# Symbolic stars (Shen Sha)

`POST /bazi/symbolic-stars`

## Request

- Base URL: `https://api.astroway.info/v1`
- URL: `https://api.astroway.info/v1/bazi/symbolic-stars`
- Auth: API key in header `X-Api-Key`

Peach Blossom, Travelling Horse, Canopy, Heavenly Nobleman, Blade and Void, computed from BOTH the year and the day reference pillar because the transmissions disagree about which one the rules read from. Where two transmissions place a star differently, both placements ship and each names the other.

## Query parameters

- `fields` string
- `precision` integer

## Request body

- BaziChartInput
  - `date` string, required
  - `time` string
  - `timezoneOffset` number: Ignored when timezone is sent.
  - `timezone` string: 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.
  - `longitude` number
  - `trueSolarTime` boolean
  - `dayBoundary` '23:00' | 'midnight'
  - `language` string
  - `stageSchool` 'classical' | 'unified'
  - `includeFullTable` boolean
  - `includeLuck` boolean
  - `gender` 'male' | 'female'
