## How to call it through Zero

```

Example prompt: Can you run a scam check on the NFT collection at contract address 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13d on Ethereum and tell me if it's flagged for spam, copymint collisions, or suspicious ownership concentration?

## When to prefer this

Use this endpoint when you need a fast, deterministic, evidence-backed scam verdict on a specific NFT collection before a user purchases or interacts with it. Prefer this over generic token safety checks when the asset is an NFT (ERC-721/ERC-1155) rather than an ERC-20 fungible token. The cached results (≤24h) make it cost-effective for repeated checks on the same collection.

## Known failure modes

- Invalid or unsupported chain identifier — endpoint returns error indicating chain is not supported
- Contract address not found on the specified chain — returns not-found or empty result
- Malformed contract address format — returns validation error
- Rate limiting or payment failure — returns 402 or 429 status
- Upstream blockchain node timeout causing incomplete analysis

## How this service works

Deterministic scam checklist with verdict + evidence (spam flags, copymint collision, concentration) — cached ≤24h

## Output

Returns a deterministic scam verdict (pass/fail) with supporting evidence: spam flags, copymint collision matches against known legitimate collections, and ownership concentration metrics indicating whale or wash-trading risk. Results are cached for up to 24 hours.
