Same astrology as POST /vedic/gemstones, and pinned by a test to never disagree with it: same sidereal lagna, same two schools, same three gems. What the document adds is what a table cannot carry. Every recommended gem gets a page: what the graha it belongs to signifies classically, the basis in house ownership, mineral and substitutes, weight in ratti with gram and carat conversions, weekday, finger, metal, mantra and japa count, and the next auspicious day to first wear it, found by scanning the Panchang for the nearest favourable day that falls on that graha own weekday. The school is named on the cover: the two prescribe the same gems but withhold different ones, so a document that hid which produced it would be less honest than the JSON. Coordinates are required and never defaulted. The gemmologist and physician boundary is carried verbatim from the JSON endpoint.

Section titled “Request Body required ”object
Birth data for a single natal chart. Required: date (YYYY-MM-DD), time (HH:mm:ss), latitude and longitude in decimal degrees. The short forms lat, lon, lng and tz are rejected with 400 INVALID_FIELD; pass the full names. timezoneOffset is hours from UTC and defaults to 0, meaning UTC. city is a display label only: nothing here geocodes it, so it never stands in for coordinates.
object
Hours from UTC at the given moment, not minutes. Fractional zones are hours too: 5.5 for India, 5.75 for Nepal, -3.5 for Newfoundland. Defaults to 0, meaning UTC.
Sidereal school by name. Lahiri when omitted. Equivalent to ayanamsaId; send either.
Birth latitude. Required here: the whole document is computed from it.
Birth longitude. Required here: the whole document is computed from it.
object
Accent colour, used for section heading text and inline emphasis.
Colour of the divider rule under each section heading (not the heading text, which is themeColor).
