## 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 8k4-protocol-resolve-agent-identities-by-wallet-0e9fcf02
```

Example prompt: Can you look up all the ERC-8004 agents registered to wallet 0xAbC123...def456 and tell me their agent IDs and which chains they're on?

## When to prefer this

Use this endpoint when you need to enumerate all ERC-8004 agent identities associated with a specific wallet address, particularly as a starting point before fetching trust scores or metadata for individual agents. Prefer this over agent-specific endpoints when the agent_id is unknown and only the wallet is available.

## Known failure modes

- Wallet address not found — returns empty array or 404
- Malformed wallet address — returns 400 bad request
- No agents registered to wallet — returns empty array
- Service unavailable — returns 5xx error
- Rate limit exceeded — returns 429

## How this service works

## Output

Returns a JSON array of agent registration records, each containing the wallet address, agent_id (numeric), chain (e.g. 'base'), and created_at timestamp. Represents every ERC-8004 agent identity associated with the queried wallet.
