What is Linkup?
Linkup is a Web Search API for AI applications, and its official website positions itself as "The Web Search API for AI". Unlike directly returning search results to end users, it encapsulates web search capabilities into an API for AI applications, agents and enterprises to call in their own systems, outputting answers based on real sources with citations and full-text fragments. The official website states that it is used in production environments by some AI labs and financial institutions, and performs leading on benchmarks such as OpenAI's SimpleQA.
Who is it for?
- Teams building AI applications and agents that require real-time web connectivity and traceable sources for answers, with a strong emphasis on citeability.
- Development and data teams building enterprise-grade retrieval and research assistants that require stable retrieval quality and metrics.
- Engineers who need to integrate web data into their own knowledge bases or RAG workflows, replacing fragile manual crawling.
- Financial institutions and large enterprises with compliance requirements for data residency and private deployment can use the BYOC solution.
Key features
6Search
Provides web search capabilities for AI applications, returning answers with source citations and full-text snippets. The results are based on credible sources rather than being generated out of thin air.
Research
Provides in-depth research results for complex questions, rather than simple snippet-based answers, making it suitable for due diligence and long-chain reasoning.
Fetch
Crawls information from specified web pages, returns results in sub-second time with leading accuracy, making it easy to incorporate web pages into context.
Private Indexing
Customize indexes, select data sources, and set data freshness to control the scope and specifications of retrieval.
Bring Your Own Cloud
Supports deployment to the user's own cloud environment, meets data and compliance requirements, and avoids data outbound.
One-line Code Integration
Official SDKs and examples for Python, Node.js, cURL, etc., are provided to facilitate integration with existing pipelines.
