Hello,
I am developing an android application, which uses the webcam API and I would like to use the free version.
I would like to make sure I fulfill the conditions correctly, because they are not entirely clear to me, therefore I have a few questions:

• should I cache the image urls for the 15 minute period when they are available or is it okay to just send a request for it everytime the image is needed?
• is the "Link or embed" condition fulfilled by placing a direct link to the image asset on your server below the image I received? Or is it just about displaying the result of the request and actually not caching anything?

And a question about general usage:

• is there a way to sort by distance i.e. to get the closest webcam possible?

Sincerely,
Jakub
