Crawl

We will assume that you have installed the Spider package and exported your API key as an environment variable. If you haven't, please refer to the Getting Started guide.

Crawl a website and return the content.

from spider import Spider

app = Spider()
url = "https://spider.cloud"
crawled_data = app.crawl_url(url, params={"limit": 10})
print(crawled_data)

The crawl_url method returns the content of the website in markdown format as default. We set the limit parameter to 10 to limit the number of pages to crawl. The maximum amount of pages allowed to crawl per website. Remove the value or set it to 0 to crawl all pages.

Next we will see how to crawl with with different parameters.

Crawl with different parameters

The crawl_url method has the following parameters:

• url (str): The URL of the website to crawl.

the following are recommended parameters and can be set in the params dictionary:

• limit (int): The maximum amount of pages allowed to crawl per website. Remove the value or set it to 0 to crawl all pages.
• request_timeout (int): The maximum amount of time to wait for a response from the website.
• stealth (bool): Whether to use stealth mode. Default is False on chrome.
• visit the documentation for more parameters.

from spider import Spider

app = Spider()
url = "https://spider.cloud"
crawled_data = app.crawl_url(
    url, params={"limit": 10, "request_timeout": 10, "stealth": True}
)

print(crawled_data)

If you have a lot of params, setting them inside the crawl_url method can be cumbersome. You can set them in a seperate params variable that has the RequestParams type which is also available in the spider package.

from spider import Spider, spider_types

params: spider_types.RequestParamsDict = {
    "limit": 10,
    "request_timeout": 10,
    "stealth": True,
    # Easier to read and intellisense will help you with the available options
}

app = Spider()
url = "https://spider.cloud"
crawled_data = app.crawl_url(url, params)

print(crawled_data)
