What does the SwissEphemerisAll API return?

It returns raw longitude, latitude, distance in astronomical units and three speed fields for the Sun, Moon, Mercury, Mars, Venus, Jupiter, Saturn, Uranus, Neptune, Pluto and entries named Rahu and Ketu.

Are the returned longitudes tropical or sidereal?

SwissEphemerisAll exposes the raw Swiss Ephemeris calculation output. The builder presents its longitude directly and derives a tropical zodiac position only as a display aid.

Can I test the Swiss Ephemeris API for free?

Yes. VedAstro provides a free tier of up to five requests per minute without an API key.

The API currently exposes its raw speed fields exactly as returned. Zero values are preserved rather than inferred or replaced.

About the SwissEphemerisAll endpoint

The endpoint is a thin API-facing wrapper around Swiss Ephemeris. It calculates the Sun through Pluto plus the returned Rahu and Ketu entries, and exposes longitude, latitude, astronomical-unit distance and the corresponding speed fields without adding an interpretive astrology layer.

Use this endpoint when your application needs low-level astronomical values. For signs, houses, aspects or chart SVGs, use VedAstro's higher-level calculation endpoints.
