OTP without the boilerplate
Start a verification challenge with one POST, check it with another. Throttling, expiry, attempt limits, and channel fallback are built in. The bits every team rewrites the first time.
What you get
Six things you don't have to build.
Everything below is on by default the moment you mint your first API key. No premium tier, no add-on.
- 1 One API for SMS, WhatsApp, and email codes
- 2 Configurable length, format, expiry, attempts
- 3 Per-recipient throttling out of the box
- 4 Fallback to another channel if delivery silently fails
- 5 Localised templates with sensible defaults
- 6 Per-challenge audit log for compliance reviews
Other channels
One API. Three more channels.
