What is Shernova?
Shernova verifies phone numbers through missed-call matching instead of SMS OTP. Users place a short call to a gateway number; Shernova confirms the caller and completes verification without sending text messages.
Why Shernova?
- Lower cost than SMS OTP in many markets
- Fast user experience — one short call instead of waiting for a code
- REST API and Flutter SDK — headless core with optional ready-made UI
- Organization-scoped billing with hold/capture credits and a full ledger
- Signed webhooks when verification completes
