## 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-insight-scam-check-owners-752b6178
```

Example prompt: Can you check if the NFT collection at contract address 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D on Ethereum is legit — I want to see the floor price, safelist status, who deployed it, and any scam signals.

## When to prefer this

Use this endpoint when you need a quick, affordable identity check on an NFT collection contract — especially to detect scams or verify OpenSea legitimacy before a purchase or interaction. Prefer this over on-chain-only tools when you need OpenSea floor price and safelist status in a single call. Best for ERC-721/ERC-1155 collection-level checks, not individual token metadata.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty result
- Unsupported chain identifier returns a validation error
- OpenSea data unavailable for very new or obscure collections
- Cache may return stale data up to 24 hours old
- Contract address on wrong chain returns no results or misleading data

## How this service works

Collection identity card (name, supply, deployer, OpenSea floor/safelist) — cached ≤24h

## Output

A JSON identity card for the NFT collection including: collection name, total token supply, deployer/creator wallet address, OpenSea floor price in ETH, OpenSea safelist status (verified/not), and derived scam/rug-pull risk signals. Data is cached for up to 24 hours.
