# Chart Calculate

`POST /chart/calculate`

## Request

- Base URL: `https://jyotish-api.bda.ai` (the document declares no server; this is the origin it was published from)
- URL: `https://jyotish-api.bda.ai/chart/calculate`
- Auth: none declared

Compute Janma Kundali — Lagna, Rashi, Nakshatra, planets, doshas.

The full Janma Kundali (Lagna/Rashi/Nakshatra + 9-graha block + houses +
doshas + divisional charts) is a real, multi-KB client payload, so the
response is gzip-negotiated via the audited ``_json_response_maybe_gzip``
helper: the DECOMPRESSED body is byte-identical to the old
``return _attribution_envelope(result)`` path (no contract/field/value
change), and clients that do not advertise ``Accept-Encoding: gzip`` (or
tiny payloads) get the unchanged JSON body.
