Douyin trend-index keyword trends API

Get the day-by-day search index and composite index of a keyword, or of one to five keywords at once, on Douyin over a date range, from 巨量算数 (the Douyin index), with the daily averages of the period, of the one before and of a year earlier. An index is the platform's score of volume, not a count of searches; days are calendar days in China time (UTC+8). About 1 item a call, 5 at most; $0.0060 per call. Errors and timeouts are not charged; an empty result is charged $0.0060.

Questions

How much does the Douyin trend-index keyword trends API cost?

$0.0060 per call. The most one call can cost is $0.0060.

When am I not charged?

Errors and timeouts are not charged; an empty result is charged $0.0060.

How many items does one call return, and how do I get the next page?

About 1 item a page, 5 at most. The page size is the platform's; limit is not accepted. Everything comes in one page; no cursor is issued.

What happens if the object does not exist?

A keyword the index does not cover is not in the answer; when none of the keywords asked for has figures the result is empty, never a not-found error. Asking only for days the platform has not published yet is an empty result too.

Where do the figures come from?

From 巨量算数 (Juliang Suanshu, also called the Douyin index), Douyin's own keyword index tool: the search index and the composite index it shows for the keyword, day by day. No Douyin or advertiser account is needed.

How often is it updated?

One figure per calendar day in China time (UTC+8). The platform publishes a day or two late: a day it has no figure for yet comes back with a null index.

How long a range can I ask for?

Any run of whole days from since to until, both included; one call costs the same whatever the range. The example asks for September 2026. Each keyword also comes with the daily averages of the period, of the period before and of the same period a year earlier.

How many keywords can one call take?

One with keyword, or one to five with keywords (a POST). The price is per call, $0.0060, so five keywords cost the same as one. A keyword the index does not cover is left out of the answer.

How do I use it in ChatGPT or Claude?

Connect DataXAPI once (one prompt with your key, on the agents page), then ask in plain words: "Get the Douyin index of 咖啡 for September 2026 with DataXAPI." The agent calls douyin.index.keywords.history and each call is charged $0.0060.

Parameters:
- keyword: One keyword, at most 50 characters and without a comma; letter case does not matter. Example: 咖啡.
