Free credits are for users, not for credit farms.
On an AI product every free account spends real GPU money. Attrelix checks each signup before you grant credits, so scripts and account farms get stamped and real users get through.
One script tag and one server call. No card to start.
Why AI apps are a target
Free credits on an AI product can be resold or used to run someone else's workload. Farms create hundreds of accounts with scripts, rotate inboxes and run from cloud servers, and each account spends tokens you pay for.
Rate limits per account do not help when the accounts are new. You need to decide at signup, before the credits are granted.
Signals that expose a credit farm
Automation and anti-detect browsers
Headless Chromium, WebDriver and DevTools-protocol automation, plus browsers whose fingerprint contradicts itself, the trace of anti-detect tools.
Cloud and Tor traffic
Signups from AWS, Google Cloud, Oracle, DigitalOcean, Linode and Tor exits, and how many accounts one address or subnet created today.
Accounts that belong together
Shared devices, shared card fingerprints and one mailbox written many ways are counted as one cluster, so you see the farm, not single rows.
Questions
Where in my signup flow do I call it?
Call /v1/check from your server after the account form is submitted and before you grant free credits. The answer is allow, review or block, with reasons.
What should I do on review?
Common choices: grant fewer credits, ask for a card or phone number, or hold credits until the e-mail is verified. Attrelix returns the decision, your product chooses the consequence.
Can I see how much the abuse costs?
Yes. Enter the value of the free credits a new account receives and the dashboard estimates the credits kept from flagged accounts.
What does it cost?
1,000 checks a month are free with no card. Paid plans start at $29 a month for 10,000 checks.
