How this service works
x402 endpoint health monitoring for 30 days: we run preflight checks on schedule, you poll for the health log
Output
Returns a monitoring job confirmation and a reference for polling the accumulated health log. The log contains timestamped results of preflight checks run against the target endpoint at the specified interval, including whether the 402 challenge, headers, and payment schema responded correctly. Covers a 30-day window.
Example use cases
Monitor new x402 API after launch
“I just launched my paid API at https://api.example.com/reports — can you set up scheduled health checks on it every 15 minutes using GET so I can track whether the 402 challenge keeps working correctly?”
Watch payment endpoint during high traffic
“My x402 POST endpoint at https://payments.myapp.io/execute has been flaky — please start monitoring it every 60 minutes with an empty JSON body so I get a 30-day health log to review.”
Validate x402 uptime for SLA reporting
“I need to prove uptime for my x402 API at https://data.myplatform.net/query — set up checks every 120 minutes via GET and I'll poll the log weekly for my SLA reports.”
Technical details
Endpoint
POSThttps://predator-ubuntu.taild9a745.ts.net/v1/monitor?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need ongoing, scheduled health surveillance of an x402-protocol endpoint over a 30-day window, especially to validate that 402 challenges, payment headers, and preflight responses remain correct. It is purpose-built for x402 APIs, making it more relevant than generic uptime monitors when payment-gating behavior is what you need to track.
Side effects
- Invalid or unreachable URL returns an error immediately
- interval_minutes below 15 or above 1440 is rejected by schema validation
- Method not in [GET, POST] enum is rejected
- Endpoint being monitored may block the monitoring agent's IP, causing false negatives
- Payment of $0.03 USDC must succeed or the monitoring job is not created
