Product / UX / Agent tools & protocols

Serper

Google Search API for developers and agents, returning structured search-results-page data including organic results, the knowledge graph and related searches over a simple REST interface. It is positioned on price and latency for high-volume use.

The vendor publishes price and latency copy but no user, customer or query-volume figure, and there is no package to count, so adoption abstains rather than banding on marketing claims. Verified 2026-08-13 via serper.dev.

license: proprietary(API-only)

Key-gated hosted Google Search API returning structured JSON. "Get 2,500 free queries"; pricing "starting at $0.30 per 1,000 queries". No license, repository link, self-host or on-premise option.

Adoption

not assessed

Popular low-cost SERP API widely wired into agent stacks (LangChain/CrewAI tool integrations), but the vendor publishes no hard user or query-volume figure and no primary download or API-call count is verifiable. serper.dev carries price and speed copy only - "The World's Fastest and Cheapest Google Search API", "search results in 1-2 seconds, at an unbeatable price starting at $0.30 per 1,000 queries" - and a rate card is not a volume. There is no package, repository or registry artifact to band either. Declining to score adoption rather than rely on marketing 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.

https://serper.dev recorded 2026-08-13
Vertical tabs including Scholar and Patents with worked structured-JSON responses; "search results in 1-2 seconds". No extraction, crawl or answer-synthesis endpoint offered.
