## Overview

LinkupAPI is an outreach and B2B data API built for AI agents and software products. A single key and request format covers the whole loop: find prospects with people search and company data, spot intent from LinkedIn reactions, reach them on LinkedIn, email, WhatsApp or iMessage, and receive every reply through one webhook. Alongside outreach it provides a Prospect Data API (profiles, company data, job postings, funding rounds as JSON), a Mail API for finding, verifying and enriching professional email addresses, and an Engagement API for building messaging features into your product. An MCP server lets agents in Claude or Cursor run the same workflows, and integrations include n8n, Make and Zapier.
