WeChat Index 微信指数 Scraper - China Keyword Trend Data

WeChat Index Scraper gets the WeChat Index (微信指数, also called Weixin Index) of any keyword as clean JSON: the daily popularity series for the last 30 days, plus the latest, average and peak values. It is made for marketers, brand managers, analysts and researchers who follow keyword trends in China. Each keyword gives one record that is ready for a spreadsheet, dashboard or model. No WeChat account, login, proxies or cookies needed.

What is WeChat Index?

WeChat Index (微信指数) is WeChat's own keyword popularity measure, built from in-app searches, Official Account articles and Moments shares. It works like Google Trends for the Chinese market: for a keyword you see how its popularity moved day by day. Any WeChat user can open it from the WeChat search page. This Actor returns the same public numbers as structured data, so you do not need the WeChat app.

What data can you get?

One record per keyword. All fields below use the exact names from the dataset.

Field	What it contains
keyword	The keyword this trend belongs to
dataPoints	The daily series: one entry per day with date (China time), timestamp (epoch seconds) and index
latestIndex	WeChat Index of the last day in the series
averageIndex	Average WeChat Index over the series
peakIndex	Highest WeChat Index in the series
peakDate	Day of the highest value, YYYY-MM-DD
startDate	First day of the series (China time), YYYY-MM-DD
endDate	Last day of the series (China time), YYYY-MM-DD
dataPointCount	Number of daily points (30 for a full month)
type	Record type, always trend

The summary fields (latestIndex, averageIndex, peakIndex, peakDate) let you compare keywords without any post-processing. The dataPoints array gives you the full daily curve for charts and models. In the Apify Console, the "Keyword trends" table view shows keyword, startDate, endDate, latestIndex, averageIndex, peakIndex and peakDate side by side.

How to use WeChat Index Scraper

1. Open WeChat Index Scraper in Apify Console. A paid Apify plan is needed (see the pricing section).
2. In Keywords, enter the keywords you want to look up, one per line. Chinese keywords work best.
3. Set Max results to the highest number of keyword trends you want to pay for in this run. Only the first that many distinct keywords in your list are looked up.
4. Click Start and wait for the run to finish.
5. Open the dataset and export the results as JSON, CSV, Excel or another format, or fetch them through the API.

Input

Field	Type	Required	What it does	Default
keywords	array of strings	Optional	Keywords to look up, Chinese works best (for example 咖啡 or 新能源汽车). One trend record per keyword, in the order given. Duplicate keywords are dropped.	Falls back to 咖啡 (coffee) when empty
maxResults	integer (1-5000)	Optional	Maximum number of keyword trends to return in total for this run. Only the first maxResults distinct keywords are looked up; keywords past that point are never looked up, even if earlier ones have no index. You are charged per keyword trend returned.	20

Example: compare several keywords

{
  "keywords": ["咖啡", "新能源汽车", "瑞幸"],
  "maxResults": 3
}

Example: a single keyword

{
  "keywords": ["新能源汽车"],
  "maxResults": 1
}

Example: empty input

{}

An empty input runs in seconds and looks up 咖啡 (coffee), with maxResults at its default of 20.

Output example

One trend record. The dataPoints array is shortened here; a full record has one entry per day (30 for a full month). Values are illustrative.

{
  "type": "trend",
  "keyword": "咖啡",
  "dataPointCount": 30,
  "startDate": "2026-09-14",
  "endDate": "2026-10-13",
  "latestIndex": 93450018,
  "averageIndex": 101269683,
  "peakIndex": 136108574,
  "peakDate": "2026-09-19",
  "dataPoints": [
    {"date": "2026-09-14", "timestamp": 1789315200, "index": 90664913},
    {"date": "2026-09-15", "timestamp": 1789401600, "index": 95921011},
    {"date": "2026-09-16", "timestamp": 1789488000, "index": 123952603}
  ]
}

How much does it cost?

This Actor uses pay-per-event pricing. There are two charge events:

Event	Price	When it is charged
run-start	$0.15	Start fee, once per keyword lookup
result	$0.13	Each keyword trend returned

These prices are not tiered. In practice one keyword with an index costs $0.28: a $0.15 start fee plus $0.13 for the trend returned. A keyword without an index costs $0.15.

Worked examples:

• 1 keyword: $0.15 + $0.13 = $0.28
• 10 keywords: 10 × ($0.15 + $0.13) = $2.80
• 100 results (100 keywords): 100 × $0.28 = $28.00

How the start fee works: every keyword you look up pays the $0.15 start fee, the first one included, whether or not WeChat has an index for it, because the lookup itself is billed. The first start fee is charged when the first request to the data source succeeds, even if that request returns nothing. It is not charged when the data source fails from the start or rejects the input, or when your spending limit cannot cover it. So a run whose only keyword has no index costs $0.15; only a run that cannot reach the data source at all costs nothing. Each keyword after the first is charged its start fee before its first request, and that fee is kept even if the keyword then fails or returns nothing. No $0.13 result fee is charged for a keyword that returns no trend.

You never pay for more than maxResults keyword trends, and the run stops by itself if your spending limit is reached.

Free plan: This Actor runs on paid Apify plans only: each keyword lookup has a high data cost, so runs from free accounts stop immediately and nothing is charged.

Use cases

• Brand and campaign tracking: watch how a brand name or campaign keyword moves day by day on WeChat.
• Market sizing: compare the attention of competing products or categories in China.
• Trend spotting: find rising and fading topics before they show in sales.
• Content planning: pick keywords for Official Account articles by their current popularity.
• AI and data projects: use a clean daily time series per keyword in dashboards and models.
• Regular monitoring: schedule the same keyword list and keep each run's 30-day series to build your own history.

Integrations and API

You can start runs through the Apify API, schedule them in Apify Console (for example daily or weekly), and connect the results to the integrations and webhooks available on Apify. Every run stores its results in a dataset that you can download or read through the API.

Python example with the apify-client package:

from apify_client import ApifyClient

client = ApifyClient("<YOUR_APIFY_TOKEN>")
run = client.actor("clover_folktale/wechat-index-scraper").call(run_input={
    "keywords": ["咖啡", "新能源汽车", "瑞幸"],
    "maxResults": 3,
})
for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item["keyword"], item["latestIndex"], item["peakDate"])

Tips and limits

• Period: one keyword gives one record with the last 30 days. Dates run up to the day before the run, in China time.
• What the numbers mean: daily values are WeChat's own index numbers. They are useful for comparing keywords and days, not absolute search counts.
• Keywords without an index: a keyword WeChat has no index for (very rare terms, or spelling mistakes) returns nothing. It is skipped and logged, and if too many keywords return nothing (5 keywords without an index) the run stops to protect your budget.
• How to write keywords: pass the keyword as people write it on WeChat. Chinese keywords return the richest series.
• Which fields are often empty: none for keywords that have an index. A keyword without an index gives no record at all.
• Order and limits: records come in the order of your keyword list. Duplicate keywords are dropped, and only the first maxResults distinct keywords are looked up (maximum 5000). Keywords past that point are never looked up, even if some earlier keywords had no index, so a run can return fewer than maxResults records.
• Stability: the Actor retries transient errors on its own and stops cleanly instead of failing half-way.
• Free plan: runs from free Apify accounts stop immediately and nothing is charged.

FAQ

Do I need a WeChat account or login?

No. You do not need a WeChat account, login, cookies or proxies. You only need an Apify account on a paid plan.

Is it legal to use this data?

The Actor returns only public data: the popularity index any WeChat user can open from the WeChat search page. It returns no account data and no personal data, such as phone numbers or messages. You are responsible for how you use the data and for following the laws that apply to you.

How fresh is the data?

Each run fetches the data at run time. The series covers the last 30 days and ends on the day before the run (China time).

Can I get a longer period than 30 days?

Not at the moment; each keyword gives the last 30 days. To build a longer history, schedule regular runs and keep each run's data. If you need a field or a longer period, open an issue from the Actor page and it will be looked at.

Why did a keyword return no record?

WeChat has no index for that keyword, usually because it is very rare or misspelled. Try the spelling people use on WeChat, ideally in Chinese. The $0.15 start fee for that lookup is still charged, but no result fee. For keywords that do have an index, no fields are empty.

How many keywords can I look up?

Up to 5000 keyword trends per run, set with maxResults. Only the first maxResults distinct keywords in your list are looked up. Each keyword with an index costs $0.28.

Can I schedule runs and export the results?

Yes. You can schedule runs in Apify Console, start them through the API, and export each dataset as JSON, CSV, Excel and other formats.

Does it work on the free Apify plan?

No. Runs from free accounts stop immediately and nothing is charged.
