Reviews are spread over shops and review videos, and the comments under a review often say more than the review. Reading enough of both to count what comes up is slow. ## What it uses The ready-made tool does the whole job in one request: SocialToAI runs the searches, reads the posts and comments, and returns one result with its sources. Each is priced before it runs. - [Comment analysis](https://socialtoai.com/tools/comment-insights.md): The topics in their comments and how big each is, plus questions, buying intent and complaints. From 38 credits a run. Your AI can also call the interfaces one at a time. These are the ones this job reads; each costs a fixed number of credits per call. | Platform | Interface | What it returns | Price key | Credits | | --- | --- | --- | --- | --- | | YouTube | [Comments](https://socialtoai.com/youtube-comments-api.md) | The comments under one video: text, likes and reply count. | `youtube.comments` | 2 | | YouTube | [Search](https://socialtoai.com/youtube-search-api.md) | Find videos by keyword: text, author and views. | `youtube.search` | 2 | | TikTok | [Shop product reviews](https://socialtoai.com/tiktok-product-reviews-api.md) | Get the first 10 buyers' reviews of a TikTok Shop product in the United States by the product's ID. | `tiktok.product_reviews` | 2 | | TikTok | [Shop product search](https://socialtoai.com/tiktok-product-search-api.md) | Search the products of TikTok Shop in the United States by terms. | `tiktok.product_search` | 2 | | Xiaohongshu | [Product reviews](https://socialtoai.com/xiaohongshu-product-reviews-api.md) | Get the first page of buyers' reviews of a product of Xiaohongshu's shop by the product's ID. | `xiaohongshu.product_reviews` | 12 | | Xiaohongshu | [Product search](https://socialtoai.com/xiaohongshu-product-search-api.md) | Search the products of Xiaohongshu's shop by terms. | `xiaohongshu.product_search` | 12 | ## A worked example A real run on the live service, recorded 2026-10-18: the question, the calls the AI chose and what it answered.
