## 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-industry-code-search-12eaca1d
```

Example prompt: Search for NAICS 2022 codes matching 'full service restaurants' and show me only the 6-digit national industry level results, up to 10 matches.

## When to prefer this

Use this endpoint when you need to search NAICS 2022 codes by descriptive keywords or a known code prefix — ideal for classifying businesses, tagging records, or populating dropdowns. Prefer over the validation or hierarchy endpoints when you don't already know the exact code and need fuzzy keyword discovery.

## Known failure modes

- Missing required 'q' parameter returns an error
- Query with no matching codes returns empty matches array
- Level filter outside valid range (2-6) may return no results
- Limit exceeding 50 is capped at 50
- Degraded mode may return partial results if upstream Census data is unavailable

## How this service works

Search NAICS 2022 industry codes by words in the title or a code prefix; optional level filter; capped at 50.

## Output

Returns a list of matching NAICS 2022 entries, each with a code, title, numeric level (2–6), level name (sector/subsector/group/industry/national industry), and a match score. Also includes total match count, whether results were truncated, the data source attribution, and query echo.
