Post Search
Searches public LinkedIn posts by keyword or phrase and returns ranked matches with author, text, engagement counts and post URLs, filterable by how recently they were posted. Public LinkedIn search covers posts only — member and job search are not available from any source, so this service does not claim them.
What you get
Each call returns up to 10 posts, plus a cursor for the next 10.
Endpoint
GET /v1/linkedin/post-search
Price
$1.50
per 1,000 calls · $0.0015 per call
Cost per call
1 credit
Failed calls never charged
Parameters
Keyword or phrase to search for in public LinkedIn posts.
Restrict results to posts published within this window.
One of: last-hour, last-day, last-week, last-month, last-year
Maximum records to return, capped at this service's page size (see Limits below). Omit it to receive the whole page. It shapes the response, not the price — a call costs the same either way.
Pagination cursor from a previous response. The highest cursor is `11`.
Bypass cached data and force a live fetch for this one call. Use it for daily monitoring or any figure you are tracking over time. Accepts `true`, `1`, `false` or `0`; anything else returns 400 `invalid_fresh`. Defaults to false and costs exactly the same as a cached call.
One of: true, 1, false, 0
Example request
Live call. Successful calls are charged; failed and empty results are not.

Each response includes a cursor. Pass it back as cursor to fetch the next 10 posts. Repeat until no cursor is returned.

- Maximum per call: 10 posts.
- Minimum per call: 1 post — a target with less data returns fewer posts, and an empty result is still a successful call.
- Each call fetches a full page of up to 10 and costs the same either way. Pass limit to receive fewer than that in the response.
- Larger jobs are paginated with a cursor; there is no cap on how many pages you fetch.
What this costs in practice
100,000 posts = 10,000 calls × 1 credits per call = 10,000 credits = $0.00
Priced at the Custom pack rate: 1,000,000 credits for $0.00.
