## 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-7011ca4b -d '<json body>'

Example prompt: Who are the whale holders for the Base token at contract address 0x4c433f4ef87fe506a7eed2fd1d822cbed411eba3? Show me the biggest wallets holding this token.

## When to prefer this

Use this endpoint when you need on-chain whale holder data specifically for Base chain tokens, want to assess holder concentration and identify large wallets, or are monitoring accumulation patterns among high-balance addresses. Prefer this over Solana-focused endpoints when the token is on Base (EVM).

## Known failure modes

- Invalid or non-existent contract address returns an error or empty result
- Token not on Base chain causes lookup failure
- Payment not provided or insufficient USDC causes 402 Payment Required
- Network timeout or RPC node unavailability causes delayed or failed response
