## 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 nft-collection-stats-scam-check-owner-concentration-80623596
```

Example prompt: Can you pull the collection stats for the NFT contract 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13d on Ethereum — I want to know the total supply, how many unique owners there are, whether the top 10 wallets hold a suspicious chunk, and what the floor price looks like across marketplaces?

## When to prefer this

Use this endpoint when you need a quick, affordable ($0.005) snapshot of an NFT collection's health, ownership distribution, and cross-marketplace floor prices — especially for scam/rug-pull detection based on holder concentration. Prefer this over on-chain RPC calls when you want aggregated multi-marketplace data without building your own indexer. Best for due diligence on unfamiliar collections before purchasing.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty result
- Unsupported chain identifier causes a bad request response
- Collection too new or illiquid — floor price data may be absent or stale
- Rate limiting or payment failure if x402 payment not properly handled
- Cached data up to 24h old may not reflect very recent trades or mints
