Show the text
Use the DataXAPI endpoint wechat.index.keywords.history (WeChat Index). Get a keyword's WeChat Index over the last 30 days, one figure a day. The WeChat Index is WeChat's score of attention across its search, articles, Moments and more, not a count of searches, and is not comparable with Douyin's or Xiaohongshu's; days are calendar days in China time (UTC+8).
Call GET https://api.dataxapi.com/v1/wechat/index/keywords/history with the header "Authorization: Bearer $DATAXAPI_API_KEY". Read the key from the environment variable DATAXAPI_API_KEY; never write it into code.
Parameters:
- keyword (required): One keyword. Example: 咖啡.
- view: How much of each item to return. All three cost the same. Values: compact, standard (default), full.
- fields: Return only these fields. Each by its path, such as author.name.
Price: $0.1 per call. Errors and timeouts are not charged; an empty result is charged $0.1.

  --data-urlencode "keyword=咖啡" \
  -H "Authorization: Bearer $DATAXAPI_API_KEY"
