Authenticate with the X-Api-Key header; without one the answer is 400 MISSING_KEY. The ?key= query parameter still works but is deprecated and answers carry a Deprecation header: a URL ends up in access logs, CDN logs and browser history, so a key passed that way stops being secret.

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.
