Frequently Asked Questions

How do you determine if a domain is malicious?

We use a combination of Real-time Blacklists (hot cache), Machine Learning models (entropy, n-grams), and Heuristics (pattern matching) to score every request in under 50ms.

Do you offer a free trial?

We do not offer a public free tier. However, students, researchers, and partners can request a complimentary 1-month Startup key by emailing inbox@cyberapi.io with their use case. Approvals are at our discretion.

Can I use this for frontend validation?

Absolutely! Our API supports CORS so you can call it directly from your client-side forms to provide instant feedback to users.
