# How do I get data out of Douyin's trend index (巨量算数)?

Two ways. On [its website](https://trendinsight.oceanengine.com/) you read one keyword or brand at a time, which suits a look. To pull many, or let your AI read them, call the 10 interfaces here, from 2 credits a call (about $0.0067), with no login: keyword index and audience, brand against its industry, creators, hot topics. Each answers JSON.

## Which way suits what

|  | Its website | The interfaces here |
| --- | --- | --- |
| Suits | A look at one keyword | Many keywords, a weekly sheet, your AI's answer |
| What you need | A browser | A SocialToAI key, or sign-in from your AI client |
| What comes back | Charts on a page | JSON, one call an interface |
| Cost | See its site | From 2 credits a call; failed calls are free |

Every interface, by keyword, brand, creator and topic, is on [the Douyin trend index API page](https://socialtoai.com/douyin-trend-index-api.md).

## FAQ

### Is it the same as the Douyin index?

People use both names for it: 巨量算数 is the tool, and its index is what is often called the Douyin index.

### Do I need a 巨量算数 account?

Not through the interfaces. You need one SocialToAI key, or sign-in from your AI client.
