Methodology and astrological context for Horoscope Chart Extended.
The Horoscope Chart Extended API is the enriched variant of the Horoscope Chart endpoint. It generates a Vedic astrology horoscope chart for a given birth profile and chart type, and returns a significantly more detailed data payload than the standard chart endpoint — including deeper planetary attributes, additional astronomical data, and richer contextual information for each placement. It supports the same comprehensive set of divisional charts (Vargas) and special charts as the base endpoint.
This endpoint accepts a person's birth date, time, and geographic coordinates, along with a chartId path parameter specifying which chart to generate. It performs the same core astronomical computation as the Horoscope Chart endpoint — calculating planetary positions, house cusps, and sign placements for the requested chart type — but returns an extended response with additional layers of detail for each planet and house.
The /extended suffix distinguishes this endpoint from the standard chart endpoint: where the base endpoint returns a concise chart representation suitable for rendering, this endpoint returns a richer dataset designed for in-depth analysis, detailed report generation, or applications that need to display comprehensive astrological attributes alongside the chart.
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.
In addition to the core chart data returned by the standard Horoscope Chart endpoint, the extended response provides enriched attributes for each planetary placement, which may include:
chartId path parameter, covering all major Varga divisional charts (D1 through D150), the Chalit chart, Moon chart, and Sun chart — identical chart type coverage to the base endpointX-Ayanamsha header, supporting multiple Vedic traditions (e.g., Lahiri, Krishnamurti, Raman)Accept-Language header for localised planet, sign, and nakshatra nameschartId, without altering the birth data payloadPayload specifications for JSON request body.
