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
# the same limits as every pack.Step 02 / 03
One GET request with the query, the country and the language. Web search answers in about 1 second at the median, 2.5 seconds at p90.
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.

The three organic results for “postgres connection pooling” — as a results page shows them, and as Searlo returns them. Same call, 2026-09-04.

For an environment without an application server, PostgreSQL provides two implementations of DataSource which an application can use directly.

Connection pooling in PostgreSQL refers to the creation and management of a pool of pre-established database connections.

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 · 34 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) returns a search engine's results page as structured data. 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 returns web search results in about 1 second at the median (p90 about 2.5 seconds, measured September 2026), structured for AI and SEO workflows.
Google's Custom Search JSON API is closed to new customers, and existing customers' "Search the entire web" option ends on 1 January 2027. Searlo returns live Google results pages as JSON — organic listings, images, news and shopping — 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: $0.30/1K pricing on one-time credit packs, 3,000 free credits to start, 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 focuses on Google results 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.
Yes. Searlo gives 3,000 free credits once, on sign-up — no credit card required. They are a one-time grant, not a monthly allowance; for comparison, SerpAPI offers 250/month free searches and Serper 2,500 one-time credits. The free credits work on every search type, including web, images, news and shopping, with the same rate limits as a paid pack. New users: 1-year 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. Web search answers in about 1 second at the median (p90 about 2.5 seconds), 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.
Yes. The full-SERP endpoint, GET /serp, returns Google's AI Overview, its text and cited sources, at 3 credits per page, alongside ads, People Also Ask and related searches. From November 1, 2026, a page whose AI Overview has to be completed by rendering the page costs 8 credits, and the response says aioverview.rendered: true. The AI Overview is included by default on /serp; set aioverview=false to skip it and stay at 3. For the answers ChatGPT, Microsoft Copilot and Gemini give, and the sources they cite, see the AI visibility API.
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 affordable pricing and batch endpoint make it suitable for tracking thousands of keywords. See our rank tracker tutorial for a complete implementation.
Every plan, including the free credits, gets the same limits: there is no tier to climb, and buying more credits adds credits, not rate. Every response carries X-RateLimit-* headers with your current limits. The limits guard the service; they are not a capacity promise. For sustained high volume, such as a large nightly batch, tell us your volume first and we will reserve capacity for it.
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.
