Brand variant

Set variant=brand to get a complete 3:2 SVG surface with a curated background and a logo treatment selected for the brand. Multicolor marks stay multicolor where that is distinctive; monochrome treatments are used where they produce a cleaner, more legible card.

Primary brand color

Append /color to any brand or alias to get one representative primary color as an uppercase six-digit hex value in a plain-text response. For example, Visa returns #1434CB.

curl https://cardmark.aspekt.systems/visa/color

const response = await fetch("https://cardmark.aspekt.systems/visa/color");const primaryColor = await response.text();

Theme metadata

Append /theme to retrieve the curated background, an accessible foreground color, and the selected logo treatment as JSON. The background can differ from the primary color—for example, Mastercard uses its red as /color while its themed card uses a dark neutral surface behind the red and orange mark.

curl https://cardmark.aspekt.systems/visa/theme

const response = await fetch("https://cardmark.aspekt.systems/visa/theme");const theme = await response.json();// { background, foreground, logoVariant }

Visa response

{  "background": "#1434CB",  "foreground": "#FFFFFF",  "logoVariant": "monochrome-light"}
