Needs a birth time.

Request body

birth Birth required
- date string (date) required
  e.g. "1990-08-13"
- time string
  pattern ^([01]\d|2[0-3]):[0-5]\d(:[0-5]\d)?$ · e.g. "06:30"
- time_accuracy string
  With "unknown", lagna- and house-dependent fields are omitted and listed in warnings — never filled with a noon default.
  one of exact, approximate, unknown · default "exact"
- place Coordinates or object or object required
  Coordinates, a place_id from /v1/places/search, or a free-text query. A vague query returns 422 place_ambiguous with candidates; the API never guesses.
  
  One of:
  1. Coordinates
    Fields
    - latitude number required
      ≥ -90 · ≤ 90
    - longitude number required
      ≥ -180 · ≤ 180
    No other fields are accepted.
  2. object
    Fields
    - place_id string required
    No other fields are accepted.
  3. object
    Fields
    - query string required
      at least 2 characters · at most 120 characters
    No other fields are accepted.
- timezone string
  "auto" (from coordinates AND date), an IANA name, or a fixed offset like "+05:30".
  default "auto"
No other fields are accepted.
options Options
- ayanamsa string
  Each system is its Swiss Ephemeris definition (a constant offset from Lahiri). Applies to chart operations; KP operations always use KP-New and the personal muhurat stays Lahiri. meta.ayanamsa names the system used.
  one of lahiri, raman, krishnamurti, yukteshwar, fagan_bradley · default "lahiri"
- house_system string
  one of whole_sign · default "whole_sign"
- node string
  The Rahu/Ketu the chart uses: the true (osculating) node, as Swiss Ephemeris and Drik Panchang define it, or the mean node. meta.node names the one used. POST /v1/planets/positions always returns both.
  one of true, mean · default "true"
- lang string
  one of en, hi · default "en"
- view string
  compact drops labels and prose — for LLM callers.
  one of full, compact · default "full"
- tone string
  descriptive: the prose fields (tithi.note, tara descriptions, the timing summary and insights, natal-transit descriptions, transit-event notes) carry reviewed descriptive sentences, attributed to the tradition and with no instructions, in options.lang. Ids, scores and every other value are unchanged. Applies to getPanchang, getFavourableDays, getPersonalTiming, getDashaTransitConfluence, getNatalTransits and listPlanetaryEvents (and those inside a bundle); elsewhere it changes nothing.
  one of default, descriptive · default "default"
- dasha_year number
  Days in a Vimshottari year: 365.25 (Julian, the default), 365.2422 (tropical) or 360 (savana). Applies to /v1/dasha/vimshottari and /v1/dasha/vimshottari/current; data.basis.year_days names the one used.
  one of 365.25, 365.2422, 360 · default 365.25
No other fields are accepted.
