How this service works
API uptime and reliability monitoring for any x402 endpoint: a live quality verdict covering availability, uptime, latency percentiles, 402-offer conformance, price-drift and payTo-stability flags. Deterministic and re-verifiable.
Output
A structured quality verdict object for the queried x402 endpoint, including: overall quality score and grade, availability status, latency percentile breakdowns (p50/p95/p99), 402-offer conformance result, a price-drift flag indicating whether pricing has changed recently, and a payTo-stability flag indicating whether the payment destination address has been consistent. Results are deterministic and re-verifiable.
Example use cases
Vet a new x402 service before integrating
“Before I start using https://data.someprovider.xyz/v1/feed in my agent, can you check its x402 quality verdict — I want to know if it's available, how the latency looks, and whether the price or payTo address have been stable?”
Debug a misbehaving payment endpoint
“My agent keeps getting weird responses from https://api.paytool.io/v1/enrich — can you run a live verdict on it and tell me if it's failing conformance checks or if the 402 offer looks off?”
Compare reliability of two x402 endpoints
“I'm deciding between https://pulse.serviceA.xyz/v1/score and https://api.serviceB.io/v1/lookup — can you get quality verdicts for both so I can see which one has better availability and lower latency?”
Technical details
Endpoint
GEThttps://pulse.chainverdict.xyz/v1/verdictWhen to prefer
Use this endpoint when you need a live, objective, multi-dimensional quality assessment of a specific x402 endpoint before integrating it, routing traffic to it, or deciding whether to pay for its service. It is especially valuable for detecting price manipulation, payTo address changes, or latency degradation in micropayment APIs. Prefer this over generic uptime monitors because it understands x402 semantics (402 offer structure, payment destination, price conformance) natively.
Side effects
- Invalid or unreachable URL returns an error or degraded verdict
- Non-x402 endpoints may return conformance failure with no useful latency data
- Transient network issues may cause availability to read as down when endpoint is healthy
- Price-drift and payTo flags may lag real-time changes by one probe cycle
- Malformed URL query parameter returns a 400-level error
