How this service works
Verify a company and decode an identifier, one paid fact per call: KYB lookups that resolve a legal entity by LEI, by company name or by company domain from the GLEIF Level 1 golden copy, NAICS 2022 industry titles, and structural VIN decoding. Every answer is served from bundled digest-pinned snapshots of public reference data, with the snapshot's own provenance and coverage bound beside it, and never from a live third-party fetch.
Output
Returns a JSON object containing the resolved NAICS code, its official 2022 Census Bureau industry title, numeric hierarchy level (2–6), parent code (or null for top-level sectors), vintage year (2022), plus full source provenance including snapshot name, SHA-256 digest, and coverage statement confirming completeness of the 2022 vintage.
Example use cases
Enrich business profile with industry name
“I have a company record with NAICS code 4413 — can you look up the official 2022 industry title and tell me what level it is in the classification hierarchy?”
Validate NAICS code in submitted form
“A vendor submitted NAICS code 99999 on their onboarding form — can you check whether that's a real 2022 NAICS code and if so what industry it represents?”
Decode sector code for compliance report
“Our compliance report needs the full Census Bureau industry title for NAICS code 52, including its hierarchy level and whether it has a parent code.”
Technical details
Endpoint
GEThttps://lookups.alienprobe.ai/v1/lookup/naics?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a deterministic, provenance-stamped resolution of a NAICS 2022 code to its official Census Bureau title and hierarchy metadata — especially in KYB pipelines, compliance workflows, or data enrichment where auditability (SHA-256 pinned snapshot) matters more than real-time freshness. It covers all 2129 NAICS 2022 codes authoritatively. Prefer alternatives if you need live NAICS data, non-2022 vintages, or free lookups at high volume.
Side effects
- Invalid or malformed code (not 2–6 digits): request rejected before payment
- Well-formed code not present in 2022 NAICS vintage: confirmed absent (NAICS is a closed set, so absence is authoritative)
- Payment failure via x402 protocol: call not executed
- Network timeout: retry safe since endpoint is idempotent
