Measured tools (9)

• search_birthplace read-only

  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.

  Parameters:

  • query (required) — string
  • lang — string — Language code. Published: en, it. Other codes fall back to English with a language.note.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_big_three read-only

  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.

  Parameters:

  • birth_date (required) — string
  • time_precision (required) — string
  • lang — string — Language code. Published: en, it. Other codes fall back to English with a language.note.
  • latitude — number
  • place_id — integer
  • timezone — string
  • ambiguity — string
  • longitude — number
  • birth_time — string
  • approx_window_minutes
  • utc_offset_override_sec — integer

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• calculate_birth_chart read-only

  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.

  Parameters:

  • birth_date (required) — string
  • time_precision (required) — string
  • lang — string — Language code. Published: en, it. Other codes fall back to English with a language.note.
  • latitude — number
  • place_id — integer
  • timezone — string
  • ambiguity — string
  • longitude — number
  • birth_time — string
  • approx_window_minutes
  • utc_offset_override_sec — integer

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_sun_sign read-only

  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.

  Parameters:

  • birth_date (required) — string
  • lang — string — Language code. Published: en, it. Other codes fall back to English with a language.note.
  • timezone — string
  • birth_time — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_planet_positions read-only

  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.

  Parameters:

  • lang — string — Language code. Published: en, it. Other codes fall back to English with a language.note.
  • datetime — string
  • timezone — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_retrograde_periods read-only

  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.

  Parameters:

  • planet (required) — string
  • year (required) — integer
  • lang — string — Language code. Published: en, it. Other codes fall back to English with a language.note.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

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.

  Parameters:

  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-only

  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.
