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.

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 |
