Content research means finding what topics have demand, what questions people ask, what competitors publish, and what gaps exist. The best search API for content research must cover multiple platforms (Google for SERP landscape, Reddit for community questions, YouTube for video content gaps), return rich data per query, and price affordably since research involves many exploratory searches.
Scavio wins for content research because it provides Google SERP data, Reddit discussions, and YouTube content landscape under one API. A research session of 50 searches across three platforms costs $0.25.
