Lempile lets your product read LinkedIn profiles and inboxes, and send messages, invitations, posts and comments from your users' own accounts. It's Unipile-compatible (same paths, fields and errors), so switching takes two lines. Every account runs in its own session, on its own IP, at a human pace, and every write can be dry-run first. €49 a month for up to 10 accounts, no per-call fees, 7-day free trial with no card. X API in early access.
