Example use cases
Audit counterparty NFT wallet safety
“Before I accept this NFT trade from wallet 0xDef456...abc on Ethereum, can you check their holdings and let me know if they have any flagged scam or spam collections in their portfolio?”
Screen wallet for rug pulls
“I'm about to send crypto to 0x789Xyz...321 — can you pull up their NFT portfolio on Polygon and flag anything that looks like a rug pull, phishing token, or fake collection?”
Summarize NFT collection breakdown
“Can you give me a full breakdown of all the NFT collections owned by wallet 0xAaB123...999 on Ethereum, showing how many tokens they hold from each collection and whether any of them are marked as suspicious?”
Technical details
Endpoint
GEThttps://x402.professorsausages.com/nft/:chain/wallet/:address/collectionsWhen to prefer
Use this endpoint when you need a rolled-up, per-collection view of a wallet's NFT holdings with built-in spam/scam flagging. It is ideal for portfolio audits, due diligence on counterparties, or screening wallets before accepting NFT transfers. Prefer it over raw on-chain queries when you want pre-aggregated data with safety signals without building your own scam detection logic.
Side effects
- Invalid or malformed wallet address returns an error
- Unsupported chain identifier returns a 400 or not-found error
- Wallet with no NFTs returns an empty collection list
- Cache miss on a new address may cause slightly longer response
- Rate limit or payment failure returns a 402 or 429 error
