## 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-insight-scam-check-owners-ad673c70
```

Example prompt: Can you check whether the NFT at contract address 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13d token ID 1234 on Ethereum is a scam or spam, and tell me who owns it and whether the metadata storage is durable?

## When to prefer this

Use this endpoint when you need a quick, single-asset NFT safety check covering ownership, metadata durability, image validity, and spam/scam signals on EVM chains. Prefer this over generic blockchain explorers when you need consolidated health signals rather than raw on-chain data, and when a cached result within 24 hours is acceptable.

## Known failure modes

- Invalid or unsupported chain identifier returns an error
- Contract address not found or not an NFT contract
- Token ID does not exist on the contract
- Metadata IPFS/Arweave node unreachable causing partial results
- Rate limit or payment failure returns 402

## How this service works

Single-asset health: owner, metadata storage durability, image, spam inheritance — cached ≤24h

## Output

Returns a health report for a single NFT including: current owner address, metadata storage type and durability assessment, image URL reachability, spam/scam inheritance flags derived from contract behavior, and an overall health verdict — data cached up to 24 hours
