A wheel chart is the round drawing of a birth chart. It shows the 12 signs, the 12 houses and each planet in its place. Drawing one well takes a lot of work, so our Wheel Chart API draws it for you.
Send the birth details and your style choices. We return a link to the finished chart image. SVG stays sharp at any size, and PNG works anywhere an image does.
If you would rather draw the chart yourself, use our chart data endpoints. We can also design a custom chart theme that matches your brand.
A chart_url that points to the drawn wheel, plus a status flag and a message.
Set image_type to choose the file format.
Set chart_size to fit your layout, such as 500.
Choose colours for planet icons, sign icons, the sign ring and the inner circle.
Pass house_type, such as placidus, to set how the houses are split.
Houses, planets and aspects as JSON, for teams that draw their own wheel.
All three are POST calls with day, month, year, hour, min, lat, lon, tzone and house_type. The image call adds the style fields. Samples are trimmed from our docs.
