# Industry and Occupation Codes – NAICS/SOC Cross-Walk

> Industry and Occupation Codes – NAICS/SOC Cross-Walk is a paid API for AI agents from industry-occupation-codes.x402tookit.com, paid per call via x402, $0.03/call, status unknown (last checked 2026-11-02).

Given a NAICS industry code, returns its top SOC occupations by employment share; given a SOC occupation code, returns its top employing industries — drawn from the BLS employment matrix.

## 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 industry-and-occupation-codes-naics-soc-cross-walk-81da1d1d
```

Example prompt: Using the BLS employment matrix crosswalk, what are the top 10 occupations in the retail trade industry — NAICS code 44?

## When to prefer this

Use this endpoint when you need to bridge between industry classifications and occupational classifications using authoritative BLS employment matrix data — specifically for workforce analysis, labor market research, staffing modeling, or any application that needs to understand what occupations dominate a given industry or which industries absorb a specific occupation. Prefer this over generic search endpoints when you have a concrete NAICS or SOC code and need ranked, employment-weighted crosswalk results.

## Known failure modes

- Invalid or unrecognized NAICS/SOC code returns a non-match verdict with reasons
- Neither naics nor soc query parameter provided results in an error
- Code level too granular to match BLS matrix industries may return degraded or partial results
- Limit out of range (below 1 or above 30) may be rejected or clamped
- Truncated or partial codes may partially match at a broader level with a degraded flag

## How this service works

Link a NAICS industry to its top SOC occupations, or a SOC occupation to its top industries, from the BLS employment matrix.

## Output

Returns a structured object including: the resolved NAICS or SOC code and title, a list of top occupations (for NAICS input) or top industries (for SOC input) each with SOC/NAICS code, title, estimated 2025 employment in thousands, and share-of-industry employment percentage; plus metadata like matrix edition, match mode, direction, summary narrative, and attribution/disclaimer text.
