Create classification rule

Create a custom classification rule. Matching entities in /follows/enriched, /classify, and /discover automatically get your custom sector, entity type, tags, and priority applied. Conditions support bio_keywords (any match), username_pattern (regex, max 100 chars, no nested quantifiers), sector_contains, and must_be_company. Free, costs 0 credits. Limit 100 rules per account (500 on Enterprise).
