# x402 Trust Bulk Trust Score Lookup (10 endpoints)

> x402 Trust Bulk Trust Score Lookup (10 endpoints) is a paid API for AI agents from x402-trust.com, paid per call via x402, $0.045/call, status unknown (last checked 2026-09-15).

Returns trust grades, uptime stats, compliance scores, and settlement data for up to 10 x402 endpoints in a single POST call.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability x402-trust-bulk-trust-score-lookup-10-endpoints-df8b6548 -d '<json body>'
```

Example prompt: Can you pull the full trust breakdown for these 10 x402 endpoints — I want to see their grades, uptime, 402 compliance, and USDC settlement volume before I decide which ones to call: [list of endpoint URLs]?

## When to prefer this

Use this endpoint when you need to evaluate multiple x402 endpoints at once (up to 10) and want full data including settlement volume, compliance history, latency, and scored recommendations. Prefer this over the single-endpoint or free-grade endpoints when you need machine-readable subscores and confidence intervals for automated agent decision-making.

## Known failure modes

- Endpoint URL not found in monitoring database — returns found:false with null score
- Invalid resource URL format in input array — may cause validation error
- More than 10 resources submitted — bulk tier limit exceeded
- Network timeout reaching x402-trust.com
- Payment failure via x402 — 402 response not settled, data not returned
- Stale data if endpoint has not been probed recently — freshness.live will be false

## 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 10 per-endpoint results, each with: a letter grade (A–F), numeric trust score, uptime probe stats over 30 days, 402-envelope compliance count, average latency, USDC settlement volume and distinct payer count, price change history, a recommendation (e.g. 'proceed'), confidence score, score range (low/high/point), breakdown subscores (uptime, latency, compliance, activity, stability, age), freshness metadata, advertised price details, and human-readable explanations. Unknown endpoints return found:false with nulls.
