Methodology and astrological context for Horoscope Chart Image.
The Horoscope Chart Image API renders a fully customisable Vedic astrology horoscope chart as an image for a given birth profile and chart type. Unlike the standard Horoscope Chart and Horoscope Chart Extended endpoints — which return structured data — this endpoint is purpose-built for visual output, accepting a rich set of styling parameters that control every aspect of the chart's appearance. It supports the same comprehensive range of divisional charts (Vargas) and special charts as the rest of the chart family.
This endpoint accepts a person's birth date, time, and geographic coordinates alongside a chartId path parameter specifying which chart to render. It computes the planetary positions and house placements for the requested chart type, then renders the result as a chart image using the visual configuration provided in the request body.
The caller has full control over the chart's visual presentation: chart style (North Indian, South Indian, or East Indian layout), background colour, inner and outer line colours and widths, sign and planet colours, chart size, font sizes for signs and planets, and whether signs and planets are displayed as symbols or text labels. This makes the endpoint suitable for embedding directly into web pages, mobile apps, PDF reports, or any interface that requires a ready-to-display chart image.
The chart type is controlled by the chartId path parameter, supporting the full range of divisional charts from D1 through D150, as well as the Moon chart, Sun chart, and Chalit chart. The Ayanamsha system is configurable via the X-Ayanamsha header, and multi-language output is supported via the Accept-Language header.
The response delivers a rendered chart image for the requested chart type and birth profile, with the visual appearance determined by the styling parameters supplied in the request body. The output may include:
