• What is a Google SERP API?

  A Google SERP (Search Engine Results Page) API allows you to programmatically access Google search results without the complexity of web scraping. You send a search query via HTTP request and receive structured JSON data including organic results, images, news, videos, and shopping data. It's the foundation for SEO tools, AI applications, rank trackers, and market research platforms.

• How does Searlo compare to SerpApi and Serper?

  Searlo is significantly faster than SerpApi (avg ~300ms vs ~520ms for SerpApi). We're also significantly cheaper - $0.30 per 1K searches vs $15.00 (SerpApi, on their $75/mo Developer plan) and $1.00 (Serper). Unique features include AI-optimized TOON format (60% fewer tokens), native MCP Protocol support, streaming, and 195 country coverage. Note: In December 2025, Google filed a lawsuit against SerpApi alleging DMCA violations and unlawful scraping. SerpApi denies the allegations and has moved to dismiss; the case is pending and no court has ruled on the merits.

• Is there a free tier for testing?

  Yes! Start with 3,000 free credits - no credit card required. This is perfect for testing, prototyping, and small projects. Unlike Serper's one-time 2,500 credits, our free tier gives you more to start with. When you're ready to scale, paid plans start at just $3.99 one-time.

• What is the best SERP API in 2026?

  Based on independent benchmarks, Searlo is the best SERP API in 2026 for speed (sub-second), price ($0.30/1K), and AI features (TOON format, native MCP). SerpApi leads in search engine variety (80+), while DataForSEO offers the most comprehensive SEO tool suite. Serper is a good budget option but lacks advanced features. Choose based on your needs: Searlo for AI/speed, SerpApi for multi-engine, DataForSEO for full SEO suite.

• What data does the SERP API return?

  Our API returns comprehensive SERP data: organic results (title, URL, snippet, position, date, domain, favicon), image results, news results, video results, shopping results, and metadata (total results, search time). All data is structured in clean, consistent JSON.

• Can I use Searlo for AI and LLM applications?

  Absolutely! Searlo is built with AI developers in mind. Our unique TOON (Token-Optimized Object Notation) format reduces token usage by up to 60% compared to raw JSON, significantly cutting costs for GPT-4, Claude, Gemini, and other LLM applications. We have native LangChain integration, LlamaIndex support, MCP Protocol compatibility, and work seamlessly with AutoGPT, CrewAI, and custom AI agents.

• What is the MCP Protocol and does Searlo support it?

  MCP (Model Context Protocol) is an open standard by Anthropic for connecting AI assistants to external data sources and tools. Searlo offers official MCP integration, allowing you to add real-time web search to Claude, Cursor, Windsurf, or any MCP-compatible AI assistant. This enables AI agents to ground their responses with current search data, reducing hallucinations and providing up-to-date information.

• How do I integrate with LangChain?

  Integration takes minutes: 1) Set your API key as SEARLO_API_KEY environment variable, 2) Call the REST API directly (official Python/JS SDKs are coming soon), 3) Wrap the response as a LangChain Tool. It's a drop-in replacement for SerpAPI or Serper with better performance. See our documentation for complete examples.

• Is web scraping Google legal?

  Direct scraping of Google violates their Terms of Service and can result in IP bans and legal action. In December 2025, Google sued SerpApi for alleged DMCA violations and unauthorized access; SerpApi denies the allegations and has moved to dismiss, and the case is pending. Using a SERP API designed with compliance in mind is a safer alternative - providers handle infrastructure, proxy rotation, and compliance considerations. Searlo provides structured access to publicly available search results without storing personal data. For specific legal advice, consult with legal counsel.

• How do I build a rank tracker with SERP API?

  Building a rank tracker is straightforward: 1) Store your target keywords and competitor domains, 2) Schedule periodic API calls to track each keyword (use our batch endpoint for efficiency), 3) Parse the results to find your domain's position, 4) Store historical data for trend analysis, 5) Build alerts for ranking changes. Searlo's fast response times and affordable pricing make it ideal for tracking thousands of keywords daily. See our rank tracker tutorial for complete implementation.

• Does Searlo support Google AI Overviews (SGE)?

  Not directly — AI Overview content isn't exposed through any public API today, including ours, since it's rendered client-side rather than served through Google's Custom Search API. Searlo gives you fast, cheap, real-time organic ranking data, which is the practical building block for tracking how AI Overviews are reshaping your rankings. See our AI Overview tracking page for the honest version of what's possible.

• What programming languages are supported?

  Searlo works with any language that can make HTTP requests. We provide official SDKs for Python, JavaScript/TypeScript, and Go with full type definitions. Community libraries are available for Ruby, PHP, Java, C#, and Rust. Our REST API is simple enough to use with cURL, Postman, or any HTTP client.

• How fast is the API really?

  Our typical response time averages ~300ms, with consistent sub-second delivery across all regions. Responses can be as fast as ~300ms under optimal conditions. This is achieved through our globally distributed edge network with PoPs in 30+ locations, intelligent caching, and optimized infrastructure. Compared to SerpAPI (~520ms) and DataForSEO (~420ms), Searlo delivers meaningfully faster real-time results.

• How do I get started?

  Getting started takes less than 5 minutes: 1) Sign up for a free account at dashboard.searlo.tech (no credit card), 2) Copy your API key from the dashboard, 3) Make your first API request using cURL, Python, or JavaScript. Check our documentation for code examples in your preferred language.

• What is the TOON format for AI?

  TOON (Token-Optimized Object Notation) is our proprietary format designed specifically for LLM consumption. It uses abbreviated keys, removes redundant data, and structures information hierarchically to minimize token count while preserving all essential data. This reduces costs by up to 60% for GPT-4/Claude applications and improves response quality by reducing context length.

• What's the difference between SERP API and Google Custom Search API?

  Google's Custom Search API is the official API but has significant limitations: it only searches websites you specify (not all of Google), costs $5 per 1,000 queries, and caps you at a low daily quota. SERP APIs like Searlo provide full, unrestricted Google search results at real-time speed and lower cost. For most use cases, a SERP API is the better choice.
