Using Public API provides access to hundreds of datasets across various topics such as business, environment, and transportation. To access the data, they offer a Public API that developers can use to create applications, websites, and more.

Getting Started

Before you can start using the API, you need to obtain an API key. You can do this by following these steps:

  1. Go to and sign in or create an account.
  2. Under the “Developer Settings” tab, click “Create New App”.
  3. Give your app a name and description.
  4. Click “Register App” and your API key will be displayed.

Making API Requests

Once you have your API key, you can start making requests. Here is an example of how to get data from the “Active Marijuana Licenses in Colorado” dataset using JavaScript:

const apiKey = 'YOUR_API_KEY';
const datasetId = '45a87e14-4a9e-4c83-a04a-4c6c3e67a3b7';
const query = '$select=name';

const url = `${datasetId}.json?${query}&$$app_token=${apiKey}`;

    .then((response) => response.json())
    .then((data) => console.log(data))
    .catch((error) => console.error(error));

This will retrieve the names of all active marijuana licenses in Colorado and log them to the console.

API Documentation

The website provides detailed documentation on all available datasets and how to use them with the API. You can find the documentation here:

In addition, the website offers a Query Builder tool that allows you to experiment with different queries and see the results in real-time:


The Public API is a powerful tool for accessing valuable data on a wide range of topics. With a bit of JavaScript know-how and the documentation provided, you can create your own custom applications and gain insights from the data.
