## 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 token-holders-analysis-api-39c0d32e
```

Example prompt: Can you analyze the holder distribution and concentration metrics for the token at contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum?

## When to prefer this

Use this endpoint when you need on-chain token holder concentration data for a specific ERC-20 token on Ethereum or Base, particularly to assess ownership distribution, identify whale concentration risk, or evaluate decentralization of a token's supply.

## Known failure modes

- Invalid or non-existent contract address returns error or empty result
- Unsupported chain value returns validation error
- Token with no indexed holders may return empty dataset
- Rate limiting or payment failure may result in 402 response
- Network-specific addresses queried on wrong chain return no data

## How this service works

Get token holder analysis with concentration metrics (POST variant)

## Output

Returns token holder analysis including list of holding addresses, their balances, concentration metrics such as top-holder percentage share, Gini coefficient or similar distribution indicators, and total holder count for the specified token contract.
