Introduction

Are you looking for a public API to work with? Check out the RTD Denver API! This API provides access to public transportation data in the Denver, Colorado area. In this blog post, we will provide an overview of the API and provide some example code in JavaScript.

API Overview

The RTD Denver API provides access to static and real-time data for their public transportation services. This data includes information on routes, stops, schedules, and more. The API uses the GTFS (General Transit Feed Specification) format for its data.

To use the API, you will need an API key which you can get by creating an account on the RTD Denver developer website.

Example Code

Let's take a look at some example code using the RTD Denver API.

Retrieving Routes

To retrieve a list of all available routes, you can make a GET request to the following URL:

https://www.rtd-denver.com/api/routes

Here is an example JavaScript code using the fetch function to get all routes:

fetch('https://www.rtd-denver.com/api/routes?key=<YOUR_API_KEY>')
  .then(response => response.json())
  .then(data => console.log(data));

Replace <YOUR_API_KEY> with your actual API key.

Retrieving Bus Stops

To retrieve a list of all bus stops for a route, you can make a GET request to the following URL:

https://www.rtd-denver.com/api/stops-for-route/<ROUTE_ID>?key=<YOUR_API_KEY>

Here is an example JavaScript code using the fetch function to get all bus stops for route 1:

fetch('https://www.rtd-denver.com/api/stops-for-route/1?key=<YOUR_API_KEY>')
  .then(response => response.json())
  .then(data => console.log(data));

Retrieving Real-Time Bus Data

To retrieve real-time data for a bus stop, you can make a GET request to the following URL:

https://www.rtd-denver.com/api/realtime/stop/<STOP_ID>?key=<YOUR_API_KEY>

Here is an example JavaScript code using the fetch function to get real-time data for stop STP_3317:

fetch('https://www.rtd-denver.com/api/realtime/stop/STP_3317?key=<YOUR_API_KEY>')
  .then(response => response.json())
  .then(data => console.log(data));

Conclusion

The RTD Denver API provides a wealth of public transportation data for the Denver, Colorado area. By using the GTFS format, it makes it easy to work with the data. We hope these examples in JavaScript have been helpful and inspire you to try using the RTD Denver API in your next project!
