Global OTP routing paths optimized for cost and latency

AI OTP infrastructure

Every one-time password, routed for cost and speed.

L-Chain sits in front of your carriers and decides — per message — which route delivers within your latency budget at the lowest possible price.

Three steps between your login screen and a cheaper delivery.

STEP 1

Connect

Point your existing send call at the L-Chain endpoint. Keep your carrier accounts — we route across them.

STEP 2

Constrain

Set latency ceilings and cost targets per market. No model tuning, no data science team.

STEP 3

Optimize

The routing model learns from every delivery receipt and rebalances traffic continuously.

POST /v1/otp/send
{
  "to": "+226 70 00 00 00",
  "template": "login_code",
  "constraints": {
    "max_latency_ms": 3000,
    "optimize": "cost"
  }
}

A routing model built for OTP economics.

01

Price-aware routing

Every request is scored against live carrier rates. L-Chain picks the cheapest route that still clears your latency budget — per country, per operator, per minute.

02

Latency budgets you set

Declare a target like “under 3s in Burkina Faso”. The model treats it as a hard constraint and only optimizes cost inside it.

03

Predictive failover

When a carrier starts degrading, L-Chain sees it in the delivery curve and reroutes before your users ever hit a retry.

04

Spend forecasting

Projected monthly OTP cost by market, with the savings each routing decision produced against your previous provider mix.

Live AI demo

Try the routing engine right here.

Set a market, a latency ceiling and a monthly volume. The model picks the cheapest compliant route instantly — no sign-up, no demo request, and the session is discarded when you close the tab.
