Thanks for quick replies! I'll wait for free key publication.

Btw, you wrote

You should get a free key at once and either the resulting photos will be marked with out "Pho.to" watermark or your users will be redirected on our site for a while and then again returned to yours

Does it mean I'll be able to use your service on my site without any key at all (but with above limitations)?

Also, I see the platform is progressing now dramatically. It's wonderful! So, I've got a question - if I embed the product on my site now, will your changes appear on my site automatically? If no, do you plan to implement that feature? (In any case, I'm ready to update my site time to time for the best version of photo editor.)

Hi!

I liked online Photo editor.
As I understood, I can place this functionality on my own site? (is that what you call Platform?)
I was looking for such a system for a long time, so it is wonderful you can do it!

I've downloaded and learned SDK. So, I learned I should get a key to prepare POST- or GET- requests.
Also, there are two types of keys - free and paid. Free key is anough for me. Should I get it once or should my site's visitors get a key (one per visitor)? And also - how can I get it? I didn't understand it by SDK and description on pho.to site. sad
