Look up or search NAICS 2022 industry classification codes (US Census Bureau, public domain). Pass `code` for an exact NAICS code — 2–6 digits or a combined sector like 31-33 — and get its official title, hierarchy path, full official description, activity index terms, and direct child codes. Or pass `query` for free-text search (e.g. 'software publishers', 'coffee shop') over titles plus the official ~20k-entry activity index → ranked candidate codes, optionally filtered by `level` (2=sector … 6=national industry). Ground truth for industry coding in KYC, business registration, government filings, and ERP vendor/customer setup.

Search the catalog of every cataloged Earth-orbiting object — ~69,000 satellites, rocket bodies, and debris tracked by US Space Force / 18 SDS (via CelesTrak SATCAT). 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. For a satellite's live sub-point position, pass its noradId to /api/space/satellite.
