Using Google Maps Place Results API from SerpApi

Intro

In this blog post, we'll go through the process of extracting data from Google Maps Place results using Python. You can look at the complete code in the online IDE (Replit).

In order to successfully extract Google Maps Place Results, you will need to pass the data parameter, this parameter is responsible for a specific place. You can extract this parameter from local results. Have a look at the Using Google Maps Local Results API from SerpApi blog post, in which I described in detail how to extract all the needed data.

If you prefer video format, we have a dedicated video that shows how to do that: Web Scraping Google Maps Place Result with SerpApi and Python.

Why using API?

There're a couple of reasons that may use API, ours in particular:

  • No need to create a parser from scratch and maintain it.
  • Bypass blocks from Google: solve CAPTCHA or solve IP blocks.
  • Pay for proxies, and CAPTCHA solvers.
  • Don't need to use browser automation.

SerpApi handles everything on the backend with fast response times under ~2.5 seconds (~1.2 seconds with Ludicrous speed) per request and without browser automation, which becomes much faster. Response times and status rates are shown under SerpApi Status page.

Full Code

If you just need to extract all available data about the place, then we can create an empty list and then append extracted data to it:

from serpapi import GoogleSearch
import os, json

params = {
    # https://docs.python.org/3/library/os.html#os.getenv
    'api_key': os.getenv('API_KEY'),        # your serpapi api
    'engine': 'google_maps',                # SerpApi search engine 
    'q': 'Starbucks',                       # query
    'll': '@40.7455096,-74.0083012,15.1z',  # GPS coordinates
    'type': 'search',                       # list of results for the query
    'hl': 'en',                             # language
    'start': 0,                             # pagination
}

search = GoogleSearch(params)               # where data extraction happens on the backend
results = search.get_dict()                 # JSON -> Python dict

local_data_results = [
    {
        'data_id': str(result['data_id']),
        'latitude': str(result['gps_coordinates']['latitude']),
        'longitude': str(result['gps_coordinates']['longitude'])
    }
    for result in results['local_results']
]

place_results = []

for result in local_data_results:
    data = '!4m5!3m4!1s' + result['data_id'] + '!8m2!3d' + result['latitude'] + '!4d' + result['longitude']

    params = {
        # https://docs.python.org/3/library/os.html#os.getenv
        'api_key': os.getenv('API_KEY'),    # your serpapi api
        'engine': 'google_maps',            # SerpApi search engine
        'type': 'place',                    # list of results for the query,
        'data': data                        # place result
    }

    search = GoogleSearch(params)
    results = search.get_dict()

    place_results.append(results['place_results'])

print(json.dumps(place_results, indent=2, ensure_ascii=False))
Enter fullscreen mode Exit fullscreen mode

Preparation

Install library:

pip install google-search-results
Enter fullscreen mode Exit fullscreen mode

google-search-results is a SerpApi API package.

Code Explanation

Import libraries:

from serpapi import GoogleSearch
import os, json
Enter fullscreen mode Exit fullscreen mode
Library Purpose
GoogleSearch to scrape and parse Google results using SerpApi web scraping library.
os to return environment variable (SerpApi API key) value.
json to convert extracted data to a JSON object.

At the beginning of the code, you need to make the request in order to get local results. Then place results will be extracted from them.

The parameters are defined for generating the URL. If you want to pass other parameters to the URL, you can do so using the params dictionary:

params = {
    # https://docs.python.org/3/library/os.html#os.getenv
    'api_key': os.getenv('API_KEY'),        # your serpapi api
    'engine': 'google_maps',                # SerpApi search engine 
    'q': 'Starbucks',                       # query
    'll': '@40.7455096,-74.0083012,15.1z',  # GPS coordinates
    'type': 'search',                       # list of results for the query
    'hl': 'en',                             # language
    'start': 0,                             # pagination
}
Enter fullscreen mode Exit fullscreen mode

Then, we create a search object where the data is retrieved from the SerpApi backend. In the results dictionary we get data from JSON:

search = GoogleSearch(params)     # where data extraction happens on the backend
results = search.get_dict()       # JSON -> Python dict
Enter fullscreen mode Exit fullscreen mode

At the moment, the first 20 local results are stored in the results dictionary. If you are interested in all local results with pagination, then check out the Using Google Maps Local Results API from SerpApi blog post.

Data such as data_id, latitude and longitude are extracted from each local result. These data will be needed to form the data parameter, which will be needed later:

local_data_results = [
    {
        'data_id': str(result['data_id']),
        'latitude': str(result['gps_coordinates']['latitude']),
        'longitude': str(result['gps_coordinates']['longitude'])
    }
    for result in results['local_results']
]
Enter fullscreen mode Exit fullscreen mode

Declaring the place_results list where the extracted data will be added:

place_results = []
Enter fullscreen mode Exit fullscreen mode

Next, you need to access each place separately by iterating the local_data_results list:

for result in local_data_results:
    # data extraction will be here
Enter fullscreen mode Exit fullscreen mode

These parameters are defined for generating the URL for place results:

params = {
    # https://docs.python.org/3/library/os.html#os.getenv
    'api_key': os.getenv('API_KEY'),    # your serpapi api
    'engine': 'google_maps',            # SerpApi search engine
    'type': 'place',                    # list of results for the query,
    'data': data                        # place result
}
Enter fullscreen mode Exit fullscreen mode
Parameters Explanation
api_key Parameter defines the SerpApi private key to use.
engine Set parameter to google_maps to use the Google Maps API engine.
type Parameter defines the type of search you want to make. place - returns results for a specific place when data parameter is set.
data Parameter must be set in the next format: !4m5!3m4!1s + data_id + !8m2!3d + latitude + !4d + longitude.

Additionally, I want to talk about the value that is written to the data parameter, which is only required if type is set to place. In that case, it defines a search for a specific place. It must be built in the following sequence:

data = (
    "!4m5!3m4!1s"
    + result["data_id"]
    + "!8m2!3d"
    + result["latitude"]
    + "!4d"
    + result["longitude"]
)
Enter fullscreen mode Exit fullscreen mode

This will form a string that looks like this:

!4m5!3m4!1s0x89c259b7abdd4769:0xc385876db174521a!8m2!3d40.750231!4d-74
Enter fullscreen mode Exit fullscreen mode

Parameter can also be used to filter the search results. You can visit Google Maps website, set filters you want and simply copy the data value from their URL to SerpApi URL.

Then, we create a search object where the data is retrieved from the SerpApi backend. In the results dictionary we get data from JSON:

search = GoogleSearch(params)
results = search.get_dict()
Enter fullscreen mode Exit fullscreen mode

Append data from this place in the place_results list:

place_results.append(results['place_results'])
# title = results['place_results']['title']
# rating = results['place_results']['rating']
# reviews = results['place_results']['reviews']
Enter fullscreen mode Exit fullscreen mode

๐Ÿ“ŒNote: If you want to extract some specific fields, then in the comment above I gave an example of how this can be implemented.

After the all data is retrieved, it is output in JSON format:

print(json.dumps(place_results, indent=2, ensure_ascii=False))
Enter fullscreen mode Exit fullscreen mode
