## 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-7cec6c1b
```

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 vice versa) as part of a blockchain workflow, wallet lookup, or identity verification task. Prefer it over generic RPC calls when you want a pay-per-request, infrastructure-free resolution with no node setup required. Ideal for agents handling Web3 identity, address book enrichment, or DeFi transaction routing.

## Known failure modes

- ENS name not registered or has expired — returns not found or null
- Ethereum address has no reverse ENS record — returns empty result
- Invalid ENS name format or malformed 0x address — returns 400 validation error
- ENS resolver contract unreachable or chain RPC outage — returns 503 or timeout
- Payment not attached or insufficient USDC — returns 402 payment required

## How this service works

The most complete blockchain data and intelligence service for AI agents. 93 endpoints across 46 chains, from gas fees to DeFi analytics, with real-time streams, intent routing, and verifiable proofs. Pay-per-request via x402.

## Output

Returns the resolved Ethereum address for a given ENS name, or the ENS domain name associated with a given Ethereum address, based on on-chain ENS registry data.
