Technical details
Endpoint
GEThttps://x402.professorsausages.com/nft/:chain/collection/:address/wash-checkWhen to prefer
Use this endpoint when you need a fast, structured wash-trade risk signal for a specific NFT collection on EVM chains, particularly when you want per-rule breakdown rather than a single opaque score. Prefer this over manual inspection or generic token checks when evaluating NFT project legitimacy before a purchase or listing decision.
Side effects
- Invalid or unrecognized chain identifier returns an error
- Contract address not found or not an NFT collection returns empty or error
- Collection has fewer than the minimum required sales for meaningful analysis
- Rate limits or upstream RPC failures cause timeout
- Payment not fulfilled results in 402 response
