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.

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
Ajay Bulusu is a co-founder of NextBillion.ai, bringing deep expertise in geospatial technology and large-scale location platform engineering. His journey began in 2017 as part of Grab's pioneering Geo team, where he helped build the location infrastructure underpinning one of Southeast Asia's largest mobility and logistics platforms. That experience revealed how critical — and how underserved — accurate, flexible location technology was for real-world operations. Driven by a mission to democratize sophisticated location intelligence, Ajay co-launched NextBillion.ai in 2020. Under his technical leadership, the platform has scaled to serve 150+ businesses globally, optimize over 10.9 million deliveries and field tasks, and deliver more than $11 million in documented cost savings to customers.
Co-Founder
Gaurav Bubna drives product innovation at NextBillion.ai, bringing a proven track record of building successful products from scratch across ride-hailing, food delivery, and logistics. Before co-founding NextBillion.ai, Gaurav held product leadership roles at Grab, Ola, and Morgan Stanley — organizations where location technology and operational efficiency are existential. His time on Grab's Geo team alongside Ajay and Shaolin crystallized the vision: logistics and field service businesses needed enterprise-grade location intelligence without prohibitive per-call pricing. Since launching NextBillion.ai in 2020, Gaurav has led the product evolution that has helped the platform navigate over 557 million miles and raise $34.25M in venture capital from investors including Lightspeed and Microsoft's M12.
Co-Founder
Shaolin Zheng is a co-founder of NextBillion.ai, contributing deep technical expertise in geospatial systems and scalable mapping infrastructure. Like his co-founders, Shaolin's formative experience building location technology for Grab's Geo team gave him firsthand insight into the operational gaps that generic mapping solutions leave unaddressed — particularly for field service and logistics businesses operating at scale. His engineering perspective shapes NextBillion.ai's core philosophy: location technology must be customizable, cost-predictable, and production-reliable. The platform he helped build now powers GPS tracking, route optimization, and field service intelligence for over 150 businesses worldwide, with on-premise deployment options and SOC 2 Type II and ISO/IEC 27001:2013 certifications ensuring enterprise-grade security.
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.
