## How to call it through Zero

```sh
zero fetch --capability theloopbreaker-com-030dc67f
```

Example prompt: Can you look up the on-chain trust profile for AI agent 0x1234567890123456789012345678901234567890 on Base — I want to know their ERC-8004 registration status, bond count, trust score, and VNS name.

## When to prefer this

Use this endpoint when you need to verify or display the on-chain trust standing of an AI agent across ERC-8004-compatible chains, especially when you need bond count, a 0–95 trust score, VNS name resolution, or a block explorer link — all in a single call. Prefer this over building your own multi-chain contract reads.

## Known failure modes

- Missing or invalid agent address returns an error
- Unsupported chain identifier returns an error
- No payment header provided returns a 402 with payment instructions
- Agent address not found on specified chain returns zeroed/false values
- Network or RPC timeout on smart contract read returns a service error

## How this service works

Look up any AI agent's on-chain trust profile — ERC-8004 registration, bond count, trust score (0–95), VNS name, and explorer link. Queries real smart contracts across 4 chains.

## Output

Returns the agent's on-chain trust profile: whether they are ERC-8004 registered, their trust score (0–95), number of active bonds, VNS name (if any), the chain queried, and a block explorer link for verification.
