Follow what one LinkedIn member has been posting, from the /in/ username or profile link in username. Each post has text, posting time, reactions by type, like, comment and share counts and a reshare flag; an article card appears only when the post links one. Newest first, 10 by default, up to 50.

Price $4 per 1,000 requests ($0.004 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.

Please help me write a data collection script with the EveryInfra LinkedIn Person posts endpoint (linkedin/person_posts).

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 linkedin and action to person_posts, and put the parameters inside params.
- Required parameters:
  - username: The member's /in/ username or full profile link, such as williamhgates. A display name with spaces is not recognised.
- Optional parameters:
  - limit: The most rows to return in this call, an integer from 1 to 50. The default applies when you leave it out, and a call can return fewer rows. Larger values are accepted and capped at the maximum. (default: 10)
- Returns a list of records. Main fields of each record: id, url, text, author_name, author_username, author_headline, author_id (Numeric member ID of the post author (s…), author_url (Profile link of the post author (search…), author_avatar_url (Avatar link of the post author (search)), author_type, reactions (Reaction counts by type (search): each…), attachment (Card attached to the post (search): typ…); 18 fields in total, full list at https://api.everyinfra.com/api/v1/social/catalog?platform=linkedin.
- Example request body:
{
  "platform": "linkedin",
  "action": "person_posts",
  "params": {
    "username": "williamhgates"
  }
}
- Price: $4 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
`id`	The record's unique ID on the platform. Unique only within one platform; IDs can repeat across platforms.
`url`	Link to the record on the platform.
`text`	Body text with HTML removed, returned in full and never cut short (on a few platforms the list results themselves carry only an excerpt; the platform's field notes say so).
`author_name`	Author's display name.
`author_username`	Author's username (@handle), usually usable in URLs.
`author_headline`	Keeps the platform's own meaning
`author_id`	Numeric member ID of the post author (search).
`author_url`	Profile link of the post author (search), without tracking parameters.
`author_avatar_url`	Avatar link of the post author (search).
`author_type`	Keeps the platform's own meaning
`reactions`	Reaction counts by type (search): each entry has type (like, appreciation, empathy and so on) and count.
`attachment`	Card attached to the post (search): type (for example job or article), title, description, subtitle, url and image_url.
`like_count`	Likes. null means the platform or this capability does not disclose it; it is not 0.
`comment_count`	Comments. null means not disclosed, not 0.
`share_count`	Number of times the post was reshared.
`hashtags`	Hashtag list of the company page or post.
`is_reshare`	Whether the post is a reshare of another post.
`posted_at`	Publish time in ISO 8601, UTC (for example 2026-08-07T12:34:56+00:00). Non-standard strings from the platform are passed through as is, so parse defensively. null means the platform does not disclose it.
`platform`	Source platform identifier, the same as platform in the request (for example xiaohongshu, tiktok).
