I'm looking to scrape some data for experimentation, but I ran into a problem when attempting to scrape Zillow using BeautifulSoup; I got hit with a 403 error. I used to do this a few years back without much trouble, so I'm wondering if there are better methods or alternative libraries I could use this time around. Also, does anyone know what the 403 error actually means?

You might want to check if Zillow has an API available for your needs, but be aware that it could be behind a paywall. An API could save you headaches, making the process smoother.
A 403 error typically means that the server is rejecting your request. Sometimes it can detect things like cookies or headers, so it’s worth checking on those. Just make sure your requests look like they come from a regular browser. If you can, try using a browser's developer tools to see what headers are sent with a successful request.
Another approach could be to build a search engine using something like Elasticsearch and Kibana. You can create a domain list for crawling, and once it’s set up, you can search through the data more efficiently.
Right, it's all about mimicking a real user. Sometimes changing your user-agent string helps as well!
