Example use cases
Example prompt
“Can you run a risk assessment on the Azuki NFT collection at contract address 0xED5AF388653567Af2F388E6224dC7C4b3241C544 on Ethereum — I want to know if there's wash trading happening and whether the holder distribution looks healthy before I consider buying.”
Technical details
Endpoint
POSThttps://defi-shield-hazel.vercel.app/api/nft/collection-riskWhen to prefer
Use this endpoint when you need a combined wash-trading and holder-distribution risk signal for an NFT collection in a single call, particularly for due diligence before an NFT purchase or investment decision. Prefer this over generic on-chain analytics when you want a pre-computed risk score rather than raw transaction data.
Side effects
- Invalid or unrecognized contract address returns an error
- Collection not indexed or too new returns insufficient data error
- Unsupported blockchain network returns unsupported chain error
- Rate limiting or payment failure returns 402 or 429 status
- Network RPC unavailability causes timeout or partial data response
