Description
Astronomy calculations for any place and date: sun and moon rise/set times, planet positions and visibility, Mercury and Venus apparition events, solar and lunar eclipses, lunar phases, dark-sky observing windows, and place lookup. Eleven tools over a 29-endpoint REST API, covering 1700-2200. Streamable HTTP, no install. Tool calls need a CycleCalcs API key from RapidAPI (the Basic plan is free); browsing the tool list needs nothing. Astronomy, not astrology.
