How this service works
Score up to 50 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 up to 50 results, each with: a letter grade (A–F), numeric score (0–100), score range (low/high/point), uptime probe stats over 30 days, average latency, 402-envelope compliance count, on-chain USDC settlement volume and distinct payers, price change history, payment address, flags, sub-scores (economic confidence, spec compliance, technical reliability, economic reputation), a proceed/caution/avoid recommendation, and a confidence level. Endpoints not yet tracked return found:false with nulls.
Example use cases
Pre-payment vetting of x402 APIs
“Before I start paying these x402 endpoints, can you run a bulk trust check on https://api.service1.com/v1/data, https://api.service2.com/v1/stream, and https://api.service3.com/v1/query — give me the grade, uptime, and whether they're actually settling USDC on-chain?”
Fleet health audit for agent infrastructure
“I have a list of 40 x402 APIs my agent fleet is currently using — can you pull their trust scores and flag any that have poor uptime, compliance issues, or suspicious payment addresses so I know which ones to drop?”
Due diligence before listing an x402 marketplace
“I'm curating an x402 API marketplace and need to vet submissions — can you score these 15 candidate endpoints in bulk and show me which ones pass with a grade of B or above, along with their settlement volumes and compliance breakdowns?”
Technical details
Endpoint
POSThttps://x402-trust.com/v1/x402-trust-bulk-50?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to evaluate multiple x402 endpoints at once (up to 50) and want comprehensive trust data including uptime, 402 compliance, on-chain settlement evidence, and an actionable recommendation — especially before committing automated payments to those endpoints. Prefer this over the single-endpoint grade endpoint when you have a batch to evaluate and want to save per-call costs relative to calling individually.
Side effects
- Exceeds 50-resource limit per call — request rejected
- Unknown or unmonitored endpoint returns found:false with null scores
- Malformed URL in resources array causes validation error
- Payment of 0.20 USDC not completed — request blocked
- Endpoint recently added may have low confidence due to short observation window
- Rate limits may apply if called at high frequency
