Using Google Maps Place Results API from SerpApi

#webscraping #tutorial #python #programming

Intro

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

In order to successfully extract Google Maps Place Results, you will need to pass thedata parameter, this parameter is responsible for a specific place. You can extract this parameter from local results. Have a look at theUsing 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.

What will be scraped

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 underSerpApi Status page.

Full Code

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

fromserpapiimportGoogleSearchimportos,jsonparams={# 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 backendresults=search.get_dict()# JSON -> Python dictlocal_data_results=[{'data_id':str(result['data_id']),'latitude':str(result['gps_coordinates']['latitude']),'longitude':str(result['gps_coordinates']['longitude'])}forresultinresults['local_results']]place_results=[]forresultinlocal_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))

Preparation

Install library:

pip install google-search-results

google-search-results is a SerpApi API package.

Code Explanation

Import libraries:

fromserpapiimportGoogleSearchimportos,json

Library	Purpose
`GoogleSearch`	to scrape and parse Google results usingSerpApi 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 theparams 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}

Then, we create asearch object where the data is retrieved from the SerpApi backend. In theresults dictionary we get data from JSON:

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

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

Data such asdata_id,latitude andlongitude are extracted from each local result. These data will be needed to form thedata 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'])}forresultinresults['local_results']]

Declaring theplace_results list where the extracted data will be added:

place_results=[]

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

forresultinlocal_data_results:# data extraction will be here

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}

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 thedata parameter, which is only required iftype is set toplace. 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"])

This will form a string that looks like this:

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

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

Then, we create asearch object where the data is retrieved from the SerpApi backend. In theresults dictionary we get data from JSON:

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

Append data from this place in theplace_results list:

place_results.append(results['place_results'])# title = results['place_results']['title']# rating = results['place_results']['rating']# reviews = results['place_results']['reviews']

📌Note: 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))
