Rules of the road

Free forever, no signup. Use the widgets on as many pages as you like, including commercial sites.

Keep the attribution link. It keeps the data free. The widgets display the branding inside the frame regardless, but the link is what keeps this sustainable.

No modification of the data. Embed as-is — the numbers refresh on their own.
