Track a Douyin creator's follower count over time as a dated series, with the average follower count across the window. Pass the creator's secUid in user_id. The series alone does not show what caused any growth.

Send POST https://api.everyinfra.com/api/v1/social with platform set to douyin and action set to creator_trend. Price $0.56 per 1,000 requests ($0.000556 per call). Failed calls and empty results are not charged. Synchronous. For slow jobs add "mode": "async" to the body, take the job_id and poll.

AI prompt

Please help me write a data collection script with the EveryInfra Douyin Creator growth trend endpoint (douyin/creator_trend).

How the endpoint works:
- Request: POST https://api.everyinfra.com/api/v1/social with the header Authorization: Bearer <API key>. Read the key from the EVERYINFRA_API_KEY environment variable and never hard-code it.
- In the request body, set platform to douyin and action to creator_trend, and put the parameters inside params.
- Required parameters:
- user_id: The Douyin creator's secUid, usually beginning with MS4w, used to read the available follower-trend series. It is not a nickname or short numerical Douyin ID.
- Returns one object. Main fields: user_id, follower_trend, average_follower_count, dimension_code.
- Example request body:
{
"platform": "douyin",
"action": "creator_trend",
"params": {
"user_id": "https://www.douyin.com/user/MS4wLjABAAAAk1tZ-L085zZf2yW_H5dnVFZWyk8Rt8v4RAvf9KhTyPoVdMDxTs7Q_rvgTJGWXezS"
}
}
- Price: $0.56 per 1,000 requests; failed and empty results are not charged.
- For dozens or hundreds of targets, add "mode": "async" to the body: you get a job_id at once and poll GET https://api.everyinfra.com/api/v1/jobs/{job_id} for the result.
- On 422, fix the request using the suggested parameter names and allowed values in the error; on 429 or 503, wait for Retry-After and try again.

Before writing code, ask me which targets I need, how many, which fields, and what output format I want; then confirm the plan and the rough cost with me.

Response fields

Business data is in results. The table lists the fields a record can contain; values the platform does not show are never made up.

Field	Meaning
`user_id`	User's unique ID on the platform.
`follower_trend`	Keeps the platform's own meaning
`average_follower_count`	Keeps the platform's own meaning
`dimension_code`	Keeps the platform's own meaning
`platform`	Source platform identifier, the same as platform in the request (for example xiaohongshu, tiktok).
