Production-grade web search API for grounded AI answers and full-text snippets
What is Linkup?
Linkup is a production-grade web search API for AI applications. It is designed to return grounded, sourced answers from the web with full-text snippets, and the site positions it as infrastructure for teams building search into agents, copilots, and other production systems.
The product can be used through a one-line API call or deployed inside a customer-owned cloud environment. The site also describes options for private indexes and configurable freshness, sources, and retrieval behavior, which makes the service fit both general web search and more controlled enterprise workflows.
What can Linkup do?
Multiple query modes
Choose between Fetch, Search, and Research modes, each aimed at a different workload such as page extraction, agent tool calls, or asynchronous deep research.
Configurable retrieval
Tune the search experience by selecting the index, sources, and freshness so the retrieval layer matches a specific domain or workflow.
Private deployment options
Deploy with options for a private index or bring-your-own-cloud setup when data control and environment constraints matter.
Developer-friendly integrations
Use the product with example code and SDK support shown for Python, Node.js, cURL, the OpenAI SDK wrapper, LangChain, and CrewAI.
Usage-based pricing
Purchase on a transparent pay-as-you-go model, with a free query allowance and enterprise pricing for custom environments and support.
Use Cases
“Agent web search”
Build AI agents that need live web lookups instead of static training data, using search results that include citations and snippets.
“Research assistants”
Create research copilots or internal assistants that gather current information and return grounded answers for complex questions.
“Legal research”
Support legal AI workflows that depend on up-to-date web data, as highlighted by the legal AI case study and customer story collection.
“Sales and investment intelligence”
Power sales, deal sourcing, and CRM enrichment workflows that pull recent signals from the web and structured pages.
“Enterprise deployment”
Run enterprise search workflows in controlled environments where teams want private indexing or cloud-bound deployment.
