Guides
How token fraud works on AI platforms and how to stop it: free trial abuse, stolen API keys, the API relays that resell tokens and the accounts that supply them. Written for trust and safety teams.

How each kind of abuse works, what it costs and how to stop it, from the sources.
How AI platforms stop token resale and account sharing
A resold account looks like one customer and behaves like a hundred. This guide sets out the signals in your own logs that give it away, how to confirm resale without hurting real customers, and what to do once you find it.
How API relays resell cheap Claude and GPT tokens
Relays sell frontier models below list price because they rarely pay list price. The platform whose accounts, free credits and API keys fill the relay's pool pays the difference.
How to stop free trial abuse on an AI platform
Every free credit on an AI platform is compute someone pays for. Score each sign-up before it gets credits, stage the credits and keep the card for accounts that raise a signal.
How AI platforms detect ban evasion on new accounts
A ban removes an account, not the person or the setup behind it. On an AI platform the strongest evidence that they are back is how the new account uses your API.
Card testing and chargebacks on AI platforms
A stolen card that buys API credits costs you twice. The compute is spent as soon as the tokens are served, and the dispute arrives weeks or months later with a fee and a mark against your card network ratios. Here is how the pattern works and where to stop it.
How stolen API keys reach AI inference providers
Your customers' leaked keys end up in resale pools, and the traffic arrives under accounts you have every reason to trust. A platform can find many leaks first, notice when a key changes hands and cap what a stolen key can spend.
Stripe Radar covers payments. AI platforms still need usage fraud detection
Most AI companies already run Stripe, so the question is what Radar covers and what is left. Radar is strong on payments and, on its Pro plan, now scores trials, sign-ups and logins. It has little to go on once an approved account starts calling your API.
