## 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 vextorium-ens-profile-lookup-df31ecd6 -d '<json body>'
```

Example prompt: Can you look up the ENS profile for vitalik.eth and tell me the linked Ethereum address, Twitter handle, and any other public records?

## When to prefer this

Use this endpoint when you need to resolve a .eth ENS name to an Ethereum address and/or retrieve the social and profile metadata voluntarily published by the ENS holder. Prefer this over raw on-chain lookups when you want a clean, structured JSON response including all standard text records in one call. Ideal for enriching Web3 user profiles, verifying identity context, or finding contact handles for a known ENS name.

## Known failure modes

- ENS name not found or unregistered — returns null address and empty records
- ENS name has no resolver set — cannot retrieve records
- Network/RPC issues resolving ENS on-chain — timeout or service error
- Malformed ENS name input (missing .eth suffix or invalid characters) — validation error
- Records exist on-chain but are stale or the name has expired — may return outdated data

## How this service works

558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.

## Output

A JSON object containing the resolved Ethereum address (checksummed), the ENS name, and a records object with available text fields: avatar (URL), description, url (website), com.twitter, com.github, and potentially telegram, discord, email. Fields not set by the holder are returned as null. A note clarifies data is voluntarily published by the holder on ENS.
