How this service works
Device-fingerprint resale fraud check: submit a browser or device fingerprint and receive a risk signal showing whether that fingerprint has been resold or reused across many accounts — a strong indicator of account-takeover, bonus abuse, fake-account farming, and bot networks. Returns a fraud score, match count, and first/last-seen timestamps. Strengthens KYC, signup, and login defenses. (Paused pending API key; indexing resumes after first settled call.)
Output
Returns a resell risk assessment for the given request ID, likely including a risk flag or score indicating whether the fingerprinted request exhibits resell or scalping behavior.
Example use cases
Catch scalper bots at checkout
“We're launching limited-edition sneakers tomorrow and I'm worried about bots. Can you check request ID 'req-98712-boot' against the fingerprint resell risk API to see if this buyer looks like a scalper before we let the purchase go through?”
Flag fake accounts during signup
“We've had a wave of suspicious new account registrations this week. Can you run a fingerprint resell risk check on request ID 'reg-55423-usr' to find out if this device fingerprint has been reused across multiple accounts and whether it's flagged as high risk?”
Detect bonus abuse on promotions
“A user just claimed our referral bonus for the third time this month using what looks like a different account. Can you check request ID 'promo-77301-clm' through the fingerprint resell risk service to see if the fingerprint has been seen before and if there's any fraud signal we should act on?”
