Seven stems are agreed across traditions; for the three that are not (戊 庚 壬) every school reading ships in schoolVariants, and school switches the headline answer.

Section titled “Authorizations ”Parameters
Section titled “ Parameters ”Query Parameters
Section titled “Query Parameters ”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.longitudeRound 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
4Request Body required
Section titled “Request Body required ”object
Ignored when timezone is sent.
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.
Example
{ "date": "1990-06-15", "school": "zhongzhou"}Responses
