Hi @OlenaY,

Can I make changes some info for this API key later (for example, App name and url) or I should create a new key for that?

It's really up to you how you want to design it. Sharing keys across projects means that if one key was to get suspended it would affect both. Then again, if you're not doing anything that should ever be a problem then it doesn't really matter.

How can I get more requests per day?

You can't. Keep in mind requests are limited by IP address, not API key.

I'd like to add info screen where I will add a link to your website.

Sure. You can find a list of our logos and brand information here.

I wanna add Ads to the app, is this ok? Or it is forbidden, cause I will earn money with it?

Ads are fine.

Thank you so much! =)
