## 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 api-web3identity-com-8f705948
```

Example prompt: What Ethereum address and records are linked to ethereum.eth — can you resolve that ENS name for me?

## When to prefer this

Use this endpoint when you need to resolve a human-readable .eth ENS name to its underlying Ethereum address or retrieve associated ENS profile records. Prefer this over generic blockchain RPC calls when you want a simple HTTP API that handles ENS resolution without managing node connections.

## Known failure modes

- ENS name not registered or expired — returns null or empty address
- Invalid ENS name format — returns 400 or validation error
- ENS name has no records set — returns address only with empty records
- Ethereum node or ENS contract unavailable — returns 503 or timeout
- Name contains unsupported characters — returns error response
