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.

Feature-by-feature comparison
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.
Consider Scavio instead
Scavio is the generalist layer underneath. Cover Google SERP, Reddit, YouTube transcripts, Amazon, and Walmart from one key, then reach for Linkup or Sonar only when a specific workflow demands premium sources or prebuilt synthesis.
