The essentials

  • Google Search API for AI agents and applications
  • Pay as you go, ~$0.001/request
  • Google results in JSON: organic, images, news, shopping, maps
  • Built for engineers building AI agents that need real-time web access

What is Serper?

Serper is an API that gives you access to Google Search results in JSON. The primary use case: giving a LLM or AI agent the ability to search the web in real time. Instead of using the official Google Custom Search API (limited and expensive), Serper is a cheaper, simpler alternative. Results include organic SERPs, Knowledge Cards, images, news, and shopping depending on what you need.

Strengths

Competitive pricing

At around $0.001 per request, Serper is significantly cheaper than the Google Custom Search API. For applications with high search volume, the gap is substantial.

Simple integration

Serper's REST API is straightforward. One POST request with your API key and query, JSON in return. Integration takes minutes in any project.

Used in major AI frameworks

Serper is natively integrated in LangChain, LlamaIndex and other frameworks. Ecosystem compatibility is excellent.

Limits

Google dependency

Serper scrapes Google results. If Google changes its structure or blocks the service, it's impacted. Long-term stability is less guaranteed than an official API.

For specialized search needs (academic research, specific databases), Serper is limited to generic Google results.

Pricing

Pay as you go. A free plan with 2,500 requests/month is available. Check serper.dev for plans and included volume.

Alternatives

For official Google results: Google Custom Search API. For native AI search: Tavily. For advanced web scraping: Exa.

Verdict

Serper is the reference for integrating Google Search into AI agents. The price is unbeatable, integration is simple. For AI search use cases, it's often the first pick.

FAQ

Serper works by scraping Google. Commercial use may be in a gray area with Google's ToS. Check the terms on serper.dev.

Does Serper support searches in languages other than English?

Yes, you can specify country and language in the API request to get localized results.

What's the latency of the Serper API?

Latency is generally under 1 second for organic results. Check benchmarks on serper.dev.

Does Serper work with LangChain?

Yes, Serper is an official tool in LangChain. Integration is direct with the SerperAPIWrapper class.
