Linkup

Linkup provides a web search API for AI systems. Its three endpoints are Fetch, which retrieves content from a web page, Search, which returns sourced answers with full-text snippets, and Research, which runs asynchronous in-depth research. The website lists integrations with the OpenAI SDK, LangChain and CrewAI.

The website names frontier AI labs, global financial institutions, Fortune 500 companies and government agencies among its customers. Pricing is pay-as-you-go per request with a free tier of 4,000 queries, plus an Enterprise plan with custom pricing, private indexes, SOC 2 Type II and ZDR availability.

Enterprise options include a Private Index and a Bring Your Own Cloud deployment. The careers page lists open roles in GTM, HR, and engineering and research, with locations in New York, San Francisco and Paris. The site does not state a founding year or funding.
