LinkedIn Search API

Q: How do I get only the latest posts on a topic?

Set date_range to past_1_hour, past_24_hours, past_week or past_month, and sort to newest; no_filter applies no time window. The window applies to when posts were published, not to job validity or anyone's employment dates. Parse posted_at defensively, since non-standard time strings are passed through as is.

Q: How do I read the comments on a post I found?

Pass the post's link from url to the LinkedIn Comments capability, which takes a full post link and returns the comments under it. comment_count tells you beforehand how many comments a post has, so you can skip posts that drew no discussion.

Find LinkedIn posts that match a keyword. Get author, text, reactions and engagement counts. You can limit by posting date and sort by newest or relevance. Private posts, messages and reach analytics are out of scope.

Send POST https://api.everyinfra.com/api/v1/social with platform set to linkedin and action set to search. Price $3.19 per 1,000 requests ($0.003194 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.

LinkedIn Search finds public LinkedIn posts by keyword and returns each post's text, author name and username, like and comment counts, link and publish time. It shows who is talking about a topic on LinkedIn and how much engagement the conversation draws. B2B marketers and PR teams use it for social listening and tracking mentions of a brand or product, and sales teams use it to find people who post about a problem they solve.

Narrow results by publish time with date_range, from the past hour to the past month, and choose newest or relevance in sort. It searches posts only; people are found with LinkedIn Profile search and job postings with LinkedIn Jobs. A null like_count or comment_count means the number was not disclosed, not that it is zero, and author_username can usually be used to build the author's LinkedIn link.

AI prompt

Please help me write a data collection script with the EveryInfra LinkedIn Search endpoint (linkedin/search).

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 search, and put the parameters inside params.
- Required parameters:
  - keyword: Specifies the search string, acting as a post search keyword in search, a current job title in profile_search, or a job search term or full job URL in jobs.
- Optional parameters:
  - date_range: Filters post publishing timestamps for the search action using allowed values no_filter, past_1_hour, past_24_hours, past_week, or past_month. (allowed: no_filter / past_1_hour / past_24_hours / past_month / past_week)
  - sort: Sets the sorting order to newest or relevance for post search and comment fetching. Because these actions target different object types, this parameter does not sort people, companies, or job listings. (allowed: newest / relevance)
  - 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 return 422 before any charge. (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": "search",
  "params": {
    "keyword": "data engineer"
  }
}
- Price: $3.19 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).

FAQ

Can this search people or jobs?

No, it searches posts. For people, use LinkedIn Profile search, which looks people up by current job title; for job postings, use LinkedIn Jobs, which takes a job search term or a LinkedIn job search URL. Each capability returns its own kind of record, so pick the one that matches what you want to count.

How do I get only the latest posts on a topic?

Set date_range to past_1_hour, past_24_hours, past_week or past_month, and sort to newest; no_filter applies no time window. The window applies to when posts were published, not to job validity or anyone's employment dates. Parse posted_at defensively, since non-standard time strings are passed through as is.

How do I read the comments on a post I found?

Pass the post's link from url to the LinkedIn Comments capability, which takes a full post link and returns the comments under it. comment_count tells you beforehand how many comments a post has, so you can skip posts that drew no discussion.
