## How to call it through Zero

```sh
zero fetch --capability api-thetrustlayer-xyz-0960c021
```

Example prompt: Can you pull up all the agents registered under owner wallet 0xc15366b9c611d23dd1433c5f6782b2ab64457d03 on TrustLayer and show me their trust scores, which chains they're on, and any risk flags?

## When to prefer this

Use this endpoint when you need a comprehensive view of all agents operated by a specific wallet owner, including cross-chain coverage and trust/risk metadata. Prefer this over single-agent lookups when the user wants a portfolio-level view of an owner's AI agents rather than details on one specific agent address.

## Known failure modes

- Invalid or malformed wallet address returns 400 error
- Owner address with no registered agents returns empty agent list
- Large agent portfolios may be truncated (_truncated: true) requiring pagination
- Network or registry unavailability returns 5xx error
- Non-EVM non-Solana address formats may not be recognized

## How this service works

Reputation intelligence for the autonomous agent economy. Trust scores, Sybil detection, and cross-chain identity for 130,000+ ERC-8004 agents across 20 chains. Powered by x402 micropayments.

## Output

A JSON object listing all agents associated with the queried owner address, each with trust score (0-100), chain coverage, and risk assessment. The response includes a _truncated flag indicating whether the full list was cut off, plus summary metadata about the owner's agent portfolio.
