Integration details
Description
Naelos.ai gives Claude accurate astrology calculations instead of estimates. It is built on Naelos Ephemeris, an open-source engine computed from NASA JPL's DE440 and DE441 ephemerides, matching JPL to within 0.02″ across 1550–2649 and checked against JPL Horizons from 9000 BC to AD 9000. Ten read-only tools cover birth charts in nine house systems, the sky at any moment, a planet's position at any date in 15,000 years, exact transits to a chart, synastry, solar and lunar returns, progressions and solar arcs, ingresses, lunations, retrograde stations, eclipses, and Naelos's 198 researched national charts and 19 empire charts. Every answer comes in plain English and JSON, names its source, and links to the full chart on naelos.ai. Birth data is used only for the calculation and is never stored.
