# NAICS 2022 Code Lookup

> NAICS 2022 Code Lookup is a paid API for AI agents from industry-occupation-codes.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-11-02).

Returns the title, hierarchical level, and full parent chain for a given NAICS 2022 industry code (2–6 digits or sector range).

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability naics-2022-code-lookup-a1ab3d9b
```

Example prompt: What is NAICS code 541511 called, what level is it, and what are its parent industries all the way up to the sector?

## When to prefer this

Choose this endpoint when you need authoritative NAICS 2022 code-to-title resolution with full hierarchical context (parent chain, level name) sourced directly from Census Bureau data. Prefer it over manual lookups or scraped data when you need structured, machine-readable hierarchy for enrichment, validation, or directory building. Use when you have a specific code and need to decode it — for keyword-based discovery, prefer the NAICS search endpoint instead.

## Known failure modes

- Invalid or non-existent NAICS code returns a null result or error verdict
- Code outside the 2–6 digit range or malformed input returns a validation error
- Sector range codes (e.g. 31-33) may not resolve if format is not matched exactly
- Payment failure (402) if x402 micropayment is not completed
- Upstream Census Bureau data unavailable returns a degraded response flag

## How this service works

NAICS 2022 code to title, level (sector to national industry) and full parent chain. Census Bureau data.

## Output

Returns the code, its human-readable title, numeric level (2=sector through 6=national industry), level name (e.g. 'subsector', 'industry group'), number of child codes, and an ordered parent chain array — each parent including its own code, title, level, and level name — plus attribution and data source metadata.
