## When to prefer this

Use this endpoint when you have a NAICS code and need to resolve it to a human-readable industry title — particularly in B2B onboarding, regulatory filings, market research tagging, or corporate data enrichment workflows. It is pay-per-call with no API key required, making it ideal for low-volume or on-demand agent tasks. Prefer this over a static lookup table when you need data-vintage assurance and confidence scoring.

## Known failure modes

- Invalid or non-existent NAICS code returns supported:false
- 4-digit or 7-digit codes outside the accepted 5–6 digit range may fail validation
- Ambiguous or partially matched codes may return a lower confidence score
- Payment failure via x402/USDC will block the request before processing
- Network timeouts on the Cloudflare Workers edge in rare cases

## How this service works

Resolves North American Industry Classification System (NAICS) industry titles.

## Output

Returns a JSON object with the matched NAICS code, its official industry title (e.g. 'Software Publishers'), a supported flag, a confidence level ('high'/'medium'/'low'), the data vintage date, and any warnings or disclaimers about informational use only.
