Is this possible ?

Question

If I had an API in form of a URL can I use it alone to get all the other websites using/calling that API/URL ?
I'm making a research and I'm trying to find more efficient ways to do it. That's the reason for the question.

Answer 1

This is a very common thing, in fact you can see something like this even if you use Google to search for flights or currency exchange rates or stock prices. Google itself does not need to store that kind of information in real time, but if there is a query, it can collect the data instantly from other websites or APIs and display it for you.

Answer 2

Your question is a big confusing. Technically there's no issues getting data through an API and displaying it in your site, this is actually a common occurrence

You would need to look for any limitations in your API tho (such as number of requests, auth, if all the content you're looking for it's available, etc)
