An SMS API you'd actually want to use.

Send SMS and OTPs from your app, website, or internal system. Bearer tokens — never passwords in query strings. Signed webhooks, idempotency keys, a real sandbox, and predictable status codes.

Two endpoints — send and verify. We handle 6-digit codes, single-use enforcement, 5–10 minute expiry, attempt limits, resend cooldowns, and fraud monitoring. You handle nothing.

✓ 6-digit, single-use codes with configurable expiry
✓ Attempt limits, resend cooldowns, IP throttling
✓ Fraud signals on unusual volume or geography
