## How to call it through Zero

```sh
zero fetch --capability saylor-innovations-ens-resolver-42d79470
```

Example prompt: What Ethereum address does vitalik.eth resolve to on-chain?

## When to prefer this

Choose this endpoint when you need a live, on-chain ENS resolution for Ethereum mainnet and want a simple REST call rather than integrating an Ethereum node or ethers.js library directly. Ideal for agents that need to translate human-readable .eth names to wallet addresses before executing transactions or displaying identity information.

## Known failure modes

- ENS name not registered — returns null or not-found error
- ENS name expired — may return stale or no address
- Network/RPC error reaching Ethereum node
- Malformed ENS name input (e.g. missing .eth suffix or invalid characters)
- Name registered but no address record set — returns empty resolver

## How this service works

ENS Resolve (ethereum) — On-Chain Data

## Output

Returns the resolved Ethereum address (and potentially other ENS records such as resolver, content hash, or text records) associated with the provided ENS name, fetched directly from the Ethereum blockchain.
