Before proceeding with Postman integration, be sure to register at app.newscatcherapi.com and get an API Key.
I added the Fork into my own Workspace. So, once it is done, you should see:
Added collection on the left side with 3 endpoints
Authorization window where you will have to put your API key
Documentation page on the right
Feel free to explore our News API by checking the Documentation page on each endpoint and use different combinations of filters and parameters to get the most relevant results.
