## 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 beggar-bot-token-holders-endpoint-f9c43080
```

Example prompt: Who are the top 20 holders of the USDC token (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base mainnet over the last 500 blocks?

## When to prefer this

Use this endpoint when you need on-chain token holder rankings for ERC-20 tokens specifically on the Base network (mainnet or Sepolia testnet) and want a pay-per-call micropayment model via x402 without subscription overhead. Prefer this over general blockchain explorers when you need programmatic, agent-callable results with structured JSON output and configurable block windows.

## Known failure modes

- Invalid or non-existent ERC-20 token address returns an error or empty list
- Block window outside the allowed range (10–2000) may return a validation error
- Payment not provided or insufficient USDC results in HTTP 402 Payment Required
- Unsupported chain value returns an error
- Network congestion or RPC issues may cause timeouts or stale data

## How this service works

Paid: /v1/verify, /v1/risk, /v1/receipt cost $0.01 USDC per call on Base mainnet via x402 (payTo 0x719227f384b66BFEF00093D6d8d32fA9dC2B40e7); utilities analyze Base mainnet (USDC 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) by default, network=base-sepolia optional; /v1/receipt/verify and discovery files are free. Operator: Beggar Bot.

## Output

A JSON object listing the top N holders of the specified ERC-20 token on Base (or Base Sepolia), ranked by token balance, covering activity within the specified block window. Includes wallet addresses and their respective holdings, enabling concentration and whale analysis.
