TikTok trend scraper with Gemini video analysis

A webhook starts it and reads your settings record from Airtable: a comma-separated list of topics, how many videos to fetch per topic, and the analysis prompt.

For each topic, an Apify actor finds this week's TikToks, sorts them and keeps the top ones, then upserts them into Airtable with views, likes, comments, caption and hashtags. Each video that has not been analyzed yet is downloaded, uploaded to Gemini and analyzed. The category, style, tone, hook, visual hook, CTA and analysis are written back to its record.
