How can I get the SVG’s for icons?

It sounds like you are currently on the free (Playground) API plan. With the free plan, you only get access to icon_url (the SVG URL) for public domain icons. Having a paid API key would give you access to the SVG URL for every icon, not just the public domain.

If you are on a paid API key and still having difficulty accessing SVGs, please verify that you are adding the query string “?include_svg=1” at the end of your icon search requests.
