App for website without api?

Question

API

In general, for example, there is a site on the Internet for which I want to write an ordinary web application (not mobile). and I have no idea where to get its api documentation and whether it exists at all ... is it possible in this case to limit ourselves to sniffers like fiddlera for example?

Answer 1

, there the network tab
is written the whole history of requests and responses
