The Ultimate Guide to Routing APIs

The Ultimate Guide to Routing APIs

Published: August 22, 2025

In today’s hyper-connected world, Routing APIs are powering everything from ridesharing apps to international supply chain operations. These APIs handle route calculation, travel time prediction, traffic avoidance, and waypoint optimization that are all essential for modern mobility solutions. Choosing the right routing API is critical for any application that needs to calculate directions, optimize journeys, or manage logistics.

Developers have multiple choices including the Google Routes API, HERE Routing API, and MapQuest API. In this guide, we’ll explore what each API offers, their strengths and limitations, real-world usage examples, pricing considerations, and code examples to help you decide which API fits your needs.

What is a Routing API?

A Routing API is a cloud-based service that calculates the best route between two or more points. It’s not just about finding the shortest distance; it’s about finding the most efficient, context-aware path using real-time traffic data, historical patterns, and constraints.

Core capabilities of a Routing API:

  • Route Calculation: Calculates ideal routes between two or more locations. Generates turn-by-turn directions. 

  • Multiple Transport Modes: Drive, walk, cycle, public transit, trucks, and EVs.

  • Traffic Awareness: Incorporates live and predicted traffic conditions.

  • Multi-Stop Optimization: Reorders waypoints to reduce travel time.

  • Advanced controls: eco-friendly route calculation, toll fee estimates, traffic-aware polylines, and stopover qualifiers.

  • Geospatial Data Integration: Works with geocoding to turn addresses into coordinates.

  • Search Along Route: find places of interest (restaurants, gas stations) along a journey.

Google Routes API

The Google Routes API is part of the Google Maps Platform and is ideal for developers building applications that need reliable and precise routing capabilities.

Key Features:

  • Compute Routes: Calculates optimal routes between two or multiple waypoints, returning ETAs, turn-by-turn directions, and distances. Real-time traffic conditions are factored into the calculations.

  • Compute Route Matrix: Provides distances and travel times between multiple origins and destinations, useful for fleet dispatch and delivery management.

  • Search Along Route: Finds points of interest (restaurants, gas stations, etc.) along a planned route.

  • Advanced Controls: Specify routing preferences (avoid tolls, eco-friendly routes, pass-through waypoints vs. stops) and enable performance optimizations such as gRPC for lower latency.

  • Modes Supported: Car, walking, transit, cycling, and two-wheeler motorized vehicles.

  • Real-Time Traffic, Tolls, Eco Routing: Includes data about current traffic, toll costs, and optionally eco-friendly alternatives for eligible regions.

A Brief Feature Comparison

The Google Routes API, HERE Routing API, and MapQuest API each offer distinct features catering to various routing and mapping application needs. Google Routes API provides comprehensive traffic data, supports multiple travel modes including driving, walking, biking, transit, and two-wheel motorized vehicles, and offers advanced functionalities such as eco-friendly route suggestions, toll fee information, route optimization, and the ability to search for points of interest along a route. It stands out in traffic awareness, turn-by-turn directions, accurate ETAs, and matrix-based routing for large-scale logistics, but has limitations in heavy truck routing features and offers a restricted free tier.

HERE Routing API is known for its power and flexibility in multi-waypoint routes, especially for vehicles needing truck-specific guidance regarding weights, dimensions, and hazardous cargo. It incorporates rich options for real-time traffic, road closures, truck routing, and environmental policies, making it highly suitable for freight, logistics, and smart mobility solutions. HERE also integrates public transit data and provides route optimization tools, although its customization options may be less flexible than some highly industry-focused alternatives.

MapQuest API, meanwhile, shines with features like draggable routes, a generous free tier, support for planning up to 26 stops, saving and customizing entire journeys, simple interface, and automatic calculations for trip costs and IRS reimbursements. MapQuest is ideal for basic routing, travel planning, and educational mapping projects, but its functionality such as toll and advanced truck routing data or eco-routing are more limited compared to Google and HERE.

In summary, Google Routes API excels in advanced traffic-aware mapping and eco-friendly routing, HERE Routing API leads in trucking and logistics-specific capabilities, and MapQuest API offers user-friendly simplicity and broad access for basic route planning tasks. The choice between them should be based on the complexity of routing needs, integration flexibility, price considerations, and the scale at which you plan to deploy your application.
