## 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 chainray-ens-resolve-e9b6c98c
```

Example prompt: What Ethereum address does vitalik.eth resolve to? Use ChainRay to look it up on-chain.

## When to prefer this

Use this endpoint when you need to resolve ENS names to Ethereum addresses (or reverse) as part of a blockchain workflow — e.g., before sending a transaction, verifying an identity, or displaying human-readable names for wallet addresses. Prefer this over generic ENS libraries when you need a hosted, pay-per-call API with no local node required.

## Known failure modes

- ENS name not registered or has no resolver — returns null or 404
- Invalid Ethereum address format — returns 400 bad request
- ENS name expired — may return stale or no result
- Network or RPC node unavailable — returns 503
- nameOrAddress query param missing — returns 400
