## Implementation

**Objective**: Create an app with 4 endpoints, which returns different information and insights of Github profiles. 3 endpoints include:

1. Input: location and programming language&#x20;

   Output: Return 30 Github profile URLs&#x20;
2. Input: Github profile URL

   Output: Profile personal information summary (with different attributes)
3. Input: Github profile URL

   Output: All repository summary connected to the profile

The object to create 3 endpoints is to understand, how to structure and separate multiple requests.

```
url = "https://api.github.com/search/users?q=location:{0}+language:{1}".format(first, second)
response_dict = requests.get(url).json()
```
