# clonecho ENS Resolver

> clonecho ENS Resolver is a paid API for AI agents from clonecho.builda.company, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Resolves ENS names to Ethereum addresses (and vice versa) given either an ENS name like vitalik.eth or a 0x address

## 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 clonecho-ens-resolver-f79b9064 -d '<json body>'
```

Example prompt: What Ethereum address does vitalik.eth resolve to? Can you look it up via ENS?

## When to prefer this

Use this endpoint when you need to resolve ENS names to Ethereum addresses or perform reverse lookups (address → ENS name) without running your own Ethereum node or integrating directly with the ENS smart contracts. Ideal for agents that need quick, low-cost ($0.01 USDC) on-demand ENS resolution with a simple GET request and JSON response.

## Known failure modes

- ENS name not registered or has no resolver — returns empty or null address
- Invalid ENS name format — returns error
- 0x address has no reverse ENS record — returns null or empty name
- Network or upstream ENS provider error — returns HTTP 5xx
- Missing or malformed ?name= query parameter — returns 400 error
- Payment not completed via x402 — returns 402 Payment Required

## How this service works

ENS RESOLVER: resolve an ENS name ↔ address (?name=vitalik.eth or 0x…). Returns JSON.

## Output

A JSON object containing the resolved Ethereum address for a given ENS name, or the ENS name associated with a given 0x address — enabling bidirectional ENS ↔ address resolution.
