Do I need a LinkedIn developer account?

No. There is no LinkedIn app, OAuth flow or app review. One InsightSocial API key works for this endpoint and every other platform, and your first 10 calls priced at 100 credits or less are free.

How do I get every result, not just the first page?

This endpoint pages. Each response carries pagination.next_cursor and pagination.has_more. Send next_cursor back unchanged as the cursor parameter and stop when has_more is false. Every page is a separate call and is charged as one.

What happens if the account is private or nothing is found?

You get an error or an empty result, and it costs 0 credits. The API reads public LinkedIn data only, so private accounts and deleted content come back as not found rather than as partial data.

Can I call the LinkedIn Profile Posts Archive API from Claude, ChatGPT or Cursor?

Yes. Add the hosted MCP server at https://api.insightsocial.app/mcp to your AI app and sign in. The assistant finds this endpoint by name, shows its price and calls it with your credits.

When to use it

It is metered per post returned, so ask for the limit you need.

Parameters

Query parameters for GET /v1/linkedin/profile/posts/archive. Send your key in the x-api-key header.

Name	Required	Description
url	Yes	The member's LinkedIn profile URL, for example https://www.linkedin.com/in/williamhgates/.
limit	No	How many posts to return, 1 to 100 (default 20). Pass 100 to walk the full archive: only a full page returns a next_cursor.
cursor	No	The pagination.next_cursor from the previous page, sent back unchanged. Omit it for the first page.

Response fields

The same unified schema every platform returns, so code written for LinkedIn works on the other eight. A field the platform did not provide is null and listed in unavailable.

Every field, error and example is in the LinkedIn Profile Posts Archive API reference.

How much does the LinkedIn Profile Posts Archive API cost?

Metered: 50–5,000 credits a call. The ceiling is reserved when the call starts and you are charged what it actually read.

Failed calls are free
A call that errors or finds nothing costs 0 credits.
Know the price first
Add dry_run=1 and the response quotes the call without making it. Nothing is charged.
One balance
API calls and Chrome extension exports share the same credits, on the free plan too.
