Use GET /web/naics when your system requires 2022 North American Industry Classification System codes. The endpoint accepts a domain or company title and returns one or more code candidates.

Classify a company

The endpoint costs 10 credits.

Read the candidates

Keep code as a string. Store name, confidence, and the resolved domain with it so a future reviewer can understand what was classified.

Control result count

Result count is not a confidence threshold. If your workflow should accept only strong matches, filter the returned candidates by confidence and allow an empty result after filtering.

Production behavior

  • Prefer a domain over a company name when both are available.
  • Do not treat a model-selected code as proof of an official registration.
  • Keep the taxonomy version in your data model if records must remain auditable over time.
  • Treat 404 as a normal no-match and 408 or 429 as retryable with a bounded policy.
The API returns code candidates, not a copy of the full taxonomy.
