What you can build

Drop-in UI components & widgets

Render Kundli API responses without building charts yourself. Install the npm package and drop these into Next.js, React, Vue, Svelte, Angular, or plain HTML, or embed the very same component on Squarespace, Wix, or WordPress by pasting one snippet, with no backend and no build step. They belong to one library that covers the entire spiritual stack rather than astrology alone, MIT licensed and included in every plan at no extra cost, never a separate product and never an upsell. The Kundli API calculations, the interface that renders them, and the Remote MCP your agent calls, all behind one key, end to end.
