_version, type, tier, signer identifier, and a cryptographic signature confirming that the specified x402 endpoint is enrolled in 30-day uptime monitoring with alerts delivered to the specified channel.
Example use cases
Uptime monitoring for a payment endpoint
“Set up 30 days of signed watchdog monitoring on https://payments.myservice.com/checkout using a GET method, and send any downtime alerts to ops@mycompany.com.”
Webhook alert on x402 API failure
“I need to monitor my x402 endpoint at https://api.acmecorp.io/v1/token for the next 30 days — register the watchdog and route alerts to https://hooks.acmecorp.io/monitoring whenever it goes down.”
Verifiable monitoring proof for a partner
“Can you register a paid 30-day watchdog on https://partner.example.org/x402/resource with HEAD method and email alerts to compliance@myco.com? I need the signed registration record to prove monitoring is active.”
Technical details
Endpoint
GEThttps://x402.nsgoods.org/watchdog/register/paidWhen to prefer
Choose this endpoint when you need cryptographically signed, verifiable proof of endpoint monitoring (not just informal uptime checks), specifically for x402-protocol endpoints. Prefer it over generic monitoring services when you need a tamper-evident signed registration artifact and 30-day coverage tied to a specific x402 URL and alert channel.
Side effects
- Invalid or non-x402 endpoint URL provided — registration rejected
- Alert channel is malformed (invalid email or non-HTTPS webhook URL)
- Payment of $5 USDC not fulfilled via x402 protocol — 402 response returned
- Unsupported HTTP method supplied (only GET, HEAD, DELETE allowed)
- Endpoint already registered and active — duplicate registration conflict
- Network timeout or provider unavailability during registration
