How can I fetch data on demand using an API?

You can fetch data on demand by making HTTP requests to an API endpoint whenever you need the data.

What programming languages can I use to make these API calls?

You can use various programming languages like JavaScript, Python, Java, or even tools like Postman to make API calls.

Can you show me an example in Python?

Sure! You can use the 'requests' library in Python. Here's a simple example:

import requests
response = requests.get('https://api.example.com/data')
print(response.json())

What if the API requires authentication?

In that case, you would typically include an API key or token in the headers of your request. Here's how you can do it:

headers = {'Authorization': 'Bearer YOUR_API_KEY'}
response = requests.get('https://api.example.com/data', headers=headers)
