## 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 blindoracle-agent-reputation-lookup-budget-tracker-agent-d5488366
```

Example prompt: Can you check the BlindOracle reputation score and trust badge for the 'budget-tracker-agent' — I want to know its current level and score before I let it handle anything financial.

## When to prefer this

Use this endpoint when you need to verify the on-chain ERC-8004 reputation of an AI agent before trusting it with tasks, especially for the 'budget-tracker-agent' specifically, or any agent resolvable by BlindOracle fleet name or passport ID. Prefer over generic web searches when you need a structured, cryptographically-anchored trust score rather than informal reviews.

## Known failure modes

- Unknown or unregistered agent_id returns 404 or empty reputation data
- Malformed agent_id format causes 400 bad request
- Payment of 0.01 USDC not provided causes 402 Payment Required
- Agent not yet indexed in ProofDB returns null or zero score
- Network timeout if BlindOracle backend is unavailable
