Linkup vs Perplexity Sonar

Linkup and Perplexity Sonar both claim the 'AI research API' slot but get there from different directions. Linkup bets on licensed premium sources -- Le Monde, Statista, and similar -- as the ground truth. Sonar bets on LLM-wrapped synthesis over web results. Picking between them is really a question about whether source provenance or answer quality matters more for your use case.

The verdict

Linkup wins when provenance is the product -- regulated industries, citation-heavy research, EU data residency. Sonar wins when polished answers are the product and the $50 floor is fine. For most agent builders, neither is the cheap default -- both are specialists you add when the generalist layer isn't enough.
