Build a Western birth chart

A tropical natal chart in your app: positions, houses, aspects, the chart's balance, a wheel image and a written reading.

The chart

curl https://api.96astroapi.com/v1/western/western-natal-chart \
  -H "Authorization: Bearer $ASTRO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "datetime": "1990-10-18T14:30:00", "timezone": "Asia/Kolkata", "latitude": 28.6139, "longitude": 77.209 }'

You get:

  • big_three: the Sun, Moon and rising signs, for a headline.
  • planets: each planet's sign, degree, house, dignity and retrograde state.
  • houses and aspects, with the tightest aspects first.
  • chart_signature: how the planets are spread.

The chart's balance

chart_signature makes a good summary screen:

  • elements and modes: a count and a percentage for each, with the dominant one. Each of the ten planets counts once.
  • dominant_signs: the signs holding the most planets.
  • hemispheres: how many planets are in the east and west, and north and south, and which way the chart leans.
  • moon_phase: the Moon's phase at birth, with its angle from the Sun.

Drawing it

western-natal-wheel returns the wheel as an image, ready to show. You do not need a chart library.

Adding words

  • western-planet-readings: each planet in its sign and house.
  • western-house-readings: each house from its sign and ruler.
  • western-personality-report: a whole personality reading.
  • western-detailed-report: everything, and it can also become a PDF or an MP3.

Settings

Send "house_system": "K" for Koch, "W" for whole sign or "E" for equal. The default is Placidus. Vertex, Lilith, Part of Fortune and the asteroids are in western-extra-points.
