## 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 citiview-ens-basenames-resolver-347c8fb6
```

Example prompt: Can you look up vitalik.eth and tell me the wallet address it resolves to, along with any avatar or Twitter profile records attached to it?

## When to prefer this

Choose this endpoint when you need to resolve ENS names (*.eth) or Basenames (*.base.eth) to wallet addresses, or reverse-resolve a 0x Ethereum address to its human-readable name, especially when you also need profile metadata like avatar, Twitter, or description records in a single call. Prefer this over on-chain RPC calls when you want a simple REST API with profile enrichment included.

## Known failure modes

- Name not registered or expired — no address returned
- 0x address has no primary name set — reverse lookup returns null
- Malformed query string (missing 'q' param) — 400 error
- ENS subgraph or resolver temporarily unavailable — 503 or timeout
- Non-existent Basename on Base chain — empty or null result

## How this service works

Crypto name lookup: resolve ENS and Basenames (vitalik.eth, jesse.base.eth) to a wallet address with avatar, url, twitter and description records, or reverse-resolve a 0x address to its primary name.

## Output

Returns the resolved wallet address plus available profile records including avatar image URL, website URL, Twitter/X handle, and text description for a given ENS or Basename. For reverse lookups, returns the primary ENS or Basename assigned to the 0x address.
