Example prompt: Can you scan the NFT contract 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13d on Ethereum for wash trading over the last 7 days and tell me if the volume looks artificially inflated?

## When to prefer this

Use this endpoint when you need real-time, on-chain wash trade detection specifically for NFTs — particularly when evaluating a collection before investment, auditing marketplace listings, or building NFT analytics dashboards that surface manipulation risk. Prefer this over general blockchain analytics tools when the specific concern is circular trading and artificial volume inflation in the NFT market.

## Known failure modes

- Invalid or unrecognized contract address returns an error
- Unsupported blockchain identifier causes a 400-level error
- Contract with no trading history in the selected time window may return empty results
- Token ID not found within the contract returns a not-found error
- Malformed request missing required fields (chain or contractAddress) returns a validation error

## How this service works
