Three steps, and the third one is the whole product.
Step 01 / 03
Sign up and copy the key from the dashboard. 3,000 free credits come with the account, and nothing asks for a card.
# One header. That is the whole of authentication.
x-api-key: sk_live_••••••••••••••••••••
# A new account starts with 3,000 credits and
# 5 requests a second. The tier rises with credits bought.Step 02 / 03
One GET request. No browser to drive, no proxy pool to rent, no CAPTCHA to solve.
curl "https://api.searlo.tech/api/v1/search/web?q=postgres+connection+pooling&num=3" \
-H "x-api-key: $SEARLO_KEY"
# Add &format=toon for a response a language model reads
# in 63% fewer tokens (per the format reference).Step 03 / 03
Organic results with position, title, link, domain and snippet — as JSON, or as TOON when the reader is a language model.

Improve database performance with connection pooling
Connection poolers such as pgbouncer and pgpool-II can be used to pool connections from clients to a PostgreSQL database.

Replayed
Captured against production on 2026-09-04 and replayed here. The request, the status row and the response are the capture — trimmed only of favicon, thumbnail and link fields the frame has no room for.
Flow 01 / 03
GET /search/web · format=toonAdd format=toon and the response comes back as text a language model reads in fewer tokens — a header line, then one block per result. This is that text, exactly as it returned.
The web search for “postgres connection pooling” with format=toon returns a header line with the result count, then a numbered block per result with its title, link, snippet, site and domain.
Flow 02 / 03
GET /search/mapsOne GET to /search/maps. Name, category, rating, review count, price band, address and whether it is open right now — the first three places, as returned.
The maps search for “coffee shops in Austin” returns 3 places, each with position, title, category, rating, review count, price, address and open state, for 1 credit.
Flow 03 / 03
MCPPoint any MCP client at the server with your key in the header, and these are the tools it is handed — searches, balance, usage and keys — with no SDK between them.
An MCP client configured with the server URL and the API key header is handed 8 tools: web_search, maps_search, check_balance, get_usage_stats, get_search_history, get_search_stats, get_transaction_history, list_api_keys.
Endpoints · 17 in the published spec
Web, images, news, video, shopping, local businesses and the account endpoints that tell you what a key can do.

Agents need fresh facts, a cheap token bill and a tool they can call without a wrapper. That is three decisions, and they are all here.
Point Claude, Cursor or any Model Context Protocol client at the server and the assistant can search the live web itself. Setup is one config block. MCP setup.

}The same organic results in a shape a model reads more cheaply — abbreviated keys, no repeated field names. The figure is the one in the format reference in the docs.

FAQ
A SERP API (Search Engine Results Page API) allows you to programmatically access Google search results without managing browsers, proxies, or CAPTCHA solving. You send an HTTP request with a search query, and receive structured JSON data containing organic results, images, news, and shopping data. Searlo's API delivers this data with sub-second response times, structured for AI and SEO workflows.
Not for full search results. Google retired its Web Search API, and the Custom Search JSON API is limited to a configured set of sites, capped at 10,000 queries/day, and costs about $5.00 per 1,000 queries beyond a small free quota — so it isn't a true Google SERP API. To get complete, real-time Google search results (organic listings, images, news, and shopping data), developers use a dedicated SERP API like Searlo, starting at $0.30 per 1,000 queries with 3,000 free credits.
It depends on your priorities. Searlo stands out on price and AI-readiness: sub-second response times, $0.30/1K pricing, and AI features like TOON format and native MCP Protocol. SerpAPI has the broadest engine support (80+), while DataForSEO offers the most comprehensive SEO toolkit. Choose based on your needs: Searlo for price and AI, SerpAPI for multi-engine, DataForSEO for a full SEO suite.
Searlo delivers sub-second responses with a focus on Google and AI workflows. The biggest difference is price: Searlo charges $0.30/1K queries against SerpAPI's $15.00/1K and Serper's $1.00/1K. Searlo also offers features those two lack: AI-optimised TOON output and native MCP Protocol for AI agents. SerpAPI supports 80+ search engines; Searlo focuses on Google with the lowest price and AI-native output.
Direct scraping of Google violates their Terms of Service and can result in legal action — in December 2025, Google sued SerpAPI for alleged DMCA violations; SerpAPI has moved to dismiss and the case is pending. Using a SERP API is a safer approach: providers like Searlo handle infrastructure, proxy rotation, and compliance considerations. Searlo provides structured access to publicly available search results and is designed with compliance in mind. For specific legal advice regarding your use case, consult with legal counsel.
Yes. Searlo offers 3,000 free credits on sign-up — no credit card required. That is more generous than the alternatives: SerpAPI offers 250/month free searches, and Serper's 2,500 credits are one-time only. The free tier includes full access to all search types including web, images, news, and shopping. New users: 90-day validity. Legacy users: unlimited credits.
TOON (Token-Optimized Object Notation) is Searlo's output format for LLMs. It uses abbreviated keys, removes redundant data, and structures information hierarchically to minimise token count — about 63% fewer tokens than the raw JSON response, per the format reference in our docs. That means lower model costs and more room for context in your prompts.
Yes. Searlo has LangChain and LlamaIndex integrations, plus MCP (Model Context Protocol) support for connecting to Claude, Cursor, and other AI assistants. Sub-second latency matters for real-time agents, and the TOON format is optimised for token efficiency. Use Searlo to ground your LLMs with real-time web data and reduce hallucinations. See our tutorials for integration examples.
Not directly — AI Overview content isn't exposed through any public API, including ours, since it's rendered client-side rather than served through Google's Custom Search API. What Searlo gives you is 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 guide for the honest version of what's actually possible today.
Searlo works with any language that can make HTTP requests. Our REST API is simple enough to use with cURL, Postman, or any HTTP client, and the docs carry copy-paste examples for cURL, Python and Node.js.
Building a rank tracker is straightforward: 1) Store your target keywords and domains in a database, 2) Schedule periodic API calls for each keyword using our batch endpoint, 3) Parse results to find your domain's position, 4) Store historical data for trend analysis, 5) Build alerts for significant ranking changes. Searlo's fast response times and affordable pricing make it suitable for tracking thousands of keywords. See our rank tracker tutorial for a complete implementation.
Rate limits scale automatically with your tier: Free (5 req/s), Micro (10 req/s), Starter (10 req/s), Builder (20 req/s), Scale (30 req/s), Pro (50 req/s), Enterprise (300 req/s). Your tier upgrades automatically as you purchase more credits — no plan changes needed. Every response carries rate-limit headers so you can track usage in real time.
Getting started takes under five minutes: 1) Sign up for a free account at dashboard.searlo.tech (no credit card required), 2) Copy your API key from the dashboard, 3) Make your first API request using cURL, Python, or JavaScript. The documentation includes quickstart guides, code examples for all major languages, and an interactive API playground.
