How to Access an API

[snippsat]

You most give more info about the API.

Where do I place the DLL in my project folder and how do I code in my program to and use this API?

This is strange question that is usally not askes at all when try to acess a API.
To show a normal way to access access a API,eg can use OpenWeather.
So use Requests and then use the Json respone that API give back.

import requests

api_key = 'xxxxxxxxxxxxxxxx'
city = 'london'
celsius = 'metric'
url = f'http://api.openweathermap.org/data/2.5/weather?q={city}&units={celsius}&APPID={api_key}'
response = requests.get(url).json()

print(response.get('name'))
print(response['main'].get('temp'))

Output:
London
11.34
