How this service works
Score up to 500 x402 endpoints in a single paid call. Each found result carries the FULL trust report — identical to POST /v1/x402-trust: score, grade, scoreRange, recommendation, confidence breakdown, the component/subscore breakdown, explanations, flags + flagsDetailed, advertised price, and 30-day on-chain stats — not just the scalar verdict. Cache rows older than 15 minutes are recomputed on-demand from the latest stored probes and settlements, so scores typically reflect reality within minutes. No live network re-probe is performed — for a fresh live probe use /v1/x402-trust. Per-request recompute limits apply (time + count); results include `recomputed` and `computed_at` so you can see which rows used cached vs freshly computed scores. Resources not in our observation set return `found:false`; you still pay for the batch AS LONG AS at least one resource is tracked. If NONE of the supplied resources are in our observation set the request is rejected with HTTP 400 `notCharged:true` and you are NOT charged. Duplicates are ignored.
Output
A JSON object containing a tiered batch result for each requested URL: trust grade (A–F), numeric score, 30-day uptime probe stats, 402-envelope compliance counts, average latency, on-chain USDC settlement volume and distinct payers, price change history, payTo address, delisting status, confidence levels, sub-scores (technical reliability, spec compliance, economic reputation, economic confidence), score range (low/high/point), breakdown by dimension (age, uptime, latency, activity, stability, compliance), human-readable explanations, a recommendation (proceed/caution/avoid), and freshness metadata. Endpoints not found return nulled fields.
Example use cases
Pre-integration vendor vetting
“Before I start paying any of these x402 APIs, can you check their trust scores, grades, and whether they've had any compliance issues or delistings? Here's a list of 20 endpoint URLs I'm evaluating.”
AI agent marketplace safety audit
“I'm building a marketplace of x402-enabled tools and need to bulk-check trust scores, uptime over 30 days, and on-chain USDC settlement volume for all 80 endpoints currently listed — flag any that score below a B grade.”
Identify unreliable payment endpoints
“Can you run a trust check on these 15 x402 endpoints my agent fleet has been using? I want to see their reliability scores, latency, and whether any have had price changes or low economic confidence so I can stop routing to bad ones.”
Technical details
Endpoint
POSThttps://x402-trust.com/v1/x402-trust-bulk-500?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to evaluate the trustworthiness of multiple x402 payment endpoints at once (up to 500 per call) and want detailed, monitored data including uptime, compliance, and real on-chain settlement volume — not just metadata. Prefer this over the single-endpoint or free-grade endpoints when you need full data breakdowns for batch decisions, vendor audits, or agent routing logic.
Side effects
- Endpoint URL not found in monitoring database — returns found:false with null score
- Batch exceeds 500 resources — likely rejected or truncated
- Invalid URL format in resources array — may cause partial failure
- Payment not completed — endpoint returns 402 without data
- Endpoint recently added with insufficient probe history — low confidence scores
- Stale data if endpoint was not recently probed — indicated by freshness.live=false
