SerpApi Java Library

Integrate search data into your Java application. This library is the official wrapper for SerpApi (https://serpapi.com).

SerpApi supports Google, Google Maps, Google Shopping, Baidu, Yandex, Yahoo, eBay, App Stores, and more.

The full documentation is available here.

Installation

Using Maven / Gradle.

Edit your build.gradle file

repositories {
    maven { url "https://jitpack.io" }
}

dependencies {
    implementation 'com.github.serpapi:serpapi-java:1.0.0'
}

To list all the version available. https://jitpack.io/api/builds/com.github.serpapi/serpapi-java

or you can download the jar file from https://github.com/serpapi/serpapi-java.git

Note: jitpack.io enables to download maven package directly from github release.

Usage

To get started with this project in Java. We provided a fully working example.

git clone https://github.com/serpapi/serpapi-java.git
cd serpapi-java/demo
make run api_key=<your private key>

Note: You need an account with SerpApi to obtain this key from: https://serpapi.com/dashboard

file: demo/src/main/java/demo/App.java

public class App {
    public static void main(String[] args) throws SerpApiException {
        if(args.length != 1) {
            System.out.println("Usage: app <secret api key>");
            System.exit(1);
        }

        String location = "Austin,Texas";
        System.out.println("find the first Coffee in " + location);

        // set api_key provided by the command line
        Map<String, String> auth = new HashMap<>();
        auth.put("api_key", args[0]);

        // Create search
        SerpApi serpapi= new SerpApi(auth);

        Map<String, String> parameter = new HashMap<>();
        parameter.put("q", "Coffee");
        parameter.put("location", location);

        try {
           // Perform search
           JsonObject data = serpapi.search(parameter);
           
           // Decode response
           JsonArray results = data.get("local_results").getAsJsonObject().get("places").getAsJsonArray();
           JsonObject first_result = results.get(0).getAsJsonObject();
           System.out.println("first coffee shop: " + first_result.get("title").getAsString() + " found on Google in " + location);
        } catch (SerpApiException e) {
            System.out.println("oops exception detected!");
            e.printStackTrace();
        }
    }
}

The SerpApi.com API Documentation contains a list of all the possible parameters that can be passed to the API.

Requirements

This project is an implementation of SerpApi in Java 7. This code depends on GSON for efficient JSON processing. The HTTP response are converted to JSON Object.

Runtime:

Java / JDK 8+ (https://www.java.com/en/download/) Older version of java do not support HTTPS protocol. The SSLv3 is buggy which leads to Java raising this exception: javax.net.ssl.SSLHandshakeException

For development:

Gradle 7.7+ (https://gradle.org/install/)

Location API

SerpApi serpapi = new SerpApi();

Map<String, String> parameter = new HashMap<String, String>();
parameter.put("q", "Austin");
parameter.put("limit", "3");
JsonArray location = serpapi.location(parameter);
assertEquals("Austin, TX", location.get(0).getAsJsonObject().get("name").getAsString());

it prints the first 3 location matching Austin (Texas, Texas, Rochester)

/src/test/java/serpapi/LocationApiTest.java

Search Archive API

Let's run a search to get a search_id.

Map<String, String> auth = new HashMap<>();
auth.put("api_key", System.getenv("API_KEY"));
SerpApi serpapi = new SerpApi(auth);

Map<String, String> parameter = new HashMap<>();
parameter.put("q", "Coffee");
parameter.put("location", "Austin, Texas, United States");
parameter.put("hl", "en");
parameter.put("gl", "us");
parameter.put("google_domain", "google.com");
parameter.put("safe", "active");
parameter.put("start", "10");
parameter.put("num", "10");
parameter.put("device", "desktop");
JsonObject results = serpapi.search(parameter);

Now let retrieve the previous search from the archive.

// now search in the archive
String id = results.getAsJsonObject("search_metadata").getAsJsonPrimitive("id").getAsString();

// retrieve search from the archive with speed for free
JsonObject archive = serpapi.searchArchive(id);
System.out.println(archive.toString());

it prints the search from the archive which matches 1:1 to previous search results.

/src/test/java/serpapi/SerpApiTest.java

Account API

Get account API

Map<String, String> parameter = new HashMap<>();
parameter.put("api_key", "your_api_key");

SerpApi serpapi = new SerpApi(parameter);
JsonObject account = serpapi.account();
System.out.println(account.toString());

it prints your account information.

We love true open source, continuous integration and Test Drive Development (TDD). We are using JUnit test, Git action, gradle our infrastructure around the clock to achieve the best QoS (Quality Of Service).

To run the test: gradle test

How to build from the source ?

You must clone this repository.

git clone https://github.com/serpapi/serpapi-java.git

Build the jar file.

gradle build

Copy the jar to your project lib/ directory.

cp build/libs/serpapi-java.jar path/to/yourproject/lib

Java limitation

SSL handshake error.

symptom

javax.net.ssl.SSLHandshakeException

cause

SerpApi is using HTTPS / SSLv3. Older JVM version do not support this protocol because it's more recent.

solution

Upgrade java to 1.8_201+ (which is recommended by Oracle).

On OSX you can switch versino of Java.

export JAVA_HOME=`/usr/libexec/java_home -v 1.8.0_201`
java -version

On Windows manually upgrade your JDK / JVM to the latest.
