[PYTHON] I tried to touch the API of ebay

Introduction

Be enrolled in the eBay Developers Program Please refer to the guide in here.

Try using the Finding API

Finding API Product search function on the eBay platform You can get search results for products listed on eBay with the API

I will run it with python

ebay_api.py

import requests
import csv

appkey =Obtained APP KEY
keywords =Keywords you want to search

URL = "http://svcs.ebay.com/services/search/FindingService/v1?OPERATION-NAME=findItemsByKeywords"\
    "&SERVICE-VERSION=1.0.0"\
    f"&SECURITY-APPNAME={appkey}"\
    "&RESPONSE-DATA-FORMAT=JSON"\
    "&REST-PAYLOAD"\
    f"&keywords={keywords}"


def get_page():
    request = requests.get(URL)
    products = request.json()

    for item in (products["findItemsByKeywordsResponse"][0]["searchResult"][0]["item"]):
        itemId = item["itemId"][0]
        title = item["title"][0]
        currency = item["sellingStatus"][0]["currentPrice"][0]["@currencyId"]
        price = item["sellingStatus"][0]["currentPrice"][0]["__value__"]

        data = {
            "itemId": itemId,
            "title": title,
            "currency": currency,
            "price": price
        }
        with open("eBayAPI.csv", "a") as csvfile:
            row = [
                data["itemId"],
                data["title"],
                data["currency"],
                data["price"]
            ]
            writer = csv.writer(csvfile)
            writer.writerow(row)


if __name__ == "__main__":
    get_page()

Value returned

def get_page():
    request = requests.get(URL)
    products = request.json()
    print(products)

The value returned here is returned in this way.

Please extract the required value by yourself. This time, I am trying to get the product ID, product name, currency, price.

        itemId = item["itemId"][0]
        title = item["title"][0]
        currency = item["sellingStatus"][0]["currentPrice"][0]["@currencyId"]
        price = item["sellingStatus"][0]["currentPrice"][0]["__value__"]

After that, the acquired product information is output as csv.

It seems that you can also search by filter or search in a specific store. I think that market research will be easier if it is used well.

Next, I will write about the article on ebaysdk.
