When every second counts, your routing engine cannot afford to fail. NextBillion.ai's Route Optimization API is purpose-built for emergency response operations — delivering sub-second dispatch-ready routes, real-time dynamic rerouting, and 50+ constraint support so your teams reach critical locations faster, smarter, and without on-road surprises.
A complete API suite engineered for time-critical emergency response dispatch, routing, and fleet coordination at scale.
Generate dispatch-ready, multi-stop emergency response routes in seconds with 50+ hard and soft constraints — including vehicle type, shift windows, priority stops, and regulatory compliance — ensuring the fastest, safest path every time.
Instantly match emergency units to incidents using dynamic parameters including proximity, availability, shift timing, and location familiarity — enabling smart 1:1 dispatch and real-time reassignment when situations evolve.
Maintain sub-meter real-time visibility over every emergency vehicle and field unit, with configurable alerts for route deviation, idle time, and boundary events — keeping dispatchers informed and in control throughout every response.
Define dynamic operational zones, incident perimeters, and restricted areas that automatically trigger real-time alerts and route adjustments — ensuring vehicles never enter unsafe or compliance-sensitive boundaries during active responses.
Deliver precise, vehicle-specific turn-by-turn navigation to emergency response drivers with real-time and historical traffic intelligence, custom road attribute overrides, and departure-time routing for scheduled and on-demand missions.
Automate the handoff from optimized route planning to on-road execution — pushing updated dispatch instructions to driver apps and fleet systems in real time, eliminating manual delays and errors during time-critical incident response.
Emergency response operations cannot tolerate routing engines built for parcel delivery. NextBillion.ai's Route Optimization API is engineered for the highest-stakes dispatch environments — processing priority incident assignments, vehicle-specific road constraints, and real-time rerouting around closures or restricted zones in under a second. With 50+ configurable constraints, custom road attribute overrides via the Road Editor App, and predictable per-vehicle pricing that scales with your fleet rather than your call volume, your operation gets enterprise-grade routing intelligence without the cost unpredictability of legacy mapping APIs.

Ajay Bulusu is a Co-Founder of NextBillion.ai and a driving force behind the company's vision to make sophisticated location intelligence accessible to businesses worldwide. Ajay's journey began at Grab's Geo team in 2017, where he and his co-founders witnessed firsthand the transformative power of precision routing technology — and the costly limitations of existing solutions that were too rigid, too expensive, and too generic for real-world operational demands. That experience inspired the founding of NextBillion.ai in 2020. Today, Ajay leads efforts to build the routing infrastructure that powers emergency response, logistics, and mobility platforms globally — with a focus on reliability, speed, and enterprise scalability.
