# NAICS 2022 Code Lookup

> NAICS 2022 Code Lookup is a paid API for AI agents from ccs-seller.bbrysonelite.workers.dev, paid per call via x402, $0.004/call, status unknown (last checked 2026-09-15).

Returns the official Census Bureau title and metadata for any NAICS 2022 code (levels 2–6) from a complete static snapshot of all 2,129 codes.

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-98c5674b
```

Example prompt: What is the official 2022 NAICS title for code 513210? I need the Census Bureau description for this industry classification.

## When to prefer this

Use this endpoint when you need an authoritative, offline-consistent lookup of any 2022 NAICS code title (levels 2–6) and want a deterministic response backed by a verifiable Census Bureau snapshot. Ideal for compliance workflows, data enrichment pipelines, or any context where you need to confirm whether a code is valid in the 2022 vintage. Because it is a static snapshot rather than a live fetch, responses are highly consistent and fast. Prefer this over web scraping or live Census APIs when reproducibility and low latency matter more than access to future vintages.

## Known failure modes

- NAICS code not found — code is well-formed but not present in 2022 vintage (valid negative result, not an error)
- Invalid code format — code does not conform to NAICS digit structure
- Payment failure — x402 payment of $0.004 USDC not completed
- Network/worker error — Cloudflare Workers infrastructure issue

## 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 code, along with source metadata including the 2022 vintage identifier, full coverage description, and a SHA-256 snapshot hash for data integrity verification. If the code is absent from the snapshot, it is definitively absent from the 2022 NAICS vintage.
