Filter by name (q, e.g. "starlink"), owner/launching country (owner — code like US/PRC/CIS or a name like "china"), object type (type = payload | rocket body | debris | unknown), launch-year range (launchYearFrom/launchYearTo), international/COSPAR designator prefix (intlDesignator, e.g. "2024-"), on-orbit vs decayed (onOrbit), or exact NORAD number (noradId). Each result carries the NORAD id, name, international designator, object type, owner + resolved country, launch date + site, decay date (null = still in orbit), and orbital parameters (period, inclination, apogee, perigee). The envelope total is the full count matching your filter — so onOrbit=true&type=payload answers "how many active satellites are up there", and owner=PRC tells you who launched them.
