LinkedIn API

What can you do with the Search Hashtag API?

The Search Hashtag endpoint gives you structured LinkedIn data with computed fields in a single request. No scraping infrastructure to build or maintain.

Example Request

# GET /v1/linkedin/search/hashtag: 10 credits per call. Cache hits are free and failed calls are refunded.
# Check the price first for 0 credits: add dry_run=1 to the query. Nothing is fetched or charged.
# --max-time 10: this endpoint's measured p99 latency x 1.5.
# --retry 3: retries timeouts, 429 and 5xx, honoring Retry-After.
# -o response.json keeps only the final attempt's body.
# One Idempotency-Key per request, reused on every retry, so a retried call is never charged twice.

Parameters

ParameterRequiredDescription
queryYesHashtag to search, with or without a leading #.
sort_byNoResult ordering: recent, oldest, or relevance. (recent | oldest | relevance)
sinceNoOnly rows published on or after this date: YYYY-MM-DD (midnight UTC) or an ISO 8601 timestamp. Rows older than it are left off each page. This list is not in date order, so the walk does not stop at the date: keep following `next_cursor`, and each page costs what a page costs even when every row on it is filtered out. A row with no date is kept. `published_after`, `start_date`, `from_date`, `publish_time` (`yesterday`, `this-week`, `this-month`, `last-3-months`, `last-6-months`) and `max_age_days` are accepted and applied as `since`.
untilNoOnly rows published on or before this date: YYYY-MM-DD (that whole UTC day is included) or an ISO 8601 timestamp. Newer rows are left off each page and the walk does not stop, so older pages follow. A row with no date is kept. `published_before`, `end_date` and `to_date` are accepted and applied as `until`.
Example Response

What does the LinkedIn Search Hashtag API return?
Returns public LinkedIn posts tagged with a hashtag, each with text, author, engagement, and date. The response uses the same JSON envelope as every SocialCrawl endpoint, with the data, credits_used and request_id fields.
When should I use the LinkedIn Search Hashtag endpoint?
Use it to monitor a tag. Keyword search across posts is search/posts.
How much does the LinkedIn Search Hashtag API cost?
Each call costs 10 credits, so the 100 free credits every new account gets cover 10 calls. Credits for failed or empty calls are refunded automatically, and there is no subscription.

The one required parameter is query (hashtag to search, with or without a leading #). It also accepts 3 optional parameters, all listed on this page.
