## 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 trustlayer-agent-profile-lookup-66b3c126
```

Example prompt: Can you pull up the TrustLayer trust score and full profile breakdown for the agent at base:0x13b1e9b460557417dcf97ce75fce5674423d573f? I want to see its component scores, feedback counts, and metadata before I decide whether to interact with it.

## When to prefer this

Use this endpoint when you need to assess the trustworthiness or reputation of a specific ERC-8004 registered autonomous agent on a supported chain (e.g. Base) before interacting with, delegating to, or transacting with it. Prefer this over the time-series endpoint when you only need the current snapshot rather than historical trajectory.

## Known failure modes

- Agent ID not found or not indexed — returns 404 or empty result
- Malformed agentId format (missing chain prefix or invalid address) — returns 400 validation error
- Payment not included or insufficient — returns 402 Payment Required
- Network or rate-limit issues — returns 429 or 503
- Agent exists on a chain not yet supported — may return empty or partial data

## How this service works

Agent profile lookup. Returns trust score, component breakdown, feedback counts, and metadata for any ERC-8004 agent.

## Output

Returns a trust score (0–100), a breakdown of score components, feedback/review counts, and descriptive metadata for the queried ERC-8004 agent on the specified chain.
