How this service works
Trust, reputation & reliability scores for x402 endpoints. We monitor every listed x402 service 24/7: uptime probes, 402-envelope compliance, price history, and real on-chain USDC settlement volume. Free grade & recommendation for any endpoint, $0.005 for a full data breakdown.
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-historyWhen 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
