One call costs 2 credits ($0.004 to $0.0067 depending on the pack); failed calls are free. Call it over HTTP or from your AI client over MCP. Last tested 2026-10-17.

nullFields LinkedIn cannot give

LinkedIn gives every field of this call. Where one item lacks a value, that field is null.

Every item also has platform, id, ref, approx and type; the response around the items is the same on every call. Response format

What to expect.

One call returns a page of up to 24 items. When page.has_more is true, send page.cursor back as cursor for the next page; each page costs 2 credits and a cursor works for 30 minutes.
A call that runs and finds nothing is a successful call: status is "empty", items is empty, and it costs 2 credits.

1 call per second per key, 5 after a purchase; going over is not charged. Rate limits

A failed call costs 0 credits and is never retried on its own. Error codes

Questions.
Short answers.

Everything on LinkedIn
Do I need a LinkedIn account or LinkedIn's own API access?
No. You only need a SocialToAI key. The call returns content and account information publicly visible on LinkedIn; you never sign in to LinkedIn or apply for anything there.
What does “Preview” mean here?
Preview: this interface is not marked stable yet, so its parameters and fields may still change. It is charged like any other call, and a failed call is not charged.
