Linkup
Web search API from Paris for AI agents and LLM apps, with fast and deep search, page fetch, and research endpoints priced per call.
AI product teams that need accurate, cited web results at low cost per call, including European companies with data residency needs.
Teams that need a large people or company index, or buyers who want a long list of enterprise references.
Verdict
Linkup is a web search company in Paris, France, started in 2024 by Philippe Mizrahi, Denis Charrier, and Boris Toledano, with teams in New York and San Francisco. AI companies such as Legora and Artisan use its API to search the web, fetch pages, and run longer research tasks so their agents answer from current, cited sources. It stands out for pairing low per-call prices with strong accuracy scores and per-jurisdiction endpoints for data residency, which matters for legal and finance products in Europe.

Review Excerpts
Below are excerpts from public reviews. Our team scoured public reviews, forums, and chat rooms to get a balanced view of customers' experience with this company. Paid reviews and pay-for-play sites such as Clutch were excluded.
“Linkup is what makes self-serve onboarding work at our speed. Customer enrichment used to be the longest step. Now it happens before the customer notices, and Ava is sending within minutes.”
“As soon as you query the web, it's really better than LLM providers’ native solutions. It's better, more reliable and drastically less expensive.”
“Deep search is ten times the price of standard search, five cents a call against half a cent, and our agent kept picking deep when it didn't need to. We ended up hard-coding when it's allowed.”
