Fast, cheap Google Search API for AI agents — sub-2s responses at pennies per thousand queries.
Fast, cheap Google Search API for AI agents — sub-2s responses at pennies per thousand queries.
Serper is a developer-focused Google Search API positioned as the fastest and cheapest way for an AI agent to reach live search results without scraping. It returns organic results, People Also Ask, knowledge graphs, images, videos, news, shopping, scholar, and places — all as clean JSON — with typical latencies under two seconds. Because search is the default first tool for any research agent, deep-research pipeline, or RAG-plus-web assistant, Serper has become one of the most commonly wired tools in LangChain, LlamaIndex, CrewAI, and MCP server ecosystems. Pricing is aggressive: 2,500 free credits on signup, then $50 for 50,000 queries on the Starter plan and volume discounts down to $0.30 per thousand at the Ultimate tier. There's a Chrome extension, a Google Maps endpoint, autocomplete, and image reverse-search endpoints, so the same API can back a location-aware agent, a shopping copilot, or an image similarity flow. Serper is a smaller shop than SerpAPI but competes on speed and price, and community MCP servers wrap it so any MCP client can add live web search in a few config lines.
Serper is a low-cost Google SERP API for AI agents, with fast response times, structured JSON output, and a credit model that starts at 2,500 free queries and $50 for 50,000 paid queries. It does one thing well: turning Google results into API-ready data for applications that already have their own orchestration, ranking, or page-reading layer.
Serper converts Google search results into JSON that applications can consume directly. It supports organic results, knowledge graphs, answer boxes, People Also Ask sections, related searches, and shopping-oriented result data, reducing the need for fragile HTML parsing.
Serper advertises typical response times of about 1-2 seconds for a search request. That makes it practical for user-facing AI agents where long search latency would noticeably slow the final answer.
Serper supports more than standard web search, including images, news, maps, places, videos, shopping, scholar, patents, and autocomplete. This gives agents and applications more context when the task involves local businesses, visual discovery, product research, recent events, academic references, or patent lookup.
Serper is commonly used in LangChain, LlamaIndex, and CrewAI ecosystems. In those workflows, Serper acts as the search tool while the framework handles planning, tool selection, memory, and multi-step execution.
Serper lists 2,500 free queries and paid credit packs starting at $50 for 50,000 credits, with larger packs lowering the per-1,000-query price. For teams that trigger many searches from AI agents, that pricing can keep retrieval costs predictable.

We believe in transparent reviews. Here's what Serper doesn't handle well:
As of the 2026 review, Serper continues to emphasize low-cost Google SERP access for AI retrieval workflows, broad Google result-type coverage, API-key authentication, and credit-based pricing. Teams should verify current pricing, rate limits, search modes, and security documentation directly on Serper before production deployment.
