Notes

Returns multiple NAICS codes ranked by confidence (0–1 scale). Most businesses match 1–3 codes.
The level field indicates code specificity: 2 = sector, 3 = subsector, 4 = industry group, 5 = industry, 6 = national industry.
Also returns a human-readable industries array alongside NAICS codes.
Classification results are cached and persisted to the brand record for future lookups.
Uses AI analysis of the website content — not self-reported data.
