Linkup

Linkup is a state-of-the-art AI search API, engineered to ground AI applications in factual, verifiable data. It serves as a powerful bridge between your AI systems and the vast, dynamic information on the web, delivering structured, sourced answers to eliminate hallucinations and enhance reliability. Trusted by developers and companies worldwide, Linkup provides the critical data infrastructure for building intelligent, fact-based applications, from AI agents and chatbots to deep research and business intelligence tools.

The platform is built on the principle that AI should be based on hard facts. It achieves this by integrating with authoritative data sources and employing a superior search engine that ranks #1 on OpenAI’s SimpleQA factuality benchmark. Linkup offers two distinct search modes to cater to different needs: a blazing-fast standard search for real-time applications and a comprehensive deep search for complex, nuanced queries.

How to use Linkup

Integrating Linkup into your workflow is designed to be a seamless and rapid process. Here’s a typical workflow:

1. Get Your API Key: Sign up on the Linkup website to receive your unique API key. A free plan is available to get started immediately without a credit card.
2. Choose Your Integration Method: Linkup can be integrated directly via its REST API using simple code snippets for Python, Node.js, or cURL. For example, in Python, you would initialize the client and call the `search` method with your query.
3. Use Pre-built Integrations: For even faster setup, Linkup is natively supported by major AI orchestration platforms like CrewAI, Langchain, Make, n8n, and Zapier. This allows for no-code or low-code integration into existing agentic workflows.
4. Select Your Search Type: Depending on your needs, you can specify the search depth. Use `Standard` for quick, factual answers (e.g., for a chatbot) or `Deep` for in-depth analysis (e.g., for a market research report).
5. Process the Response: The API returns a structured JSON object containing the direct answer and a list of sources, complete with URLs and snippets, allowing for full traceability and verification.
