How this service works
Raw observation history for one endpoint over 1-90 days: listing and delisting events, price and payTo changes, and probe results with status and latency. Excluded probes (rate limits, unresolved URL templates, our own resolver outages) never count as downtime. probeSummary aggregates the window.
Output
Returns a JSON object containing: an array of timestamped probe results (reachability, latency in ms, probe status, payment amount), an array of 402-envelope snapshots (listing source, accepted asset details, payment address, network, amount, observation timestamp), and a top-level generatedAt timestamp. Together these let an agent assess the historical reliability, pricing consistency, and on-chain compliance of any x402 endpoint.
Example use cases
Vetting an x402 API before subscribing
“Before I start paying for https://data-feed.example.com/v1/prices, can you check its reliability history on x402 Trust for the last 14 days — I want to see uptime, latency, and whether it's been 402-compliant?”
Auditing payment address changes over time
“Has the USDC payment address for https://ai-api.example.com/v1/generate changed in the last 60 days? Pull the full snapshot history from x402 Trust so I can see any changes.”
Diagnosing a flaky x402 service
“The endpoint https://api.flakyprovider.com/v1/search has been failing intermittently — can you get the last 7 days of probe data from x402 Trust and show me which probes failed and what the latencies looked like?”
Technical details
Endpoint
POSThttps://x402-trust.com/v1/x402-history?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need historical time-series data — probe logs, latency trends, 402-compliance snapshots, or payment address history — for a specific x402 resource URL. It is preferable to the free grade endpoint when you need the full raw data breakdown rather than a summary score, and it is the right choice when auditing, vetting, or debugging an x402 service over a defined historical window.
Side effects
- Unknown or unlisted resource URL returns empty probes and snapshots arrays
- Invalid days parameter (negative or non-integer) may return a 400 error
- Resource URL not monitored by x402 Trust returns no data
- Payment failure for the $0.02 USDC call results in 402 response requiring payment
- Malformed POST body returns validation error
- Endpoint temporarily unavailable returns 5xx
