Pull the posts for a hashtag, a keyword or a sound, read their views, likes, shares and saves, and see which creators and formats lead. Then read the comments, and check TikTok Shop for the products behind the trend.

- TikTok: from $0.00045 per record
- History: Free
- Free to start: $0.10

## The workflow

1. Run TikTok searchPosts with exactly one of query, hashtag or soundUrl: views, likes, comments, shares, saves, sound, hashtags and duration per post.
2. Rank the posts by views and saves, and note the sounds and hashtags that repeat.
3. Run TikTok profiles on the creators behind the top posts for followers, total likes and video count.
4. Run TikTok comments on up to ten top posts to read how people react.
5. Run TikTok shop with the product keyword for price, discount, rating, sold count, seller and stock per variant.
6. Read TikTok history for free to see follower growth from past captures.

## Operations used

List prices per record. A call can carry a minimum, so quote first: the quote is free, and a record that does not come back is not charged.

| Step | Operation | What comes back | Price |
|---|---|---|---|
| 1 | TikTok searchPosts | Posts by keyword, hashtag or sound, with engagement | $0.0018 per record |
| 2 | TikTok profiles | Followers, following, total likes, video count, bio | $0.0022 per record |
| 3 | TikTok comments | Top-level comments on up to ten posts | $0.00045 per record |
| 4 | TikTok shop | Price, discount, rating, sold count, seller, variant stock | $0.013 per record |

> **Quote first** A searchPosts call can return up to 100 posts. Send it with "estimateOnly": true to see the most it can cost, and set "maxUsd" when you run it for a list of hashtags.

## Questions

### Can I search by sound?

Yes. Pass a TikTok sound page URL (tiktok.com/music/...) as soundUrl and get the posts made with that sound.

### Can I combine a keyword and a hashtag?

No. Send exactly one of query, hashtag or soundUrl per call, and run two calls to compare.

### Does it return view counts?

Yes. Every post carries views, likes, comments, shares and saves.

## Why API for Agents

- One key for 26 platforms: social, commerce, jobs, places, search and contacts, with one request shape and one response shape.
- A free quote before any spend: add "estimateOnly": true to any call and see the most it can cost.
- Pay per record in US dollars. No subscription, nothing expires, top-ups from $5.
- $0.10 free to try, no card. An AI agent can sign itself up in one request; a person claims it later.
- Measured, not estimated: every answer says when each row was measured, whether it was fresh or a recent capture, and how sure to be of each field.
- Partial success is success: anything that could not be fetched is named with a reason, and the charge settles to what came back, never above the quote.
- Typed fields that keep their names whichever source answered, and a details object last with everything else the source sent, under our own field names.
- Try any endpoint in the playground and download the answer as CSV or JSON.

## Start

The playground runs any endpoint by hand: pick a platform and what you want from it, fill a short form named in plain words (or press Use sample input), see the free quote on the Run button, run it, then read the answer as a table or JSON and download it as CSV or JSON. The same call is written out as cURL, Python and Node while you type. Open it at https://apiforagents.dev/dashboard/run (sign in first).
