GET /icons/[icon].svg - Get an icon in SVG format (equivalent to fetching them directly from Lucide)
GET /icons/[icon].png - Get an icon rendered in PNG format
Query parameters:
-- note: Make sure to URL encode the query parameters: particularly special characters such as # (e.g. %23). The server only accepts a small subset of characters deemed necessary for the query parameters.
scale - integer - Scale the icon (default: 1, min: 1, max: 100)
padding - integer - Add padding (px) around the icon (default: 0, min: 0, max: 100)
background - hex - Set the background color in hex w/o the hashtag (e.g. FFFFFF) (default: transparent)
background - hex - Set the background color in hex WITHOUT the hashtag (e.g. FFFFFF) (default: transparent)
stroke_color - string - Set the stroke color for the SVG icon, any CSS color WITH the hashtag (default: currentColor)
discord_compatibility - boolean - Set padding to 8px for Discord compatibility. Typically for use in embed author icons as these have a circle clip applied by Discord. Overrides padding if set. (default: false)
cache_key - string - Technically this can have any name. The server does not interpret this at all. Useful for cache busting. (default: none)
