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
A JSON array of per-endpoint results (up to 100) each containing: trust grade (A–F), numeric score, breakdown subscores (uptime, latency, compliance, stability, activity, age), 30-day probe stats, on-chain USDC settlement volume and distinct payer count, price change history, advertised price details, confidence level, scoreRange (low/high/point), explanations, recommendation (proceed/caution/avoid), and freshness metadata. Endpoints not found in the index are returned with null scores and found:false.
Example use cases
Vetting x402 APIs before agent integration
“Before my agent starts paying these x402 endpoints automatically, can you batch-check all 50 of them for trust grades, uptime over the last 30 days, and whether their 402 envelopes are spec-compliant? Flag any that score below B or have compliance issues.”
Comparing settlement activity across services
“I've got a list of about 80 x402 APIs and I want to know which ones have the most on-chain USDC settlement volume and distinct payers over the past 30 days — can you pull the full economic reputation scores for all of them at once?”
Periodic trust audit for a deployed agent fleet
“Run a bulk trust check on these 100 x402 endpoints my agent fleet currently uses — I need the latest uptime probes, latency stats, and any flags or red marks so I can decide which ones to replace.”
Technical details
Endpoint
POSThttps://x402-trust.com/v1/x402-trust-bulk-100When to prefer
Use this endpoint when you need to evaluate trust, reliability, or payment safety for multiple x402 endpoints simultaneously (up to 100 per call). It is the right choice when your agent must decide which x402 APIs to pay, integrate, or recommend, and needs objective uptime, compliance, and on-chain economic data rather than self-reported claims. Prefer it over the single-endpoint lookup when processing batches for cost efficiency ($0.325 for 100 vs per-item pricing).
Side effects
- Endpoint URL not found in x402-trust index — returns found:false with null scores
- Batch exceeds 100 resources — request rejected or truncated
- Invalid resource URL format — item skipped or error returned
- Service unavailable — HTTP 5xx with no results
- Payment not settled — request blocked before processing
- Stale data for rarely-probed endpoints — low confidence scores returned
