Tools
9search_birthplace
Find disambiguated birthplace candidates and GeoNames ids for “where was I born”, “luogo di nascita”, “cerca città”. Ask the user to choose when more than one plausible match exists; never guess. No birth data is stored or logged, including request bodies, queries, access logs, stats and errors.
get_big_three
Calculate Sun sign, Moon sign and rising sign together for “what is my rising sign”, “my moon sign”, “my Big Three”, “qual è il mio ascendente”, “segno lunare”, “Sole Luna ascendente”. Returns uncertainty, one-line meanings and reference links. Ask for missing birth time and birthplace instead of guessing. If the user does not know the time, explicitly use unknown: no Ascendant or houses, and both Moon signs when applicable. No birth data is stored or logged, including request bodies, queries, access logs, stats and errors.
calculate_birth_chart
Calculate a complete natal chart for “my birth chart”, “tema natale”, “calcola tema natale”: planets, Ascendant, Whole Sign houses, major aspects, uncertainty and one-line meanings with links. Approximate times need a ±15,30,60 or 120 minute window; supports fold choice and historic offset override. Ask for missing birth time and birthplace instead of guessing. If the user does not know the time, explicitly use unknown: no Ascendant or houses, and both Moon signs when applicable. No birth data is stored or logged, including request bodies, queries, access logs, stats and errors.
get_sun_sign
Find the Sun zodiac sign from a birth date for “what is my zodiac sign”, “che segno sono”, “segno per data”. Handles cusp dates with ingress and uncertainty, never guesses; ask for timezone when supplying time. Without timezone considers all possible local-day conversions. No birth data is stored or logged, including request bodies, queries, access logs, stats and errors.
get_planet_positions
Compute the current sky or a specified ISO instant: “where is Venus today”, “where are the planets today”, “dove si trova Venere oggi”, “cielo di oggi”. Returns tropical geocentric positions, retrograde flags and Moon phase/illumination. Defaults to now and UTC. No birth data is stored or logged, including request bodies, queries, access logs, stats and errors.
get_retrograde_periods
Find retrograde periods by planet and year: “when is Mercury retrograde in 2027”, “quando è Mercurio retrogrado”. Mercury through Pluto, 1900–2099; includes stations, pre/post shadows and uncertainty windows. A station estimate is not an exact-to-the-second fact. No birth data is stored or logged, including request bodies, queries, access logs, stats and errors.
get_moon_phases
Calculate new, first quarter, full and last quarter Moon: “when is the next full Moon”, “quando è la luna piena”, “calendario lunare”. Supply from_date, to_date and IANA timezone. Date range is [from,to) UTC, max 400 days; output local times, signs and uncertainty. No birth data is stored or logged, including request bodies, queries, access logs, stats and errors.
get_sign_ingresses
Find when a planet enters a zodiac sign: “when does Venus enter Leo”, “quando entra Venere in Leone”, “ingressi nei segni”. Includes retrograde re-entries and uncertainty windows. Supply dates [from,to) UTC, max 400 days. No birth data is stored or logged, including request bodies, queries, access logs, stats and errors.
get_placement_meaning
Read the free corpus meaning of a placement: “Venus in Leo”, “Moon in the 7th house”, “rising sign Libra”, “Venere in Leone”, “Luna in settima casa”, “ascendente Bilancia”. Supply canonical English ids for body_or_angle and sign, or house 1–12. One sign or one house per call; no sign/house returns the body meaning. Interpretation is symbolic, not a scientific prediction. No birth data is stored or logged, including request bodies, queries, access logs, stats and errors.
