## 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 x402-chain-intel-holder-concentration-b91aabdd -d '<json body>'
```

Example prompt: What's the holder concentration for the token at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum — I want to know what percentage of supply the top wallets control before I place a trade.

## When to prefer this

Choose this endpoint when you need on-chain holder concentration data specifically for trading bot decision-making, risk scoring, or whale detection — particularly when you need a paid, reliable signal with x402 micropayment access rather than scraping free explorers. Prefer this over generic block explorers when you need structured, machine-readable concentration metrics ready for algorithmic consumption.

## Known failure modes

- Invalid or unrecognized contract address returns an error or empty result
- Unsupported blockchain network causes a 400 or 422 error
- Token with very low holder count may return incomplete distribution data
- Payment of 0.14 USDC not fulfilled causes 402 Payment Required
- Rate limiting or provider downtime returns 429 or 503
- Newly deployed contracts with no indexed holder data may return null metrics
