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.

# Use an x402 client with a matching signer. To see the terms first, for free:
import httpx
r = httpx.get("https://2s-jwnd2jdga-alleyford.vercel.app/api/business/naics")  # HTTP 402 + machine-readable payment terms
print(r.status_code, r.json())

# 1) An unpaid request returns HTTP 402 with the exact payment terms:
curl -i "https://2s-jwnd2jdga-alleyford.vercel.app/api/business/naics?limit=3&query=software publishers"

# 2) Paying + retrying requires an x402 client that can sign the USDC
#    authorization (curl alone cannot). See the JS / Python tabs below.
