How this service works
Every tool claims to be the best. See which tools actually are best for your agents, starting with agentic web search.
Output
A comprehensive trust verdict object including: overall trust decision, endpoint health/liveness status, measured latency, price drift (actual vs expected), payTo wallet address drift, chain drift, freshness of the verdict, and historical monitoring data for the checked x402 endpoint.
Example use cases
Audit a new web search API before integration
“I'm considering switching to a new agentic search tool for our agent fleet. Can you run a full trust check on it — check its health, latency profile, and whether the price has drifted from what they quoted us?”
Verify payment endpoint before recurring charges
“We're about to set up recurring payments to call our favorite data API. Before we do, can you give me a comprehensive trust report including health status, latency history, and confirm the payTo address hasn't changed?”
Monitor third-party API for price creep
“I've been using this API for months, but I want to make sure the pricing hasn't drifted and the endpoint is still reliable. Can you check the full monitoring history and flag any price changes or wallet address mismatches?”
Technical details
Endpoint
GEThttps://api.x402oracle.com/v1/check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a full, comprehensive trust assessment before paying an x402 endpoint — including historical monitoring context, latency profiling, and multi-dimensional drift checks (price, payTo, chain). Prefer this over the sibling fast-check endpoint when you want the deepest available trust signal and have slightly more time budget, or when auditing a new or unfamiliar x402 endpoint for the first time. Ideal before committing to a higher-value or recurring payment.
Side effects
- Invalid or non-https resource URL returns validation error
- Endpoint is unreachable — health check fails with liveness error
- Price exceeds maxUsdPrice ceiling — trust verdict is negative
- PayTo address does not match expectedPayTo — drift alert returned
- Stale monitoring data exceeds maxAgeSeconds — freshness failure
- Malformed wallet address in expectedPayTo returns schema validation error
- x402 endpoint returns unexpected response format — parsing error
