## How to call it through Zero

```sh
zero fetch --capability quartermaster-basename-resolver-d9327662
```

Example prompt: What wallet address does jesse.base.eth resolve to on Base?

## When to prefer this

Use this endpoint when you need to resolve a human-readable .base.eth Basename to an on-chain wallet address on the Base L2 network. Prefer this over generic ENS resolvers when the name is specifically on Base (not mainnet ENS). Useful when building workflows that accept user-facing Basenames but need raw addresses for transactions.

## Known failure modes

- Basename not registered — returns null or 404 if the name has no on-chain record
- Missing 'name' query parameter — returns a 400 validation error
- Malformed or invalid basename string — may return an error or empty result
- Network/RPC issues with Base chain — service may be temporarily unavailable
- Payment failure (x402) — 402 response if USDC micropayment is not completed

## How this service works

Resolve Basenames (.base.eth) to wallet addresses on Base.

## Output

Returns the resolved wallet address (checksummed Ethereum address) associated with the provided .base.eth Basename on the Base network.
