The ratna prescription as a multi-page A4 PDF (default) or live HTML (add ?format=html). 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.

Parameters

Query Parameters

fields

string

Comma-separated dotted paths, relative to data, to keep in the response. A path is applied to every element of an array, so planets.name means the name of each planet. Paths that match nothing come back in _fields_unmatched; a list where nothing matches at all is a 400, because an empty object would be a confident wrong answer.

Example

planets.name,planets.longitude

precision

integer

<= 15

Round every non-integer number in the response to this many decimal places. Integers are left alone, because an id is not a measurement. Ecliptic longitudes ship with fourteen decimals by default; 2 is about a tenth of an arcminute.

Example

Request Body^required

application/json

object

chart required

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; send timezone instead (an IANA name such as Europe/Kyiv, or auto) and the offset for that date is worked out, summer time included. city is a display label only: nothing here geocodes it, so it never stands in for coordinates. houseSystem is a single Swiss Ephemeris letter, P by default; a name such as “Placidus” is refused, and the case matters because I and i are two different Sunshine systems.

object

date required

string

/^\d{4}-\d{2}-\d{2}$/

time required

string

/^\d{2}:\d{2}(:\d{2})?$/

timezoneOffset

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. Ignored when timezone is sent.

number

0 nullable >= -14 <= 14

timezone

IANA zone name such as Europe/Kyiv, or auto to look the zone up from latitude and longitude. The server takes the offset that zone kept at this local date and time, summer time included, and uses it in place of timezoneOffset. A clock time that happened twice takes the first occurrence; one skipped when clocks went forward takes the offset from before the change. Abbreviations such as EST are refused. Before 1970 the tz database is not reliable for every place, so send timezoneOffset when the local clock is known.

string

latitude required
