x402 Trust Bulk Score Lookup
x402
x402 Trust Bulk Score Lookup is a paid API for AI agents from x402-trust.com, paid per call via x402, $0.4/call, status unknown (last checked 2026-09-15).
Returns trust, reputation, and reliability scores for up to 200 x402 endpoints in a single batch call, including uptime stats, compliance grades, on-chain settlement volume, and a proceed/avoid recommendation.

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 an array of per-endpoint results (up to 200), each with a letter grade (A–F), numeric score, 30-day uptime probe stats, 402-envelope compliance count, on-chain USDC settlement volume, distinct payer count, average latency, price change history, a proceed/avoid recommendation, confidence score with breakdown, sub-scores for technical reliability, spec compliance, and economic reputation, plus a scoreRange and flags. Endpoints not found in the index return a minimal not-found record.
Example use cases
Pre-integration vetting of x402 APIs
“Before I start integrating these five x402 APIs into my agent, can you run them through x402 Trust and tell me which ones have an A or B grade and are safe to proceed with?”
Agent autonomously validating payment targets
“I'm about to let my agent pay x402 endpoints automatically — can you check the trust scores for all 20 endpoints on my list and flag any that have low uptime, compliance issues, or low settlement volume?”
Comparing competing x402 data providers
“I'm trying to pick between three x402 weather data APIs. Can you get me the full trust breakdown for each — uptime, settlement volume, latency, compliance score — so I can compare them side by side?”
Technical details
Endpoint
POSThttps://x402-trust.com/v1/x402-trust-bulk-200When to prefer
Use this endpoint when you need to evaluate the trustworthiness of multiple x402 endpoints in a single call — particularly when your agent is deciding whether to send USDC payments to APIs it hasn't used before. Prefer this over single-endpoint lookups when you have 2–200 URLs to check at once. It is especially valuable for agent orchestration systems that dynamically discover and vet x402 services before paying them.
Side effects
- Unknown endpoint URL returns found:false with null score and grade
- Malformed resource URL in the array may cause a validation error
- Requesting more than 200 resources in one call may be rejected or truncated
- Stale probe data (live:false) may mean scores reflect older measurements
- Low confidence score when endpoint has limited observation history
