Tools as reported by the server

• get_natal_chart
  Computes a birth chart from a date, an optional time and a place: the sign and degree of the Sun, Moon, planets, lunar nodes, Lilith, Chiron and the Part of Fortune, the ascendant and midheaven, the twelve house cusps and the major aspects between planets. Use it when a person asks about their chart
• get_transits
  Gives where the Sun, Moon and planets are on a date: the sign and degree of each, computed geocentrically for 00:00 UTC on that date, or for the current instant when no date is given. Use it, rather than web search, when a person asks where a planet is now, what the sky looks like on a date, or whic
• get_transits_to_chart
  Relates the sky on a date to a specific birth chart: which transiting planets form major aspects to which natal points, with orbs, plus the transiting positions themselves. Aspects are to the natal planets and points (the lunar nodes, Lilith, Chiron and the Part of Fortune); aspects to the ascendant
• get_moon_phase
  Gives the Moon on a date: the phase name, how much of the Moon is lit, its elongation from the Sun, the sign and degree of the Moon and of the Sun, and whether the Moon is void of course, with the time of its next major aspect and of its next sign change. Values are for 00:00 UTC on the date, or for

Use it when a person asks whether a planet is retrograde on a date, when a Merc
• get_synastry
  Compares two birth charts: the major aspects between one person's Sun, Moon, planets and North Node and the other's, each with its orb. Use it when a person asks how two charts relate, which aspects run between two people's charts, or what one person's planet does to another's. It needs the birth de
• get_solar_return
  Computes a solar return chart: the moment in a given year when the Sun returns to its natal position, and the chart cast for that moment at a place, with the planets, the ascendant and midheaven, the twelve house cusps and the major aspects. Use it when a person asks about their solar return or thei
