Frequently Asked Questions

What is the difference between Fidro and VPNAPI.io?
VPNAPI.io is a specialist: it takes an IP address and tells you whether it is a VPN, proxy or Tor node. Fidro checks the same network signals but also validates the email address, checks it against 50,000+ disposable domains, compares stated country against IP geolocation, and combines everything into one risk score with an allow, review or block recommendation. VPNAPI.io returns flags you interpret; Fidro returns a decision.
Does VPNAPI.io have a more generous free tier than Fidro?
Yes, considerably. VPNAPI.io allows 1,000 API requests per day on its free plan, which resets at 00:00 UTC, roughly 30,000 a month. Fidro's free plan is 200 validations a month. If you only need IP lookups at volume and you are cost-sensitive, VPNAPI.io is the better free option and we would rather tell you that here.
Should I use VPNAPI.io or Fidro?
Use VPNAPI.io if you need one signal, at volume, cheaply, and you are happy writing the scoring logic yourself. Use Fidro if you want the network signal weighed alongside email and location risk and returned as a decision, or if you also need to score payments. Many teams start with a single-signal API and move when maintaining their own scoring logic across two or three vendors becomes the work.
Can Fidro replace VPNAPI.io?
For fraud prevention use cases, yes: Fidro covers VPN, proxy, Tor and datacenter detection in the same call as its email and geolocation checks. If your use case is purely high-volume IP classification with no fraud decision attached, VPNAPI.io is the more focused and cheaper tool for that job.
Does VPNAPI.io detect disposable email addresses?
No. VPNAPI.io works on IP addresses only. Disposable email detection would require a separate email validation vendor alongside it, which is the stack Fidro is designed to replace with a single call.
