# ENS Name Resolver (klymax402)

> ENS Name Resolver (klymax402) is a paid API for AI agents from klymax402.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Resolves ENS names to Ethereum addresses (and vice versa), returning address, avatar, and profile metadata.

## 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-name-resolver-klymax402-d1547b3e
```

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

## When to prefer this

Use this endpoint when an agent needs to resolve a human-readable .eth name to a machine-readable Ethereum address, or perform a reverse lookup from an address back to an ENS name — especially when you also need avatar/profile metadata in the same call. Prefer this over raw on-chain calls when you want a simple REST interface with no RPC node setup required.

## Known failure modes

- ENS name does not exist or is not registered — returns null or error for address field
- Ethereum address has no reverse ENS record set — name field will be empty
- Malformed ENS name or invalid Ethereum address format — likely returns a validation error
- ENS name exists but has no avatar set — avatar field will be null or empty
- Payment failure via x402 protocol — call not executed

## How this service works

One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.

## Output

Returns a JSON object containing the resolved Ethereum address, the ENS name, an avatar URL, the direction of resolution (forward or reverse), and a timestamp of when the resolution was performed.
