Linkup is a web search API for AI applications. It offers three endpoints: Fetch retrieves information from a web page, Search returns sub-second sourced results, and Research gives in-depth results for complex questions. Search returns cited answers with full-text snippets.
Developers call the API from Python, Node.js or cURL, or through wrappers for the OpenAI SDK and agent frameworks. Results come back with sources so that an application can ground its answers.
Developers building AI agents and applications that need current web information. The vendor lists SOC 2 Type II, HIPAA, SSO and zero data retention, and a 99.9% uptime SLA.
Linkup links to a pricing page and does not list plans or prices on its main page.
