API Requests: GET and POST

Comparison of POST and GET requests: POST sends a JSON body with currency data to an API and receives a response; GET sends a URL like wttr.in/London?format=j1 and receives weather data back

Anatomy of an API URL

Terminal output from wttr.in showing a weather report for Ipswich with current conditions (partly cloudy, 8 degrees Celsius) and a forecast table for morning, noon, evening, and night

GET request → https://wttr.in/London?format=j1
