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.
