OTP Authentication

Global OTP Delivery. Under 2 Seconds.

Eliminate user drop-offs during mission-critical registration and checkout flows. Our multi-channel OTP API utilizes intelligent low-latency routing algorithms that automatically evaluate network congestion in real-time. By dynamically falling back between Tier-1 SMS aggregators, WhatsApp Business API, and SIP Voice channels, we guarantee synchronous 2FA payload delivery across 190+ countries in under 2 seconds.

Smart Routing & Fallbacks

Never lose a customer to a telecom outage again. If the primary SMS route experiences delivery latency exceeding 3 seconds, our state machine automatically cascades to an alternate Tier-1 aggregator. If SMS fails entirely at the carrier level, we instantly trigger a WhatsApp OTP or localized Text-To-Speech (TTS) Voice call to ensure the verification payload reaches the handset.

Latency-based dynamic route weighting

Fraud Prevention API

Protect your platform from automated bot farms, toll-fraud injection, and SMS pumping attacks. Our API edge includes built-in Token Bucket rate limiting, IP reputation checking, geo-fencing, and temporal velocity checks to automatically drop suspicious verification requests before they incur network costs.

Single API Endpoint. Zero Infrastructure.

You do not need to generate, hash, or store the codes. Simply make a POST request with the phone number. We generate a cryptographically secure 6-digit pin, deliver it, and expose a `/verify` endpoint for you to validate the user's input.

// 1. Request OTP

fetch('/v1/otp/send', {
  method: 'POST',
  body: JSON.stringify({
    phone: '+919876543210',
    channel: 'sms',
    length: 6,
    expiry: 300 // seconds
  })
});

// 2. Verify Input

fetch('/v1/otp/verify', {
  method: 'POST',
  body: JSON.stringify({
    reference_id: 'req_9982x',
    code: '492815'
  })
});

// Response: { status: "approved" }
