Planets (grahas)
Rahu in Vedic astrology

Rahu: how the API computes it
Chart endpoints use the true node. That is the actual point where the Moon's orbit crosses the Sun's path. The other choice, the mean node, is a smoothed average.
The meta block of each response says which one was used. Rahu and Ketu are always reported as retrograde (moving backward), because tradition treats them that way. But the speed field keeps their real motion (CH-10). They rule no sign and are never combust (weakened by being close to the Sun).
In the API's tables, Rahu is exalted (strongest) in Taurus and debilitated (weakest) in Scorpio (CH-02, CH-03). Schools disagree on whether the nodes aspect, or influence, other houses. The API gives them the 5th, 7th and 9th.
POST /v1/aspects takes nodes=false to leave them out (AS-05). The nodes play no part in shadbala, the six-part strength score (SB-08).

Each line is quoted from the reference page of the endpoint named above it.
- POST /v1/planets · Planet positions and the ascendantRahu and Ketu have no friends or enemies, so they report neither.

How we check the numbers
Every value here starts from planet positions worked out from NASA JPL planet data (DE440). We test them against NASA JPL Horizons, NASA's planet position service. On 25,571 positions from 1850 to 2149, the Sun and planets agree within 0.001 arc seconds. The Moon agrees within 0.011. On 2,000 random birth charts, the rising sign agrees with Swiss Ephemeris within 0.004 arc seconds. An arc second is 1/3,600 of a degree. A practicing astrologer reviews the rules behind these answers. See how we test.
