How this service works
Trust & 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. Pay-per-call trust scores from $0.005; free top-25 leaderboard.
Output
Returns a structured audit object comparing both x402 resource URLs across trust dimensions including uptime, 402-envelope compliance, historical pricing, and real on-chain USDC settlement volume, surfacing which endpoint is more reliable and trustworthy.
Example use cases
Example prompt
“Compare the trust and reliability of these two x402 endpoints for me — https://api.example.com/weather and https://api.other.com/weather — and label the comparison 'weather API shootout' so I can see which one has better uptime, 402 compliance, and on-chain USDC settlement volume.”
Technical details
Endpoint
POSThttps://x402.fuchss.app/v1/x402-quote-auditWhen to prefer
Use this endpoint when you need to directly compare two x402 endpoints head-to-head on trust, uptime, compliance, and settlement metrics — rather than just looking up a single endpoint's score or browsing the free top-25 leaderboard. Ideal for agents evaluating which of two competing x402 services to route traffic to.
Side effects
- One or both resource URLs are not valid x402 endpoints — returns error or null scores for that resource
- Endpoint unreachable or times out during probing — partial results or probe failure indicated
- Venice model ID not found in catalog — falls back to cheapest default model or returns error
- Malformed input (missing resourceA or resourceB) — 400 validation error
- Payment of $0.017624 USDC not settled — 402 payment required response before results are returned
