Someone else's API in your project, is it possible?

Question

API

Hey! Can I use someone else's API in the production version of the project, namely, pull data from various resources, assemble them and give them in my wrapper (for example, films, music, books) ... when placing an order, it will naturally be transferred to the owner's resource with all the parameters at once for purchase

Answer 1

The "foreign API" probably has terms of use, so read it.

Answer 2

If the api is public, then there should be a description of what and why it can be used
. N-r quote
XXXXX provides its users with a unique service - the ability to use an excerpt from any book for introductory reading.
The name of one site with the letter L

Answer 3

I understand that you want to write a parser. Since this data is in the public domain (isn't it?), then you could very well just go to this site, copy what you need, and paste it on your site. You just automate this process.
Otherwise, if you are interested in the question from a legal point of view - what will you get for it, then here's what: if it's a parser, then it's better to talk to the owner of the site. If the site has a public API, then use it, and you won’t get anything for it, the owner of the site allowed you to do this.
