Linkup

Linkup is a web search API built for AI applications, addressing the need for accurate, timely, and grounded data in models whose knowledge is fixed after training. It provides sourced, cited answers with full-text snippets from across the web, and can be integrated through a single API call or deployed inside a customer's own cloud infrastructure.

The service offers three product modes: Fetch for URL content extraction, Search for web search with sub-second results, and Research for asynchronous deep research on complex questions. Search settings allow control over the index, sources, and freshness. It integrates with the OpenAI SDK wrapper, LangChain, CrewAI, and other frameworks, and supports deployment modes including a private index and bring-your-own-cloud. Enterprise features include custom indexes, user management, dedicated dashboards, single sign-on, zero data retention, and SOC 2 Type II compliance.

Linkup is aimed at developers and AI teams building agents, RAG pipelines, and other LLM-powered applications, as well as enterprise AI teams. Pricing is pay-as-you-go and usage-based, with per-request rates that vary by mode and tier. A free allocation of queries is available, and an Enterprise plan offers custom pricing, a private environment, and dedicated support.
