I like the idea but I was skeptical as to how well it works and noticed the video on the main page of your website which scans coinmarketcap seems to be wrong. It gets 200 cryptocurrency names but only 100 prices which means only the first result is correct.

I have a similar idea that I'm working on, your site is definitely bookmarked and will try the extension later.

Good catch, uberswe. Was an older video and I flubbed the selection process - here it is working correctly: https://www.kapwing.com/videos/5dbc3e33ee4d0f00136d01e6

Nice, that looks much better!

Hi, is it the chrome extension that does whole work or There is a separate background task on your side that actually runs those recipes ?

Hi, it's both. There's 'local' scraping where the results of what you selected is ready to download as soon as you click results - no signup or server needed.

And then anything's that saved as a recipe runs in the cloud.

Also interesting that this main example is also a violation of coinmarketcap's terms. They have a paid API.

If i use my pen and notebook to write down all those values, am i also in violation of those terms?

If they don't want their data to be scraped, it is up to them to secure it.

The argument you're making here is 'I don't believe in copyright'. Which is fine, but doesn't really negate my point.

It's a moot point. I very much believe in copyright, but you can't just put info in the public domain and yell, "Take a look but don't remember/retain it" in the name of copyright. If I redistribute it or reuse it for commercial purposes without your consent then maybe there is a case. But if I am just scraping it, i.e remembering it... Come on now.

Otherwise everyone who gets the lyrics to copyrighted songs or memorizes them and sing them in the shower is also in violation of copyright. Which would reduce the whole copyright thing to ridiculousness.

All I said that it's against their term of use. I didn't try to make a point about whether it should be or not. If you are curious about it, and whether using pen and paper is allowed, take a look at it.

I think so too. From their terms [1]

Then use data from a free API without any TOS, and more data like separating bid and ask:
