Questions

Is there a free birth chart API?

Yes. Every operation, the kundli and the Western chart included, is on the Free plan. See the free astrology API.

How accurate are the positions?

We compare them with NASA JPL Horizons across 1900–2025, and publish the figures on accuracy.

Vedic or Western: which does the API use?

Both. The kundli is sidereal, with the Lahiri ayanamsa by default. The Western chart is tropical. See conventions.
