I'm learning Python and trying to understand this example using the requests library:
```python
import requests
response = requests.get("https://randomfox.ca/floof")
print(response.status_code)
print(response.text)
```
The status code makes sense to me, but the response text only contains information about a fox image and a link. Why doesn't it also include things from the main website, such as its logo, page text, or other content?
Is this because the API endpoint was specifically designed to return only that data? If a website owner wanted to, could an API return much more information, or even information that doesn't accurately represent the website?

The browser isn’t receiving hidden information and choosing to display only the fox details. It is receiving the exact response provided by that URL. If you visit the main site, the server sends a webpage containing HTML and possibly references to CSS, JavaScript, and images. The API endpoint sends only the JSON data its creator decided to expose. The server could return more fields if its developer implemented it that way, but clients can only access information the server actually sends.
A GET request simply asks a server for the resource at a particular URL. The server can return whatever representation it has configured for that endpoint: JSON, HTML, an image, plain text, or something else. In this case, `response.status_code` contains the HTTP result, such as `200` for success, while `response.text` contains the returned data as text. Since the endpoint returns JSON, you could also try `response.json()` to turn it into a Python dictionary.
The important distinction is that an API endpoint is usually designed for programs, while the main page is designed for people using a browser.
Exactly—the endpoint determines what you receive. Someone programmed `https://randomfox.ca/floof` to return a small JSON response containing a fox image URL and a page URL. The main website is a different resource, so it can return HTML with logos, text, and page layout instead. Each URL can be programmed to provide a different response.
That clears it up. I was mainly trying to understand the logic behind why the responses differ.
So the endpoint’s response is intentionally limited, rather than being a complete copy of the website with some parts removed.
