Strengths & caveats
Perplexity AIRaw Search API is a flat $5/1k for clean web results, and Sonar adds synthesized, citation-backed answers in one call — convenient for answer-style agents. Pricing is hard to compare (raw Search is $5/1k, but Sonar adds per-token charges plus a $5-$14/1k request fee by context size); ranked last-but-one on relevance (12.96) and the synthesized path measured ~11s latency in the independent eval.SerpApiGives true Google/Bing SERP data (ads, rich snippets, knowledge panels) parsed into structured JSON — the closest to 'what a human sees on Google'. Subscription-based ($25/1k entry, dropping to ~$5/1k only at high reserved volume) so not directly comparable per-query; ranked last on the independent agent relevance eval (12.28) and returns raw SERP fields, not LLM-ground-ready content.
