If I enter that in the browser, I get a bunch of JSON with loads of data about the listings. Right-click the row of the response you want, and select “Copy URL”. Browse around to see if you find anything cool.įinally once you find a response with cool data, you need to get its URL so you can make your own request. Click the Response tab to show the data returned by that network event.
To browse through the data content of each response, click on the row, then a new “details window” will pop up on the right. What we are looking for will probably be a GET, but it’s possible for it to be something else if the web devs are doing something weird. XHR stands for XMLHttpRequest, which is what the frontend will use to make an HTTP request to the backend.
Click the XHR button to see only XHR events. Several rows should appear in the network tab. To clear the saved requests, click the trash can icon: Since Airbnb has the option “Search as I move the map”, I figured I could clear the Network tab first then move the map so I’d have a much smaller haystack to search through. There are quite a few requests to wade through.

The Network tab in Firefox’s Developer Tools (hit Ctrl+Shift+Q in plain old vanilla Firefox for it to pop up) is a powerful tool that lets you examine all the network traffic generated by the code running on the website you’re viewing. Watching Network Traffic with Firefox Developer Tools js resources are minified and obfusticated. I briefly looked at the JavaScript sources to see how this worked but found out the. I knew that Google Maps API doesn’t store pin locations – you have to construct the markers with JavaScript in the browser for pins to show up. I stumbled upon the JSON API because I wanted to scrape the latitude and longitude of the pins on their embedded Google Maps map.

Let’s go through and find how to access their backend API to scrape data about listings in a given area. Just nice, simple JSON.Ī uses this kind of framework (specifically Backbone and Handlebars, I think?). I’m going to show you how to find the URL to access that dynamic content so you can easily scrape data from a site, without lxml or BeautifulSoup or CSS selectors or XPath. Some sites use frontend frameworks which render dynamic content by loading a JSON or XML file from their backend to populate the user-facing site. I was trying to help someone with a web scraping task today, and stumbled upon an interesting technique to find hidden APIs to scrape data from certain websites.
