Resolve a NAICS 2022 code to its industry title: Complete for the bundled 2022 vintage: all 2129 NAICS 2022 codes at levels 2 through 6, titles verbatim from the Census workbook, with the three range-spelled sectors (31-33, 44-45, 48-49) expanded to one entry per member sector. NAICS is a closed set, so a well-formed code absent from this snapshot is absent from the 2022 vintage. Refresh is a redeploy, never a live fetch.

On-chain payments
Payment shape (1 most recent sampled): 1 x402-signed (EIP-3009 transferWithAuthorization, the exact scheme's on-chain signature) · 0 plain transfers (a wallet paying the ordinary way) · 0 other calldata (facilitator batch, smart wallet, or unrelated — not classified).
Peak day 2026-09-17: 10 payments. Last indexed day 2026-10-08: 3. Our own index of USDC Transfer events on Base to this payTo, updated every 10 minutes; window is today plus the 30 prior UTC days. Base USDC only — a seller settling elsewhere reads as quiet here. These figures belong to the address, which 10 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
