Distance Matrix API
Compute real-time and historical travel times, distances, and ETAs between up to 5,000 origins and 5,000 destinations in a single API call — eliminating batch splitting and calculation inconsistencies at scale.
Calculate precise distances, travel times, and reachable radius zones between any zip codes or geographic coordinates using NextBillion.ai's Location Calculator API. Built for logistics platforms, field service operations, and delivery networks that need reliable, scalable proximity intelligence — without per-call pricing penalties or the 25×25 matrix ceiling holding them back.

From zip code radius queries to massive distance matrices, our APIs deliver the spatial intelligence your platform depends on.
Compute real-time and historical travel times, distances, and ETAs between up to 5,000 origins and 5,000 destinations in a single API call — eliminating batch splitting and calculation inconsistencies at scale.
Generate road-network-accurate travel-time and travel-distance radius polygons from any zip code or coordinate, showing the true reachable area for any vehicle type under real traffic conditions.
Compute precise, compliant, single-vehicle routes between any two zip codes or coordinates, with support for truck-specific constraints, toll avoidance, and multiple intermediate waypoints.
Automatically group zip codes and delivery stops into proximity-based clusters for territory design, zone balancing, and pre-routing segmentation before full route optimization runs.
Define virtual radius boundaries around zip codes or custom polygons, trigger automated events when assets enter or exit zones, and enforce territory-based dispatch rules in real time.
Transform zip code stop lists into dispatch-ready multi-stop routes in seconds, solving complex logistics problems with 50+ hard and soft constraints and predictable per-vehicle pricing.
NextBillion.ai's Location Calculator APIs go far beyond simple straight-line distance lookups. Whether you need to find all zip codes within a 50-mile radius, calculate true road-network travel times between thousands of origin-destination pairs, or define reachable service zones for field technicians — our platform delivers road-accurate results at the scale your operation demands. Unlike per-call pricing models that punish high-frequency queries and re-optimization cycles, NextBillion.ai's per-vehicle and per-order pricing keeps costs predictable as your query volumes and fleet size grow.

See how logistics platforms and field service operators use our Location Calculator APIs to cut costs and scale smarter.
Built by geo-technology veterans, our Location Calculator APIs are engineered for the scale, accuracy, and cost control that enterprise logistics platforms require.
Process distance matrices up to 5,000×5,000 in a single call — no 25×25 caps or costly batch splitting required.
Per-vehicle and per-order pricing models prevent budget overruns as query volumes and re-optimization frequency increase.
All radius and distance calculations run against real road networks with live traffic — not inaccurate straight-line approximations.
24×7 hands-on support from solutions engineers ensures fast integration and reliable production performance from day one.
Geo-technology veterans building the location intelligence platform logistics deserves.

Co-Founder
Gaurav drives product innovation at NextBillion.ai, bringing deep expertise in building location-technology products from the ground up. His background spans ride-hailing, food delivery, and logistics at companies including Grab, Ola, and Morgan Stanley — environments where distance computation accuracy, ETA reliability, and API scalability directly determine operational outcomes and customer satisfaction. At NextBillion.ai, Gaurav channels that experience into building routing and location intelligence tools — including the Distance Matrix and Isochrone APIs — that give logistics and field service platforms the spatial computing power they need, priced for how real operations actually scale. His vision is straightforward: sophisticated geo-intelligence should be accessible to any business that needs it, not just those with nine-figure engineering budgets.

Co-Founder
Ajay Bulusu co-founded NextBillion.ai after years of working on geo-infrastructure at Grab, where he witnessed firsthand the gap between what existing mapping and location APIs could deliver and what high-throughput logistics platforms actually needed. That gap — expensive per-call pricing, rigid matrix size limits, generic routing that ignored real operational constraints — became the founding problem NextBillion.ai was built to solve. Ajay leads with a product and engineering philosophy rooted in operational reality: location APIs must perform at the scale, speed, and cost structure of the businesses they serve. Under his leadership, NextBillion.ai has delivered over $11 million in cost savings to customers and optimized more than 10.9 million deliveries globally.

Co-Founder
Shaolin Zheng is a co-founder of NextBillion.ai and a core member of the engineering and geo-technology leadership team that built the platform from its earliest foundations. Like his co-founders, Shaolin's path to NextBillion.ai ran through Grab's geo team, where he developed deep expertise in the spatial computing challenges that underpin real-world logistics and mobility operations. His technical contributions span the platform's core location intelligence infrastructure — from the distance matrix computation engine to the routing algorithms that power the Isochrone and Directions APIs. Shaolin's focus is on building location technology that is not only accurate and scalable but genuinely customizable for the diverse operational needs of the 150+ businesses NextBillion.ai serves globally.
A Zip Code Distance API calculates the distance and travel time between two or more zip codes by routing the query through a real road network rather than drawing a straight line. NextBillion.ai's API geocodes the zip code centroids, runs a road-network-aware calculation factoring in speed limits and live traffic, and returns precise mileage and ETA data in milliseconds.
