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.

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.
