/v1/chart/houses

Whole-sign house cusps.

What this tells you

By default this endpoint uses whole-sign houses, the usual Vedic method: each zodiac sign is one house, starting from the ascendant's sign, so every cusp falls at 0° of a sign. Pass `house_system=placidus` (or koch, equal, campanus, porphyry and others) to get computed cusps instead. The bhava lord of each house is its sign lord; where that lord sits in the chart (another house) is the basis of many yogas.

Request

All requests require an Authorization header with your dv_live_* API key.

example request

curl "https://api.lifeastroapi.com/v1/chart/houses?date=1990-01-15&tz=Asia%2FKolkata&lat=19.076&lon=72.8777&time=10%3A30" \
  -H "Authorization: Bearer YOUR_API_KEY"

Query parameters

Checked against the API: a parameter is marked required when the request fails without it.

Name	Required	Example	Description
`date`	yes	`1990-01-15`	Birth date (YYYY-MM-DD).
`tz`	yes	`Asia/Kolkata`	Birth place timezone: IANA name (Asia/Kolkata) or UTC offset (+05:30).
`lat`	yes	`19.076`	Birth place latitude in decimal degrees.
`lon`	yes	`72.8777`	Birth place longitude in decimal degrees.
`time`	no	`10:30`	Birth time (HH:MM, 24-hour, local). Defaults to 12:00.
`ayanamsa`	no	—	Ayanamsa (sidereal offset) to use. Defaults to lahiri.

Field reference

Every field in the response, with its type, a real example, and what it means.

Field	Type	Meaning
date	string	Birth date you sent (YYYY-MM-DD), echoed back. example: `"1990-01-15"`
time	string	Birth time you sent, echoed back. "12:00" when you leave `time` out. example: `"10:30"`
tz	string	Timezone you sent (IANA name or fixed offset such as +05:30), echoed back. example: `"Asia/Kolkata"`
location	object	Birth coordinates used. `alt` is in metres and is 0 unless you send `alt`. example: `{ "lat": 19.076, "lon": 72.8777, "alt": 0 }`
ayanamsa	string	Ayanamsa used. Default lahiri; set it with the `ayanamsa` parameter (lahiri, raman, krishnamurti, fagan, yukteshwar, true_chitrapaksha). example: `"lahiri"`
ayanamsa_value	number	Ayanamsa in degrees at the birth moment. Sidereal longitude = tropical longitude − this value. example: `23.71795`
house_system	string	House system used for the cusps in `houses`. Default whole_sign; set it with the `house_system` parameter (placidus, koch, equal, campanus, porphyry and others). example: `"whole_sign"`
ascendant	object	The lagna. Same object and fields as /v1/chart/ascendant. example: `{ "sidereal_lon": 326.391667, "sign_index": 10, … }`
houses[]	array of 12 objects	The 12 houses, always in order 1 → 12. example: `[{ "house": 1, … }, …]`
houses[].house	integer (1–12)	House number. example: `1`
houses[].cusp_lon	number (0–360)	Sidereal longitude where the house starts. Whole-sign: the start of the sign (sign_index × 30). Other house systems: the computed cusp. example: `300`
houses[].sign_index	integer (0–11)	Sign of the cusp: 0=Aries, 1=Taurus, …, 11=Pisces. example: `10`
houses[].sign_lord	string	Ruler of that sign — the bhava lord of this house. Translated with `locale`. example: `"Saturn"`
houses[].deg_in_sign	number (0–30)	Degrees of the cusp inside its sign. Always 0 for whole-sign houses. example: `0`
houses[].dms_in_sign	string	Degrees, minutes and seconds of the cusp inside its sign. example: `"00°00'00\""`

Usage tips

How to use it

KP cusps and sub lords
This endpoint has no star or sub lords. For KP (Placidus) cusps with star, sub and sub-sub lords, call /v1/chart/kp-house-significator.
Bhava lord placement analysis
Cross-reference each `sign_lord` with /v1/chart/planets — "Where is my 10th lord?" → take `houses[9].sign_lord`, then read that planet's `house`.
Planet houses stay whole-sign
Changing `house_system` changes the cusps here only. The planet `house` numbers in /v1/chart/planets and the other chart endpoints are always whole-sign.
