Alien Probe — NAICS 2022 code lookup

● verified · data.reference · 0.004 USDC/call · base

Resolve one NAICS 2022 code (levels 2-6) to its official US Census title. Complete closed set: all 2,129 codes, titles verbatim from the Census workbook, served from a digest-pinned bundled snapshot (source, vintage and snapshot_sha256 in every response). Deterministic and keyless; a malformed or absent code is refused free before the payment boundary, never guessed. x402 v2 exact scheme, USDC on Base mainnet, no signup.

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.
