Working with CHAPS IDOS Internet API

CHAPS IDOS Internet API is a public API that provides access to the public transport schedules, routes and other related data across the Czech Republic. In this guide, we will explain how to work with CHAPS IDOS Internet API, including how to authenticate, retrieve data, and how to use the API in your JavaScript applications.

Getting Started

Before you can use CHAPS IDOS Internet API, you need to register on the website and obtain an API key. Once you have done that, you can use the API to retrieve data from the CHAPS servers.

Authentication

To authenticate your requests to the API, you need to include your API key in the HTTP headers. You can do this in JavaScript by using the fetch library to make HTTP requests and including the API key in the headers:

fetch('https://api.chaps.cz/v2/...', {
  headers: {
    'Authorization': 'Bearer <your-api-key>',
    'Content-Type': 'application/json'
  }
})
  .then(response => response.json())
  .then(data => console.log(data))
  .catch(error => console.error(error));

Retrieving Data

CHAPS IDOS Internet API provides a range of endpoints that allow you to retrieve data about transport schedules, routes and stops. For example, to retrieve the details of a stop, you can use the following code:

fetch('https://api.chaps.cz/v2/stop/...', {
  headers: {
    'Authorization': 'Bearer <your-api-key>',
    'Content-Type': 'application/json'
  }
})
  .then(response => response.json())
  .then(data => console.log(data))
  .catch(error => console.error(error));

Similarly, to retrieve the schedule of a particular route, you can use the following code:

fetch('https://api.chaps.cz/v2/schedule/...', {
  headers: {
    'Authorization': 'Bearer <your-api-key>',
    'Content-Type': 'application/json'
  }
})
  .then(response => response.json())
  .then(data => console.log(data))
  .catch(error => console.error(error));

Conclusion

In this guide, we have explained how to work with CHAPS IDOS Internet API, including how to authenticate, retrieve data and use the API in your JavaScript applications. By following the steps outlined in this guide, you should be able to build powerful applications that leverage the public transport data provided by CHAPS.
