## 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 saylor-innovations-ens-resolve-ethereum-9937d7d3
```

Example prompt: What Ethereum address does vitalik.eth resolve to, and does it have an ENS avatar set?

## When to prefer this

Use this endpoint when you need to resolve ENS .eth names to Ethereum addresses (or vice versa) including avatar retrieval, without running your own Ethereum node or ENS library. Ideal for agents building Web3 identity features, payment address verification, or displaying human-readable names alongside wallet addresses.

## Known failure modes

- ENS name not registered returns null address
- Address has no primary ENS name set returns null name
- Invalid .eth name format may return null or error
- Avatar not set returns null avatar
- Network or RPC issues may cause transient failures
