## 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 agentrep-ai-agent-reputation-profile-query-82f2d014
```

Example prompt: Can you check the AgentRep reputation profile for the agent with ID 'my-agent-v1' and tell me its trust score, grade, and whether it's considered trustworthy?

## When to prefer this

Use this endpoint when an AI agent or orchestrator needs to verify the trustworthiness of another agent before delegating tasks, sharing data, or entering into an automated interaction. Prefer this over manual whitelists or custom trust logic when you want a network-sourced, community-endorsed reputation signal. Best suited for agent-to-agent trust checks in agentic pipelines where paying $0.001 USDC per query is acceptable.

## Known failure modes

- Unknown or unregistered agent_id returns no profile or a 404-equivalent
- Payment failure (x402) if USDC balance is insufficient or wallet not configured — returns 402 Payment Required
- Rate limiting if too many queries in a short period
- Malformed agent_id returns a validation error
- Network or service downtime returns 5xx error
