Linkup is an AI-powered search API designed specifically for developers building AI applications, chatbots, and intelligent systems. Unlike general-purpose search engines or chatbots, Linkup was built from the ground up to provide accurate, reliable web information that AI agents and language models can use to ground their responses in factual data.

How Does Linkup Work?

You integrate Linkup's API into your AI project using a simple API key. When your AI application needs information, it sends a query to Linkup, which searches trusted web sources and returns facts instantly in a clear, structured format complete with sources. This allows your AI to answer questions, conduct research, and enrich applications with verified information.

What Are the Different Search Options?

Linkup offers two search depths tailored to different needs. Standard provides fast and affordable web search, ideal for quickly finding straightforward information that improves AI accuracy, with example queries like 'What is Microsoft's Q3 2024 revenue?' Standard queries cost 5 euros per 1,000 queries. Deep offers comprehensive, in-depth web search for complex queries requiring multiple steps of information gathering and reflection, with example queries like 'What are the differences in strategy between Apple and Samsung for 2025?' Deep queries cost 50 euros per 1,000 queries.

How Does Linkup Compare to Perplexity Sonar?

While Perplexity is a generalist chatbot designed for human users, Linkup was specifically designed to be the most accurate search engine for AI systems. Linkup scores higher on OpenAI's factuality benchmark SimpleQA. Additionally, Linkup has partnerships with trusted data providers and premium information sources to ensure critical business decisions can be based on accurate answers. Linkup also focuses on the needs of AI agents and technology systems, providing raw context or structured outputs rather than only natural language answers.

Is Linkup Compliant with Privacy Regulations?

Yes, Linkup is fully compliant with GDPR and CCPA. The platform uses a zero-storage architecture that processes data on-the-fly without permanent storage, eliminating potential security vulnerabilities. All data processing occurs exclusively within the EU, ensuring compliance with EU data residency requirements.

What is Linkup's Data Retention Policy?

Standard data retention is 3 years after last interaction for business continuity. Upon contract termination or written request, all customer data is securely purged within 30 days from primary storage and 90 days from backups. Custom retention periods, including immediate deletion options, can be established based on client requirements.

What AI Models Does Linkup Use?

Linkup leverages a range of state-of-the-art AI models across its technology stack, continuously optimizing for accuracy, speed, and relevance. The platform has developed a proprietary model designed specifically for high-precision retrieval and business intelligence to power its search capabilities.

Can I Use Linkup with Different LLM Providers?

Yes, Linkup is designed to work with AI models from various providers like OpenAI, Mistral, and others. The platform is model-agnostic and can integrate with any LLM that your application supports.

What Support Options Are Available?

All paid plans include email support with response times under 24 hours. Premium and Enterprise plans receive priority support with dedicated account managers and direct WhatsApp access.

Is the Linkup Search MCP Server Free?

The MCP server itself is an open-source component, though the underlying Linkup API operates on a paid plan structure based on usage.
