## The question

> What are people asking in the comments under trending coffee videos on Douyin?

Questions and buying signals are scattered among jokes and emoji in the comments, and Douyin shows them a few at a time.

## What the AI did

It chose the tools itself: 1 request on Douyin. Each row is one tool call as the client showed it, with what it sent, how much came back and what it cost.

| Platform | Tool | Sent | Requests | Returned | Credits |
| --- | --- | --- | --- | --- | --- |
| Douyin | [`comment_insights`](https://socialtoai.com/tools/comment-insights.md) | `targets: ["https://www.douyin.com/video/7696845789318456571","https://www.douyin.com/video/7697458024826604785"] · scale: "small"` | 1 | 36 comments | 50 |
| **Total** |  |  | 1 | 36 items | **50** |

## The answer

What the client answered, from what it had read. The line under each finding is a post it read, or a figure from those posts.

Recorded 2026-10-18

I read 36 comments under 2 videos; of the 28 that could be judged, 11 ask a question and 7 want to buy. The topics:

1. **How to buy it** (25%, 7 comments): [“小程序怎么买啊”](https://www.douyin.com/video/7696845789318456571)
2. **Mistaking it for rice** (21%, 6 comments): [“我开始以为白花花的是大米呢”](https://www.douyin.com/video/7696845789318456571)
3. **Favourite coffee drinks** (18%, 5 comments): [“我最喜欢摩卡”](https://www.douyin.com/video/7697458024826604785)

Used 50 credits · $0.17. Every claim links to its source.

### The posts it rests on

A selection of what was read; the marked words are what a finding rests on. An item without a link says so.

## What it cost

1 request, 50 credits in total: $0.17 at the $10 rate. Every answer of the API states the credits it charged and the balance left, so your AI can tell you what a question cost. A call that fails costs nothing.

| Pack | Credits per dollar | This answer |
| --- | --- | --- |
| $10 = 3,000 credits | 300 | $0.17 |
| $50 = 20,000 credits | 400 | $0.13 |
| $200 = 100,000 credits | 500 | $0.1 |

## Ask it yourself

Connect SocialToAI to your AI client once ([the steps for each client](https://socialtoai.com/mcp.md)), then paste the question. You do not name tools or parameters: the client picks them.

**Prompt**

```
What are people asking in the comments under trending coffee videos on Douyin?
```

The same in code: the calls this run made, as requests to the API.

**tool.comment_insights**

```
curl https://api.socialtoai.com/v1/tools/comment_insights \
  -H "Authorization: Bearer $SOCIALTOAI_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "targets": ["https://www.douyin.com/video/7696845789318456571","https://www.douyin.com/video/7697458024826604785"],
    "scale": "small"
  }'
```
