Send a connection request from your connected account, with an optional note (300 characters). Already connected or already invited comes back as a miss, never as a duplicate send.

Unit: per_invitation · unmatched results billed: no
Priced per request sent. LinkedIn allows roughly 100 a day and 200 a week per account; refusals bill nothing.
The exact quote is returned by /v1/inspect before every call and held with headroom (1.5x the quote) on execution. The quote is the price floor: if the provider's actual cost overruns it, the run bills at about 1.5x cost, never above the hold. The unused part of every hold is released.
