Social listening tools count what people said. This API scores whether a phrase is rising on a named source. POST https://api.trendsapi.ai/api with source tiktok, reddit, or youtube. Hootsuite's 2026 listening roundup still treats Brandwatch as a historical conversation archive (quote-based) and Sprout as a management suite with listening as a module. Neither product is a 0-100 demand series. Phrase rules for short-form sit on the TikTok guide. HTTP fields sit on the API reference. Mention tools return posts. This response hides those posts inside a string body that still needs a second decode.
