Steps
Authenticate to Space-Track.org (session login) as with any basicspacedata query.
Query /basicspacedata/query/class/satcat/ with predicates such as CURRENT/Y (currently on-orbit objects only), COUNTRY, OBJECT_TYPE, or PERIOD ranges, plus /format/json.
Query /basicspacedata/query/class/boxscore/format/json for the daily country-by-country accounting of payloads, rocket bodies, debris, and total tracked objects.
Use Space-Track's documented naming conventions (e.g. 'DEB'/'COOLANT'/'SHROUD' in the common name implies debris; 'R/B', 'AKM', or 'PKM' implies rocket body) if you need to cross-check the OBJECT_TYPE field.
Known gotchas
Space-Track's usage policy limits SATCAT and BOXSCORE pulls to once per day, after 1700 UTC when that day's data is finalized — polling more frequently violates the API guidelines and risks account suspension.
SATCAT numeric RCS values are not exposed by default (only a scaled RCS_SIZE bucket of small/medium/large); numeric RCS requires an approved Orbital Data Request.
Boxscore is a daily snapshot/summary, not a live feed — don't expect intra-day updates.
