How this service works
Score up to 100 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 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-100?utm_source=zero.xyzWhen 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
