This page is designed to help you find out whether SignupVet is good and if it is the right choice for you.
SignupVet keeps your free credits and trials for real users, not bots. It is a signup-fraud API for SaaS and AI products that give away free trials or credits. One call checks the email (disposable and typo domains, missing mail servers), the phone number (validity, line type) and the IP (Tor, VPNs, datacenters, country), and spots bursts of signups from the same network or email pattern. It returns a 0–100 risk score, a decision (allow, review or block) and readable reason codes. Personal data is stored only masked, and logs are deleted after 90 days. Free plan with 250 checks a month, paid plans from $49 a month, and prepaid packs of 1,000 checks for $15 without a subscription. Live demo on the homepage, no signup needed.

SignupVet looks at the whole signup, not one field at a time. One API call checks the email, phone number and IP together and compares the new signup with your recent ones, so it can spot waves: many signups from one IP or network, or generated address series like max1, max2, max3 on the same domain. Every result comes with readable reason codes, so you can see why a signup was flagged.
Choose it if you give away free credits or trials and want one simple check at signup: one call instead of separate email, phone and IP services, a free plan with 250 checks a month and no card, and prepaid packs of 1,000 checks for $15 if you don't want a subscription. Personal data is stored only masked, and logs are deleted after 90 days. It is not a list-cleaning or inbox-verification tool; if that is what you need, a dedicated email verifier is a better fit.
SignupVet started from a simple problem: products with free credits or trials attract fake signups, and every fake account uses the same compute as a real user. We built one API that checks the email, phone and IP of a new signup together and tells you whether to allow, review or block it, with a free plan so small teams can start right away.
Founders and developers of small SaaS and AI products that give away free credits or free trials and lose money when bots or repeat users create fake accounts to use them.
