What does Linkupapi do?
Linkupapi is an API that connects AI agents to B2B channels like LinkedIn, WhatsApp, and real-time web data. Instead of building separate integrations for each platform, developers can use a single API to send messages, search people and companies, monitor signals, and access email data. The tool is designed for teams that want to automate outreach, lead generation, and sales workflows without managing multiple APIs.
The API offers several dedicated modules: Engagement API for sending LinkedIn messages, Person API for searching profiles, Company API for company enrichment, Signal API for real-time event monitoring (like new posts or role changes), and Email API for finding email addresses. Each endpoint is exposed via RESTful calls with a simple payload structure, as shown in the code examples on the homepage. Linkupapi promises fast response times (under 3 seconds on average), over 50 endpoints, and 99.9% uptime.
Linkupapi is best suited for developers building AI-powered sales assistants, marketing automation tools, or custom B2B data pipelines. Sales teams can use it to automate personalized LinkedIn outreach, while marketers can track signals to identify hot leads. The API also works well for startups and agencies that need a single integration point for multiple B2B channels without the overhead of connecting each platform individually.
