Google's first party Custom Search JSON API still exists in 2026 but remains capped and stripped down, pushing serious builders to third party SERP providers. The question is which provider gives you real time SERPs, rich features like AI Overviews and People Also Ask, and a price that does not balloon with volume. We scored the top four Google Search APIs on freshness, coverage of SERP widgets, latency, and how cleanly their JSON fits into an LLM tool call. The best Google Search API in 2026 is the one you can drop into production without rewriting response parsers six months later.
Scavio wins on price, breadth of SERP features, and agent ergonomics. Full AI Overview, People Also Ask, Knowledge Graph, and organic results come back in a single normalized payload, and thirty dollars a month covers seven thousand searches.
