How to scrape walmart.com?

Walmart is relatively easy to scrape as it's mostly static content with a few dynamic elements so headless browser use is not required.

That being said, Walmart has a lot of anti-scraping mechanisms in place, so it's recommended to use a reliable web scraping service that can bypass the constantly changing anti-scraping measures. See benchmarks for the most up-to-date results.

Walmart's HTML datasets can be difficult to parse just because of sheer data point scale however many of the datapoints can be accessed through NextJS framework variables walmart is using. To do this look for the __NEXT_DATA__ variable in the HTML source.

import json
from parsel import Selector
# install using `pip install zenrows`
from zenrows import ZenRowsClient

# create an API client instance
client = ZenRowsClient(apikey="YOUR API KEY")

# create scrape function that returns HTML parser for a given URL
def scrape(url: str, country: str="", render_js=False, headers: dict=None) -> Selector:
    api_result = client.get(
        url,
