2s.io NAICS 2022 Industry Classification Lookup & Search is a paid API for AI agents from 2s.io, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).
Look up a specific NAICS 2022 code or free-text search for industry classification codes, returning official titles, hierarchy, descriptions, and activity index terms
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.
Returns either: (lookup mode) the official NAICS title, full hierarchy path, official description, activity index terms, and direct child codes for the given code; or (search mode) a ranked list of candidate NAICS codes with titles and relevance scores, optionally filtered to a specific level (sector through national industry).
GEThttps://2s.io/api/business/naicsUse this endpoint when you need authoritative NAICS 2022 classifications for KYC, business registration, government filings, ERP vendor/customer setup, or any context requiring ground-truth US industry coding. Prefer this over generic web search when you need structured hierarchy, official descriptions, and the Census Bureau's full 20k-entry activity index for precise code matching.
