Strengths & caveats
Parallel Web SystemsLargest free tier in this table (5000 requests/month) and a cheap low-latency path: Turbo and Fast are $1/1k, with Basic and Advanced at $5/1k, all returning token-efficient excerpts built for agents. Its relevance score cannot be used here: the independent eval scored tiers named Base (13.50) and Pro (14.21, ~13.6s average latency) that no longer match Parallel's current Turbo/Fast/Basic/Advanced tiers, so no score maps to a priced tier.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.
