## 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 theloopbreaker-com-5fc8b638 -d '<json body>'
```

Example prompt: I want to open a validation request on the ERC-8004 Vaultfire registry for agent 0xABC...123 — have 3 independent validators verify the claim that it's a licensed trading agent — post a 0.01 ETH bounty and sign with my wallet.

## When to prefer this

Use this endpoint when you need decentralized, multi-validator on-chain verification of a specific claim about an AI agent, and want the result to be permanently recorded on the ERC-8004 Validation Registry with an ETH bounty incentive. Prefer this over simple trust lookups when you need cryptographic, multi-party attestation rather than a read-only trust score.

## Known failure modes

- Insufficient USDC balance or missing x402 payment header — returns 402 Payment Required
- Invalid or unsigned wallet signature — returns 401 Unauthorized
- ETH bounty amount too low to attract validators — request created but may go unfulfilled
- Agent identifier not found in ERC-8004 registry — returns 404 Not Found
- On-chain transaction reverted due to gas or contract error — returns 500 with revert reason
- Invalid claim format or empty claim body — returns 400 Bad Request

## How this service works

Open a validation request on the ERC-8004 Validation Registry — request that N independent validators verify a claim about an agent. Pay $0.25 USDC, post a bounty in ETH, sign in your wallet to file the request on-chain.

## Output

Returns an on-chain transaction receipt and the newly created validation request ID on the ERC-8004 Validation Registry. The response includes the request's chain status, the number of validators recruited (N), the ETH bounty posted, and a signed receipt confirming the $0.25 USDC x402 payment was processed.
