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 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-50When 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
