How this service works
Paid single-fact lookups, answered from bundled digest-pinned snapshots of public reference data.
Output
Returns a JSON object with the official NAICS 2022 title for the requested code, along with source attribution (US Census Bureau 2022 reference file), a snapshot SHA-256 hash for provenance verification, vintage year, and coverage notes confirming completeness across all 2129 codes at digit levels 2–6.
Example use cases
Classify a company by industry code
“I have a company filing that lists NAICS code 513210 — what industry does that actually mean in plain English according to the 2022 Census classification?”
Validate NAICS code before data submission
“Before I submit this business survey, can you confirm that NAICS code 4451 is a valid 2022 vintage code and tell me its official title?”
Enrich vendor records with industry labels
“I have a vendor record showing NAICS code 3364 — look up the official Census Bureau title for that code so I can label the record correctly.”
Technical details
Endpoint
GEThttps://lookups.alienprobe.ai/v1/lookup/naics/513210When to prefer
Choose this endpoint when you need a fast, authoritative, provenance-verified lookup of a single NAICS 2022 code title and do not need live data freshness — the snapshot is digest-pinned to a known SHA-256 hash. Prefer this over scraping Census Bureau pages or calling broader industry databases when you only need official code-to-title resolution at minimal cost ($0.004 per call). Not suitable if you need the 2017 vintage, SIC codes, or industry descriptions beyond the official Census titles.
Side effects
- Invalid or malformed NAICS code returns no match (code absent from 2022 vintage)
- 1-digit or 7+ digit codes outside the 2–6 digit range may not be found
- Codes valid in older NAICS vintages (e.g. 2017) but removed in 2022 will return no result
- Payment failure or insufficient USDC balance blocks the request
- Network timeout if the service is temporarily unreachable
