Fidro vs Abstract API
Abstract API checks whether an email address is real and deliverable. Fidro checks whether the person behind it is, using the email, the IP and the network together, and tells your code to allow, challenge or block.
What is Fidro?
Fidro is a fraud detection API for developers. One call checks an email address and an IP for disposable domains, VPNs, proxies, Tor and datacenters, remembers earlier signups and logins, and returns a 0 to 100 risk score with an allow, challenge or block recommendation. On the Pro plan it also scores Stripe payments. The free plan includes 200 validations a month, no credit card needed.

Where Fidro differs from Abstract API
More than the email
Abstract API checks the email. Fidro checks the email, the IP, the network and the location in the same call, and remembers what it has seen before.
A decision, not a data point
Every call returns a score from 0 to 100 and allow, challenge or block, with the reasons. Your code acts on one field instead of building its own scoring.
