Table of Contents

In everyday life, Google Maps is simply a navigation tool that helps us get from point A to point B. But from a professional point of view, it represents something much more powerful – it's a huge database filled with valuable business data just waiting to be leveraged. To make the most of this treasure trove of information, you can make use of the Google Maps API for developers.

Understanding APIs: The Foundation

But what exactly is an API? An API stands for Application Programming Interface. It is an interface that enables you to use the functionalities of a third-party system without having to worry about its internal workings. Think about it this way: driving applications provide access to a map and GPS tracking – a map that shares a lot of similarities with Google Maps. Rather than reinventing the wheel, these applications prefer to use the Google Maps API to directly integrate its functionalities into their own systems.

Of course, the Google Maps API is much more than a simple map. It can be used in a wide variety of ways, and the possibilities are truly extensive.

Exploring the Full Range of Google Maps APIs

To find out about all the use cases available to you, you need to go to console.cloud.google.com. From there, click on the navigation menu, select "APIs & Services," and then "Library." Scroll down a little bit and click on the "Maps" tab, and here you'll find the full list of available APIs.

Interactive Maps APIs

Maps JavaScript API: With these APIs, interactive maps can be displayed and manipulated on your website. You can integrate a customized map directly into your web page, choosing everything from the zoom level to the information displayed, the colors, and even the theme. Some developers even have fun creating maps related to the Mario world – showing just how customizable these tools can be.

Maps Embed API: You can embed a Google Maps map using an iframe tag on your website, all without JavaScript. This approach is often found on online directories where a business name is associated with a specific point on the map.

Maps SDK for Android: Create interactive maps specifically for your Android applications.

Maps SDK for iOS: The same functionality, but designed for iOS applications.

Maps Static API: With a simple HTTP request, you can embed a Google Maps image on a website. We're talking about a static image here, not an interactive map.

Specialized Geographic APIs

Maps Elevation API: This API handles topography. Based on coordinates, you can find out the elevation of a location. This value can be positive or negative, depending on whether you're above or below sea level.

Roads API: This API allows you to trace a route taken by a user, providing detailed information about the path traveled.

Directions API: This one is quite self-explanatory. You can obtain directions between two locations. These locations can be expressed in text form or as geographic coordinates. Just like normal Google Maps usage, the route can be calculated for travel by car, bike, on foot, or via public transport.

Geocoding API: This powerful tool transforms addresses into coordinates with latitude and longitude. It also works in reverse – transforming coordinates back into readable addresses. If you're interested in extracting coordinate data, you might find our guide on how to scrape Google Maps coordinates particularly useful.

Geolocation API: This provides a solution for geolocating a device via a relay antenna or a WiFi access point. At the same time, you get a radius showing how accurate the result is.

Street View and Utility APIs

Street View Publish API: Street View needs no introduction – that's what makes those immersive 360-degree images possible.

Street View Static API: Similar to the Maps Static API, you can integrate a Street View image into a web page.

Time Zone API: Based on coordinates, the Time Zone API returns UTC (Universal Coordinated Time), which harmonizes dates around the globe.

We could go on and on, but there's another major feature of the Google Maps API that deserves special attention.

The Business Data Goldmine: Places API

With the Google Maps API, you can search for businesses on the platform. This is accomplished through the Places API, which provides data on over 200 million businesses worldwide. You can filter this data according to your own criteria: business type, rating, location, wheelchair accessibility, and much more.

The Google Maps API can also be used to calculate routes and distances. As we mentioned, Google Maps is essentially a GPS system. We've already talked about the Directions API for creating itineraries, but you can have even more specific functionality thanks to the Distance Matrix API. Here, you can calculate both the distance and travel time between a starting point and an ending point.

Of course, you don't have to use just the Google Maps APIs in isolation. These APIs can be integrated with other Google tools to create comprehensive solutions.

Getting Started: How to Get Google Maps API Key

Now we can address the practical question: How do I get started with the Google Maps API?

Before you can use the Google Maps API, you need to obtain an API key. The process is similar to what we've outlined before, meaning you need to go to console.cloud.google.com. For a more detailed walkthrough, check out our comprehensive Google Maps API key guide that walks you through every step.

Step-by-Step Google Maps API Key Setup Process

The first thing you're going to do is create a new project. Here's the process:

  1. Create a New Project: Select "Create a new project," add a name to your project, and create it.
  2. Select Your Project: Once your project has been created, select it from your dashboard.
  3. Enable APIs: Now you have to identify the specific API you want to use. For example, if you're interested in business data, you'd want something like the Places API.

Here's where things get important: The problem with the Google Maps API is that if you enable your API, you also have to create a billing account. The Google Maps API is a paid service, so you'll need to set up billing before you can use most of the powerful features.

For demonstration purposes, let me show you the process with a free API like Google Sheets instead:

  1. Select your API
  2. Enable it with just a click
  3. Navigate to "IAM & Admin" and then "Service Accounts"
  4. Create a service account
  5. Fill in the service account ID
  6. Create and continue

Once this is done, an email address is created for your service account. Click on it, and you'll be able to create your authentication key. Click on the "Keys" tab, add a key, create a new key, and choose JSON file format.

The resulting file contains various authentication details, including your private key ID. Once you have this setup complete, you can integrate the API into your projects.

Now, I have to admit – not being a developer myself, I don't find this process particularly easy. But fortunately, you can benefit from the extensive code examples provided by Google to help with implementation.

The Reality Check: Google Maps API Pricing and Limitations

Finally, bear in mind that using the Google Maps API comes at a cost. You can take a look at the detailed price list at maps.platform.google.com/pricing.

As we've seen, Google Maps offers plenty of different APIs, and maybe you're particularly interested in commercial use – namely the Places API. This is the API that enables you to gather business information based on category and location.

The Limitations That Matter

Nevertheless, this API suffers from several significant limitations:

1. Result Limitations: To begin with, you can only retrieve 120 results per query. If you're trying to get comprehensive data for a large city or specific business category, you'll hit this wall quickly.

2. Data Restrictions: Secondly, while you can get phone numbers through the API, you cannot get email addresses – a crucial piece of contact information for business outreach. If you need to extract email addresses from businesses, our guide on how to find email addresses from Google Maps offers practical alternatives.

3. High Costs: Finally, Google Maps API pricing varies from $32 to $40 per 1,000 results, which can add up quickly for large-scale data collection projects.

The Game-Changing Alternative: Scrap.io

To fill this gap, we have created Scrap.io. Scrap.io is a tool specifically designed to extract data from Google Maps within just a few clicks. By creating your account via the link in the description, you also benefit from our API access.

Why Scrap.io Changes Everything

The major difference between Scrap.io and the Places API is that you can get significantly more data. Not only do you have access to Google Maps data, but you also have access to data displayed on the associated websites. This includes metadata, social networks, and – crucially – email addresses.
