Serper

Fast, low-cost Google Search API designed for developers and AI agents. Returns structured Google SERP data (organic results, knowledge graph, related searches) via a simple REST API. Positioned as the cheapest way to give agents Google-quality search results, $0.001/query at scale. Widely used in LangChain and agent frameworks as a cost-effective alternative to Tavily for high-volume use cases.

Serper.dev Google Search API, verified live June 2026. Proprietary closed search API (web/images/news/maps/shopping/video/scholar). Sub-segment: search APIs (Tavily/Exa peer, closed counterpart).

commercial key-gated Google Search API, JSON output, 2,500 free queries then paid; no OSS license

Adoption

not assessed

Popular low-cost SERP API widely wired into agent stacks (LangChain/CrewAI tool integrations), but vendor publishes no hard user/query-volume figure and no primary download/API-call count is verifiable. Declining to score adoption rather than rely on marketing 'fastest & cheapest' claims.

no published user/query-volume figures, only marketing speed/price claims

Capability

3 medium confidence

3.0

Broad search-type coverage with structured output and live freshness; solid feature matrix for a search API, but thinner than full agent-search tools (no built-in extraction/answer synthesis like Tavily/Exa). Rated 3 on coverage/freshness/structured-output dimensions.
