What does Linkup do?
Linkup is a production-grade web search API built for AI applications. Instead of scraping or stitching together multiple search services, developers make a single API call and get sourced, cited answers with full-text snippets from across the web. The API is designed to be fast, accurate, and grounded in real data from trusted sources — no hallucinations, no black boxes.
What sets Linkup apart is the level of control it gives developers. You can tune the search index, pick which sources to include, and set how fresh the results need to be. The API supports multiple deployment modes: use it as a public API, or run the full indexing layer inside your own cloud for compliance and data sovereignty. It integrates with popular AI frameworks like LangChain, CrewAI, and the OpenAI SDK, so dropping it into an existing stack takes one line of code. Linkup also offers sub-second latency, 99.9% uptime backed by an SLA, and flexible pricing.
Linkup is built for teams shipping AI in production — legal AI platforms, research copilots, sales agents, and voice assistants all need search tuned to their domain. It's already trusted by Fortune 500 companies, frontier AI labs, and government agencies. If you're building an AI system that needs reliable, real-time access to web data, Linkup gives you the infrastructure without the headache.
