## 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 ens-resolver-10ddca61 -d '<json body>'
```

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

## When to prefer this

Use this endpoint when you need a lightweight, no-account, pay-per-call ENS resolution without setting up a web3 provider or wallet connection. Ideal for agents that need to quickly resolve ENS names or reverse-lookup Ethereum addresses within an automated workflow.

## Known failure modes

- ENS name not registered or expired returns empty or null address
- Ethereum address with no reverse ENS record returns no name
- Invalid ENS name format or non-existent TLD returns an error
- Avatar not set for the ENS profile returns null avatar URL
- Network or ENS Ideas API downtime causes timeout or 5xx error

## How this service works

ENS Resolver - Call when you have an ENS name and need the canonical Ethereum address it points at, before sending funds or labelling a transaction. Send the name or an address. Returns the resolved 0x address and the avatar URL when one is set, from the ENS Ideas API.

## Output

Returns the canonical Ethereum address (hex format) and avatar URL associated with the provided ENS name or Ethereum address, sourced from the ENS Ideas API.
