## 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 mpp-hyreagent-fun-eb35fdb7 -d '<json body>'
```

Example prompt: Who are the whale holders of the Base token at contract address 0x4c433F4EF87fE506A7eED2fD1d822CBED411eBA3? I want to see which large wallets are holding the most.

## When to prefer this

Use this endpoint when you need to identify large token holders (whales) for a specific Base chain token by contract address. Prefer this over general holder analytics when you specifically want whale-level concentration data on the Base network.

## Known failure modes

- Invalid or non-existent token contract address returns empty or error response
- Token not deployed on Base chain returns no results
- Network congestion or RPC errors cause timeouts
- Payment not received or insufficient USDC causes 402 rejection
