AI software is under attack. Stop AI token fraud.
Protect your AI platform from fake accounts, stolen API keys, credit abuse, and fraudulent payments. Sardine identifies the devices, identities, and networks behind the attacks before they drain your resources.
AI tokens have value and fraudsters are cashing in
Free credits, API keys, and model access have become targets for fraud. Attackers exploit promotional offers, compromise legitimate accounts, and resell discounted AI access, leaving platforms to absorb the costs.
Free credits fuel account farming
Fraudsters create fake accounts at volume to claim free credits and referral rewards, draining resources intended to attract legitimate users.
Stolen API keys drive up costs
Compromised credentials give attackers unauthorized access to models, generating compute expenses that can go undetected.
Reseller networks obscure abuse
Fraudulent businesses and intermediaries disguise who is accessing models, making coordinated abuse harder to detect.
Uncover the fraud behind AI token abuse
Sardine connects device, identity, behavioral, and payment intelligence to detect coordinated attacks, uncover hidden networks, and protect your platform from costly abuse.
Stop token fraud wherever it starts
Identify the abuse behind fraudulent accounts, stolen credentials, unauthorized usage, and payment losses.
Promo and sign-up abuse
Stop automated sign-ups from draining free trials, referral bonuses, and startup credits. Device fingerprints, email and phone enrichment, and behavioral signals show when one person is behind many accounts.

Catch stolen credentials before they become unauthorized usage. Sardine flags risky logins and new devices around key creation and use.
Learn moreToken and credit reselling
Keep credits and grants from being collected and sold at a discount. Business verification screens applicants, and shared payment methods expose resellers.
Learn moreFraudulent token purchases
Block stolen cards on top-ups before the chargeback arrives. Models score every card-not-present payment, with ACH and other methods as platforms add them.
Learn moreCoordinated account networks
Expose networks of accounts that query your models at volume to copy them. Shared devices, proxies, and payment methods link the accounts into one network.

Go past bots to uncover the fraud driving AI token abuse
Bot checks alone miss coordinated abuse. Sardine combines device intelligence, network-wide fraud signals, and real-time controls to uncover the fraud behind it.
Detect fraud that gets past bot defenses
Go beyond basic bot checks with device fingerprinting, proxy intelligence, and network signals. Identify suspicious devices even as attackers change accounts or hide their activity.
Uncover fraud networks not just accounts
Connect accounts, devices, identities, and payment methods to expose coordinated attacks. Leverage Sardine’s network intelligence to detect risk beyond your platform.
Protect more than the first sign-up
Monitor risk across onboarding, payments, and ongoing account activity. Investigate emerging threats and adapt fraud controls as attackers change tactics.
