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.
