## 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-9917a132
```

Example prompt: What Ethereum wallet address does coinbase.eth resolve to, and can you also pull back any text records attached to it?

## When to prefer this

Use this endpoint when you need to programmatically resolve a human-readable ENS name (e.g. coinbase.eth) to its canonical Ethereum address or retrieve its on-chain records. Prefer this over manual RPC calls when you need a simple REST interface to ENS resolution with aggregated records support.

## Known failure modes

- ENS name not registered — returns null or 404
- ENS name expired — may return stale or no address
- Resolver not set for the ENS name — partial or empty records
- Invalid ENS name format — validation error
- Network timeout reaching ENS resolver contracts
- ENS name has no address record set — returns empty address field

## How this service works

Resolve ENS name to address and records

## Output

Returns the resolved Ethereum address (0x...) for the given ENS name along with associated on-chain records such as text records, content hash, and other resolver data stored under that ENS domain.

## Example request

```json
{
 "name": "vitalik.eth"
}
