How It Works

From API Call to Delivered OTP in Seconds

Three steps. No infrastructure to manage. No SIM cards to buy.

Step 01

Your app calls our API

A single POST request with the recipient's number and channel. JSON in, OTP out — from any language.

POST /api/v1/otp/send
{
"recipient": "+91987...",
"channel": "sms"
}

→

Step 02

We route to the nearest node

Our engine selects the best volunteer node — country-matched, lowest load, highest uptime score, daily cap respected.

→ Node #7841 selected
Country: IN · Score: 98.7
Latency: < 200ms

→

Step 03

Node sends SMS from a real phone

The volunteer's Android app sends the OTP via the native SMS stack — a real carrier, a real number, delivered.
