## 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 base-basename-resolver-67978eb9
```

Example prompt: What wallet address does the Base basename 'alice.base.eth' resolve to? I need the 0x address so I can send her a payment.

## When to prefer this

Use this endpoint when you need to resolve a human-readable Base Basename (e.g. alice.base.eth) to a wallet address on Base mainnet. Prefer this over generic ENS resolvers when the name is specifically a Base Basename (Base's native L2 naming system), not a mainnet ENS name. Ideal before sending payments, whitelisting addresses, or verifying identities tied to Base names.

## Known failure modes

- Basename not registered or does not exist — resolver returns null or zero address
- Invalid or malformed name input — may return an error or empty result
- Basename registered but no address set — resolver returns zero address
- Network or RPC timeout causing failed resolution
- Name without .base.eth suffix may fail to resolve if suffix is required

## How this service works

Resolve a Basename, Base's native ENS-equivalent, to its wallet address via the L2 Basenames resolver.

## Output

Returns the resolved wallet address (0x-prefixed Ethereum address) associated with the given Base Basename, fetched via the L2 Basenames resolver contract on Base mainnet.
