How this service works
Western natal astrology only: tropical planet placements by sign and degree with retrograde flags, Whole-Sign houses, the Ascendant and Midheaven angles and the major Ptolemaic aspects. Give a birth date, and for the angles a time, place and tz or utc_offset. Deterministic ephemeris, no LLM, no keys.
Output
A JSON object containing tropical planet placements (sign, degree, retrograde flag) for all major planets, Whole-Sign house assignments, Ascendant and Midheaven angles, and major Ptolemaic aspects (conjunction, sextile, square, trine, opposition) — all computed deterministically from Swiss Ephemeris or equivalent, with no AI fabrication.
Example use cases
Find rising sign and Midheaven
“I want to know my rising sign and Midheaven — I was born on March 3, 1985 at 11:45 PM in London, UK. Can you pull up my Ascendant and Midheaven angles using the Europe/London timezone?”
Identify retrograde planets at birth
“Which planets were retrograde when I was born? My birthday is September 22, 1995 and I was born at 2:15 PM in Los Angeles, USA — please use the America/Los_Angeles timezone and show me any retrograde flags in my natal chart.”
Check Venus sign and natal aspects
“Can you tell me what sign my Venus is in and show me all the major aspects in my natal chart? I was born on July 8, 1978 at 6:00 AM in Paris, France — please use the Europe/Paris timezone.”
Technical details
Endpoint
GEThttps://api.agentstools.dev/personality/westernWhen to prefer
Use this endpoint when you need only western tropical natal astrology (planet signs/degrees, Whole-Sign houses, Ascendant, Midheaven, Ptolemaic aspects) without Vedic or Chinese systems — it is cheaper and simpler than the multi-framework sibling endpoint. Prefer it for birth chart lookups, rising sign detection, retrograde identification, and aspect analysis using classical Western methods. It requires no API key and is fully deterministic.
Side effects
- Missing required 'date' parameter returns a 400 error
- Unrecognizable birth place text fails geocoding and returns an error
- Providing time without place or coordinates returns angles as unavailable
- Invalid date format (not YYYY-MM-DD) causes a parsing error
- Unknown IANA timezone name causes a tz resolution error
- Ambiguous place names may resolve to an incorrect location
