Example prompt: What's the official Census Bureau title for NAICS code 541511 under the 2022 standard?

## When to prefer this

Choose this endpoint when you need a fast, authoritative, offline-safe lookup of any NAICS 2022 code title — especially when you need full coverage of all 2129 codes including the tricky range-spelled sectors (31-33, 44-45, 48-49). Prefer this over scraping the Census Bureau website or maintaining your own NAICS table, and when you need consistent, reproducible results tied to a specific vintage year.

## Known failure modes

- Code not found: well-formed code absent from 2022 vintage returns a not-found response indicating it is not part of the standard
- Malformed code: non-numeric or out-of-range input returns a validation error
- Data staleness: snapshot is pinned to 2022 vintage and will not reflect future NAICS revisions until a redeploy occurs

## How this service works

single-fact naics lookup. Complete for the bundled 2022 vintage: all 2129 NAICS 2022 codes at levels 2 through 6, titles verbatim from the Census workbook, with the three range-spelled sectors (31-33, 44-45, 48-49) expanded to one entry per member sector. NAICS is a closed set, so a well-formed code absent from this snapshot is absent from the 2022 vintage. Refresh is a redeploy, never a live fetch.

## Output

Returns the verbatim Census Bureau title for the requested NAICS 2022 code, including its hierarchical level (2–6), and confirms whether the code exists in the 2022 vintage. Range-spelled sectors (31-33, 44-45, 48-49) are expanded to individual member sector entries.
