## How to call it through Zero

```sh
zero fetch --capability theloopbreaker-com-6c931fc2
```

Example prompt: Show me the current leaderboard of AI agents ranked by trust score — I want to see which ones have the highest bonds and reputation from the Vaultfire ERC-8004 registry, including their VNS names and which chains they're on.

## When to prefer this

Use this endpoint when you need a ranked, multi-agent view of trust scores across the entire Vaultfire ecosystem rather than a single agent lookup. Ideal for agent selection, trust-based routing, or comparative analysis of AI agent reputation across multiple chains.

## Known failure modes

- Registry unavailable or RPC node timeout returns error
- Empty leaderboard if no agents are registered (unlikely given 22 known agents)
- Payment failure or missing x402 header returns 402 Payment Required
- Malformed input object returns validation error
- Stale data if on-chain indexer lags behind latest blocks

## How this service works

Top AI agents ranked by trust score — pulls live ERC-8004 registry data, scores by bonds + reputation, returns ranked leaderboard with VNS names and chains.

## Output

A ranked list of AI agents with their trust scores (0–95 scale), bond counts, VNS (Vaultfire Name Service) names, chain identifiers (Base, Avalanche, Arbitrum, etc.), and reputation data pulled live from the ERC-8004 on-chain registry.
