## 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 blockscout-bens-batch-resolve-addresses-d95acab1 -d '<json body>'
```

Example prompt: Can you resolve these wallet addresses to their human-readable names using Blockscout — 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045, 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B, and 0x71C7656EC7ab88b098defB751B7401B5f6d8976F?

## When to prefer this

Use this endpoint when you need to resolve multiple blockchain addresses to human-readable names in a single API call rather than one at a time. Prefer it over single-address lookups when enriching lists of addresses, displaying wallet holders, or annotating transaction history with names across multiple chains via Blockscout's unified name service index.

## Known failure modes

- Empty names map returned if none of the input addresses have registered names
- Invalid address format causes validation error
- Too many addresses in a single batch may result in a timeout or error
- Network or chain unavailability may prevent resolution for some addresses
- Payment failure (402) if x402 micropayment is not properly included

## Output

Returns a map (names object) of input addresses to their resolved human-readable names (e.g. ENS names or other blockchain name service labels). Addresses without registered names may return empty or null entries.
