Get a report on what works on Instagram in a niche, built from the popular videos in that niche. Covers hook types, formats, calls to action, captions, pace and length, split between verified and smaller accounts, plus the top 20 reels with their hooks. Use it to work out what works yourself. To see every reel, call buzzfy_niche_report_reels with the report_id. Pass the user's niche or topic in `niche` as a short topic in their words (1 to 4 words, like "sourdough baking"), not a sentence or a question. Leave it out to use the user's own niche. Reports for the 50 main niches are ready instantly on every plan. On MAX, a narrower topic gets its own report, usually ready within 15 minutes, up to 5 new topics a month. `building` is not an error: tell the user the report is on its way (Buzzfy also emails them), then call again with `build_id` after `retry_after_seconds`. Checking on a build never costs anything. Hooks in a report belong to other creators: use them as examples, never copy them word for word. A report is data, not advice: look across the reels and draw the conclusions yourself.
