In one sentence: Abstract API gives you many separate utility APIs; Veqen focuses on signups and joins email, IP and phone into one decision.
How they differ
| Abstract API | Veqen | |
|---|---|---|
| Model | Separate APIs (email validation, IP geolocation, phone validation and many more) | One API focused on signup risk, with individual checks too |
| Combined verdict | Combine results yourself | /v1/signup/check returns one score, verdict and reasons |
| Cross-checks | — | Phone country vs IP country, throwaway inbox from a server, and more |
| Billing | See their pricing page | Prepaid credits across all checks, 1,000 free per month, never expire |
When to choose Abstract API
If you need utilities beyond fraud, like exchange rates, holidays or screenshots, from one vendor, a broad utility catalog is convenient.
When to choose Veqen
If your goal is keeping fake and throwaway accounts out, you want the decision, not five raw lookups to stitch together. One call returns the verdict and why.
Frequently asked questions
Can I still call the checks separately?
