The other and best method of extracting data from Yahoo Finance and other financial websites is to use an online scraping tool such as Crawlbase’s Crawling API.

The URL displays the HTML or XML page containing the scraper’s data, which returns the requested information.
Once the information has been collected, the scraper may examine the data shown in the target URL. Afterward, it will identify the necessary data for extraction and run the execution code. Once the data has been scraped, it is translated and saved in the desired format.
Sign up for a Crawlbase account and select the Crawling API option under the dashboard. You’ll find the API token with the first 1000 free requests. Normally, you’ll use a normal token. Then for JavaScript (real browsers), you’ll use a different token because, In some cases, a normal token won’t work, either because the site only works with JavaScript browsers or because JavaScript on the client side renders the content you need. The API response status will be provided in HTML/JSON as defined during the API call.
