Question 1

What does the Western astrology API cover?

Accepted Answer

It covers Western tropical astrology: synastry, composite and Davison charts, transits, secondary progressions, solar returns, astrocartography and essential dignities — all returned as structured JSON.

Question 2

What is the difference between synastry, composite and Davison charts?

Accepted Answer

Synastry compares two charts inter-aspect by inter-aspect; a composite chart is the midpoint chart of two people; and a Davison chart is a real time-space midpoint chart. The API returns all three for relationship analysis.

Question 3

Is the Western system separate from Vedic and KP?

Accepted Answer

Yes. Vedika keeps the Western (tropical), Vedic and KP systems fully isolated, so tropical zodiac calculations never mix with sidereal ones.

Question 4

How accurate are the Western chart calculations?

Accepted Answer

Positions are computed by the XALEN Ephemeris, Vedika's own engine open-sourced under Apache-2.0 and validated against reference ephemerides including JPL DE440, with a 5-million-chart test finding zero charts deviating beyond 0.1 degree.

Question 5

Can I try the Western astrology API live?

Accepted Answer

Yes. Every endpoint has a free sandbox you can call without an API key, with live demos in 12 languages. Paid plans start at $12 per month.
