Frequently asked questions

Everything you need to know about WINTR API, proxies, web scraping, and data parsing.

What is WINTR?

WINTR is a web scraping and parsing service which features a set of tools concentrated in an application programming interface (API) that allows companies and developers to crawl any webpage, retrieve its HTML content, and parse it to get a custom structured dataset, request status, headers, and cookies.

Why do I need to scrape data?

There are many use cases for the WINTR web scraping and parsing service, and in order to stay competitive, almost every company out there takes part in data gathering in some form or other. It's mainly used for sales, marketing, finance, operations, strategy, growth, and research purposes. For example, an internet-based company will need to obtain data about its market in order to improve its search engine optimization.

What is data parsing?

Data parsing is the art of breaking a data block into smaller chunks according to some predefined rules. When retrieving data from a webpage, you will get the whole HTML content of this one. With data parsing, for example, you can split it in order to get only the page title and description.

What is the custom extraction offer?

Here at WINTR, we also provide custom data extraction using our own API for companies and Non-programmers. We can provide custom data with custom labels in a custom format, both periodically or through a custom scraping solution. Please have a look at our custom extraction section and tell us more about your project to get a quote.

What is a Javascript rendered webpage?

Some websites, like single-page applications (SPA), render their content using Javascript. And oftentimes, in the case of an asynchronous Javascript and XML technology (AJAX), those webpages can be complicated to get data from, due to the fact that they require human user behaviors. Thankfully, however, WINTR web scraper uses headless browsers in order to easily succeed in that task.

How do I crawl a webpage?

In order to crawl a webpage, you will first need to create an account on the WINTR website to get an API key, Our free plan allows up scraping of up to 1000 webpages. You can try our service without having to write a single line of code by using our online API tester.

How do I crawl a Javascript rendered webpage?

When it comes to Javascript rendered webpages, all you have to do is set the "jsrender" parameter to TRUE in order to scrape through a headless browser instance. There are other options that you can also set to select which element of the page you want to load and render to speed the request up. You can also wait for a certain amount of time, or for an HTML element to appear, before getting a response from the API. For more information, please take a look at our API documentation.

How do I parse gathered data?

Another great tool that we offer is a way to completely customize the data you get from scraping by setting the "outputschema" parameter as a JSON object containing the keys and values (CSS selectors) you need to retrieve. Additionally, it is possible to filter that data using Javascript functions. For more information, please take a look at our API documentation.

How can I parse the HTML to JSON?

You can customize fetched data by using the "outputschema" parameter, or get in touch with us for a custom scraping solution by checking out this custom extraction section.
