KP Transit Chart

Endpoint POST https://starsapi.com/api/v3/vedic/kp/transit-chart

Returns a rendered KP transit chart for any moment — ready-to-embed PNG images in both North Indian and South Indian styles, drawn with Placidus (chalit) house placements per KP practice, plus the ascendant summary for the moment.

Date and time are optional — omit them entirely and the current moment at the given location is used.

Image URLs are signed and time-limited (expires + token query parameters). Fetch or embed them promptly rather than storing the URLs long-term; request the endpoint again for a fresh pair.
