SerpApi Go Library

Integrate search data into your Go application. This library is the official wrapper for SerpApi.

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

Installation

Go 1.10 is required.

go get -u github.com/serpapi/serpapi-golang

Simple Usage

import "github.com/serpapi/serpapi-golang"
setting := serpapi.NewSerpApiClientSetting("<SERPAPI_KEY>") // Replace with your SerpApi key
setting.Engine = "google" // Set the search engine to Google
client := serpapi.NewClient(setting)
parameter := map[string]string{
  "q":             "Coffee",
  "location":      "Austin, Texas, United States",
}
results, err := client.Search(parameter)
fmt.Println(results)

This example runs a search for "coffee" on Google. It then returns the results a Go Hash. See the playground to generate your own code.

Advanced Usage

Search API

func main() {
  // Initialize the client with custom setting
	setting := serpapi.NewSerpApiClientSetting("<SERPAPI_KEY>") // Replace with your SerpApi key
	setting.Persistent = false                     // Enable persistent search
	setting.Asynchronous = true                    // Enable asynchronous search
	setting.Timeout = 60 * time.Second             // Set timeout for HTTP requests
	setting.MaxIdleConnection = 10                 // Set maximum idle connections
	setting.KeepAlive = 60 * time.Second           // Set keep-alive duration
	setting.TLSHandshakeTimeout = 10 * time.Second // Set TLS handshake timeout

	client := serpapi.NewClient(setting)

  // search query overview (more fields available depending on search engine)
  parameter := map[string]string{
    "q":             "Coffee",
    "location":      "Austin, Texas, United States",
    "hl":            "en",
    "gl":            "us",
    "google_domain": "google.com",
    "safe":          "active",
    "start":         "10",
    "num":           "10",
    "device":        "desktop",
  }

  // formated search results as a Hash
  // serpapi.com converts HTML -> JSON
  rsp, err := client.Search(parameter)

  if err != nil {
    panic(err)
  }
  fmt.Println(rsp)

  // raw search engine html as a String
  // serpapi.com acts a proxy to provive high throughputs, no search limit and more.
  raw_html, err := client.Html(parameter)
  if err != nil { 
    panic(err)
  }
  fmt.Println(raw_html)
}

Location API

import (
	"fmt"
	"github.com/serpapi/serpapi-golang"
)

setting := serpapi.NewSerpApiClientSetting("<SERPAPI_KEY>") // Replace with your SerpApi secret key
client := serpapi.NewClient(setting)
locationList, err := client.Location("Austin", 5)

if err != nil {
  panic(err)
}
fmt.Println(locationList)

It prints the first 5 locations matching Austin (Texas, Texas, Rochester)

[map[canonical_name:Austin,TX,Texas,United States country_code:US google_id:200635 google_parent_id:21176 gps:[-97.7430608 30.267153]...

Search Archive API

This API allows retrieving previous search results. To fetch earlier results from the search_id.

First, you need to run a search and save the search id.

// First, you need to run a search and save the search id.
auth := map[string]string{
  "engine":  "google",
  "api_key": "secret_api_key",
}
client := serpapi.NewClient(auth)
parameter := map[string]string{
  "q":        "Coffee",
  "location": "Portland"}

rsp, err := client.Search(parameter)

if err != nil {
  t.Error("unexpected error", err)
  return
}

// Now let's retrieve the previous search results from the archive.
searchID := rsp["search_metadata"].(map[string]interface{})["id"].(string)
if len(searchID) == 0 {
  t.Error("search_metadata.id must be defined")
  return
}

searchArchive, err := client.SearchArchive(searchID)
if err != nil {
  t.Error(err)
  return
}

searchIDArchive := searchArchive["search_metadata"].(map[string]interface{})["id"].(string)
if searchIDArchive != searchID {
  t.Error("search_metadata.id do not match", searchIDArchive, searchID)
}

This code prints the search results from the archive. :)

Account API

auth := map[string]string{
 "api_key": "<secret_api_key>"
}
client := serpapi.NewClient(auth)
rsp, err = client.Account()
fmt.Println(rsp)

It prints your account information.

Basic examples in Go

    "q": "coffee",  }
  rsp, err := client.Search(parameter)

  if err != nil {
    fmt.Println("unexpected error", err)
    return
  }

  if rsp["search_metadata"].(map[string]interface{})["status"] != "Success" {
    fmt.Println("bad status")
    return

Advanced search API usage

Highly scalable batching

Search API features non-blocking search using the option: async=true.

• Non-blocking - async=true - a single parent process can handle unlimited concurrent searches.
• Blocking - async=false - many processes must be forked and synchronized to handle concurrent searches. This strategy is I/O usage because each client would hold a network connection.

Search API enables async search.

• Non-blocking (async=true) : the development is more complex, but this allows handling many simultaneous connections.
• Blocking (async=false) : it's easy to write the code but more compute-intensive when the parent process needs to hold many connections.

Here is an example of asynchronous searches using Go

 import (	
  "github.com/serpapi/serpapi-golang" 
  "fmt"
)

 func main() {

import (
	"fmt"
	serpapi "github.com/serpapi/serpapi-golang"
	"os"
	"time"
)

/***
 * The code snippet aims to improve the efficiency of searching using the SerpApi client using `async` mode.
 * The request are non-blocking which allows batching a large amount of query, and wait before fetching the result back.
 *
 * **Process:**
 * 1. **Request Queue:** The company list is iterated over, and each company is queried using the SerpApi client. Requests
 * are stored in a queue to avoid blocking the main thread.
 *
 * 2. **Client Retrieval:** After each request, the code checks the status of the search result. If it's cached or
 * successful, the company name is printed, and the request is skipped. Otherwise, the result is added to the queue for
 * further processing.
 *
 * 3. **Queue Processing:** The queue is processed until it's empty. In each iteration, the last result is retrieved and
 * its client ID is extracted.
 *
 * 4. **Archived Client Retrieval:** Using the client ID, the code retrieves the archived client and checks its status. If
 * it's cached or successful, the company name is printed, and the client is skipped. Otherwise, the result is added back
 * to the queue for further processing.
 *
 * 5. **Completion:** The queue is closed, and a message is printed indicating that the process is complete.
 *
 * * **Asynchronous Requests:** The `async: true` option ensures that search requests are processed in parallel, improving
 * efficiency.
 * * **Queue Management:** The queue allows requests to be processed asynchronously without blocking the main thread.
 * * **Status Checking:** The code checks the status of each search result before processing it, avoiding unnecessary work.
 * * **Queue Processing:** The queue ensures that all requests are processed in the order they were submitted.
 *
 * **Overall, the code snippet demonstrates a well-structured approach to improve the efficiency of searching for company
 * information using SerpApi.**

• source code: demo/demo_async.go

This code shows a simple solution to batch searches asynchronously into a queue. Each search takes a few seconds before completion by SerpApi service and the search engine. By the time the first element pops out of the queue. The search result might be already available in the archive. If not, the search_archive method blocks until the search results are available.

• Brand centric instead of search engine based
  • No hard-coded logic per search engine
• Simple HTTP client (lightweight, reduced dependency)
  • No magic default values
  • Thread safe
• Easy extension
• Defensive code style (raise a custom exception)
• TDD
• Best API coding practice per platform
• KiSS principles

Inspirations

The source code and coding style of this project are inspired by Go. The Go programming language provides native recommendations for building excellent software.

where:

• The end user implements the application.
• Client refers to SerpApi:Client.
• SerpApi.com is the backend HTTP / REST service.
• Engine refers to Google, Baidu, Bing, and more.

The SerpApi.com service (backend)

• executes a scalable search on engine: "google" using the search query: q: "coffee".
• parses the messy HTML responses from Google on the backend.
• returns a standardized JSON response. The class SerpApi::Client (client side / golang):
• Format the request to SerpApi.com server.
• Execute HTTP Get request.
• Parse JSON into Go Hash using a standard JSON library. Et voila!

Continuous integration

We love "true open source" and "continuous integration", and Test Drive Development (TDD). We are using RSpec to test [our infrastructure around the clock]) using Github Action to achieve the best QoS (Quality Of Service).

The directory spec/ includes specification which serves the dual purposes of examples and functional tests.

Set your secret API key in your shell before running a test.

export API_KEY="your_secret_key"
