trend_intelligence ($0.005/row) — adds rank velocity (points per day), saturation score (0-100), early-trend flag with confidence, related hashtags from cross-run co-occurrence, and rank history for every hashtag and creator row from region-based modes. Requires ≥2 prior runs of the same mode+region to produce a non-null rankVelocity. Uses a stateful key-value store keyed by rankHistory:<mode>:<region>:<identifier> and cooccur:<mode>:<region>. Triggered by enableTrendIntelligence=true.
industry_classification ($0.005/row) — classifies each hashtag or song into one of 20 industry categories (Beauty, Fashion, Food, Fitness, Gaming, Entertainment, Finance, Technology, Travel, Automotive, Education, Home, Pets, Parenting, Sports, Music, Art, Business, Healthcare, Lifestyle) via a short LLM call. Uses the buyer's own Anthropic or OpenAI API key passed via aiEnrichmentApiKey. If no key is set, the event is silently skipped and nothing is charged. Max 30 output tokens per call. Triggered by enableIndustryClassification=true.
ai_brand_brief ($0.015/row) — generates a 2-3 sentence actionable brief per hashtag or song: what the trend is, which brand category fits, one example campaign angle. Uses the buyer's LLM key. Max 300 output tokens per call. Skipped silently (no charge) when the key is missing. Triggered by enableAiBrief=true.
region_summary_report ($0.05/report) — emits one aggregated row (rowType: 'region_summary') at the end of each region-based mode run (trending_feed, popular_hashtags, popular_creators). Includes totals, top-10 hashtags/sounds/creators, dominant industries (when classification is also on), and run-level averages for rank velocity, new-entry count, and saturation index. Triggered by enableRegionSummary=true.
