I’m building a Flickr widget for our new theme and I have stumbled upon the following:
To use the Flickr API you need to have an application key. We use this to track API usage.
Currently, commercial use of the API is allowed only with prior permission. Requests for API keys intended for commercial use are reviewed by staff. If your project is personal, artistic, free or otherwise non-commercial please don’t request a commercial key. If your project is commercial, please provide sufficient detail to help us decide. Thanks!
Now I know, I’ve seen Flickr widgets around here, the question is: am I allow to use the API key within the preview of a theme? does this require a commercial key?
