The /bazi/chart reading as an A4 PDF (default), HTML or Markdown: the four pillars with stems, branches, animals, ten gods, hidden stems, na yin and the twelve stages; the day master with its classical image; the five elements counted three ways; the strength verdict with favourable elements and its stated thresholds; the symbolic stars; the branch interactions; and the ten-year luck pillars when gender is given. Takes the /bazi/chart birth input (date, time, timezoneOffset or timezone, longitude with trueSolarTime, dayBoundary), plus name and city for the cover. No AI. Texts in Ukrainian or English; any other language gets the English document.

Parameters

Query Parameters

retain_days

integer

default: 1 >= 1 <= 90

How many days the PDF stays at its url. 1 by default; up to 90 for a link you hand to a client. Delete it sooner with DELETE /v1/reports/files/{filename}.

format

string

default: pdf

Allowed values: pdf html markdown

Same switch as the format body field (send one or the other; two different values are a 400). pdf stores a PDF and answers with its url. html returns one self-contained text/html document (inline CSS and drawings, no scripts, no external fonts; the white-label logo stays a link to your https image). markdown returns text/markdown with the same headings, text and tables, drawings left out with a one-line note. Neither html nor markdown is stored, so retain_days does not apply. Same price in every format.

fields

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.

Example

planets.name,planets.longitude

precision

integer

<= 15

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.

Example

Header Parameters

Idempotency-Key

string

>= 1 characters <= 255 characters /^[\x21-\x7E]+$/

Unique per logical operation, kept across retries. For 24 hours from the first request, a repeat with the same key, method, path, body and query string returns the stored response with Idempotent-Replayed: true and costs 0 credits. The same key with a different body or query string is a 409 IDEMPOTENCY_KEY_REUSED; a repeat while the first is still running is a 409 IDEMPOTENCY_IN_PROGRESS. Only 2xx responses are kept. See /idempotency/.

Example

01HXY2A7ZM0ABCDEF

Request Body^required

application/json

object

date required

string

/^\d{4}-\d{2}-\d{2}$/

time

string

/^\d{2}:\d{2}(:\d{2})?$/

timezoneOffset

Ignored when timezone is sent.

number

>= -14 <= 14

timezone

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.

string

longitude

number

>= -180 <= 180

trueSolarTime

boolean

dayBoundary

string

Allowed values: 23:00 midnight

stageSchool

string

Allowed values: classical unified

gender

Allowed values: male female

name

Printed on the cover.

string

<= 100 characters

city

Printed on the cover; the chart is read from date, time, zone and longitude.

string

<= 120 characters

language

string

Allowed values: uk en de ru pl es pt hi fr ko it ja id tr nl ro cs vi ar el hu

whitelabel

Any of:

boolean

format

pdf (default) stores a PDF and answers with its url. html returns one self-contained text/html document, markdown returns text/markdown with the same sections and tables; neither is stored. Same price in every format.
