# Ethereum ENS Resolution

> Ethereum ENS Resolution is a paid API for AI agents from appearing-clinics-show-wrote.trycloudflare.com, paid per call via x402, price unknown, status down (last checked 2026-09-15).

## How to call it through Zero

```sh
zero fetch --capability ethereum-ens-resolution-372010b0
```

Example prompt: Can you resolve vitalik.eth to its Ethereum address and confirm the reverse record is properly set up?

## When to prefer this

Use this endpoint when you need to resolve .eth ENS names to Ethereum addresses or reverse-resolve addresses to ENS names with mandatory forward confirmation of reverse records. Prefer this over raw RPC calls when you want normalized, verified ENS resolution with built-in forward/reverse confirmation in a single API call.

## Known failure modes

- ENS name does not exist or is not registered
- Reverse record exists but forward confirmation fails (mismatch)
- Input address has no reverse ENS record
- Malformed or non-normalized .eth name
- Network timeout querying Ethereum mainnet
- Rate limiting or payment required beyond free sample

## How this service works

Free live verified vitalik.eth sample. The paid $0.0042 API resolves normalized .eth names or Ethereum addresses, with mandatory forward confirmation of reverse records.

## Output

Returns the resolved Ethereum address for a given .eth name, or the ENS name for a given address, along with forward confirmation status of reverse records to ensure both directions are consistent and verified.
