# Lal Kitab: Planet-in-house effect

`POST https://api.astroway.info/v1/vedic/lal-kitab/planet-house-effect`

Short summary of a (planet, house) placement per LK. Caller passes `planet` (0..6, 11=Rahu, 100=Ketu) and `house` (1..12). Currently Sun-only full data; remaining 8 planets are placeholder text; the full 144-cell reading database is a Phase 3 content task.

Group: Vedic. Auth: `X-Api-Key` header. Operation ID: `vedic_lal-kitab_planet-house-effect`.

## Parameters

| Name | In | Required | Type | Description |
|---|---|---|---|---|
| `fields` | query | no | 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. |
| `precision` | query | no | integer | 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. |

## Request body

| Field | Type | Required | Description |
|---|---|---|---|
| `planet` | integer | yes |  |
| `house` | integer | yes |  |

```json

  "planet": 0,
  "house": 1
