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.
Example use cases
Verify NFT before purchase
“I'm about to buy an NFT from the collection at 0x49cF6f5d44E70224e2E23fDcdd2C053F30aDA28b — can you run a scam check on it first and let me know if it passes, if there are any spam flags, or if it looks like a copycat mint of a legit project?”
Detect rug pull risk
“I've heard some rumors that the NFT project at contract 0x60E4d786628Fea6478F785A6d7e704777c86a7c6 on Ethereum might be a rug pull — can you check it for suspicious ownership concentration, wash trading signals, or any other red flags before I recommend it to anyone?”
Authenticate NFT collection legitimacy
“Someone just sent me a link to an NFT collection claiming to be an official drop from a well-known brand, the contract is 0xb47e3cd837dDF8e4c57F05d70Ab865de6e193BBB — can you verify whether it's a legitimate project or a copymint impersonating something else?”
Technical details
Endpoint
GEThttps://x402.professorsausages.com/nft/:chain/collection/:address/scam-check?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| chainrequired | string | Which chain the address belongs to. base and ethereum run full on-chain mode; the rest are list-only mode. |
| addressrequired | string | The address in that chain's native format (0x… for EVM, base58/bech32 otherwise). Checked against that chain's shape BEFORE the payment gate — a malformed address is a free 400, never a 402. |
