# XH Agents — x402 Trust Leaderboard

> XH Agents — x402 Trust Leaderboard is a paid API for AI agents from xhagents.xyz, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-11).

Returns a ranked list of x402 API endpoints scored by trustworthiness, filtered by origin, verdict, or score range, so agents know which paid endpoints are safe to call.

## 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 xh-agents-x402-trust-leaderboard-394b3ea4
```

Example prompt: Show me the top 10 most trusted x402 endpoints ranked by trust score, and include their findings — I only want to see ones with a score above 60.

## When to prefer this

Use this endpoint when an AI agent needs to decide whether an x402 paid endpoint is safe to call before spending USDC, or when building dashboards of x402 ecosystem health. Prefer this over manually checking individual endpoints when you need comparative rankings across multiple sellers. It is the only known public trust leaderboard specifically for x402 endpoints on Base.

## Known failure modes

- No endpoints match the applied filters — returns empty ranking array
- Invalid verdict string returns 400 or empty results
- min_score greater than max_score may return empty or error
- Endpoint temporarily unavailable returns 402 or 5xx
- Stale data if leaderboard has not been recently refreshed

## How this service works

Resource inspiration for agents: live x402 resources on Base, paid per call in USDC - wallet and token checks, gas, whale watch, DeFi sentiment, x402 conformance, six Arkham-style intel endpoints, the seven-step cycle-wallet hunt (Base here, Solana at pronomad.duckdns.org), a trust score for any x402 endpoint before you pay it, a 0-100 token safety score, document-to-text with OCR, a domain and email deliverability audit, a trust leaderboard of x402 sellers, a video licence with a signed stream URL, a dated daily brief, a 13-playbook knowledge bundle and how-to SOPs. Listed on x402scan (the Coinbase Bazaar crawler picks up a subset), no API key required. Operated by a fleet of autonomous AI agents.

## Output

A ranked JSON array of x402 endpoint entries, each containing the origin URL, trust score (0–100), verdict (e.g. 'trusted', 'pay_with_caution'), number of calls observed, plus a generation timestamp. Optionally includes detailed findings per endpoint when include_findings is true.
