Rendering Javascript | cURL

Learn to scrape JavaScript-rendered pages using ScraperAPI in cURL. Enable headless browser rendering with render=true for dynamic content, SPAs, and JS-heavy sites.

If you are crawling a page that requires you to render the Javascript on the page to scrape the data you need, then we can fetch these pages using a headless browser.

To render Javascript, simply set render=true and we will use a headless Google Chrome instance to fetch the page. This feature is available on all plans.

Pass the JavaScript rendering parameter within the URL:

• API REQUEST

curl "http://api.scraperapi.com/?api_key=APIKEY&url=http://httpbin.org/ip&render=true"

• PROXY MODE

curl -x "http://scraperapi.render=true:[email protected]:8001" -k "http://httpbin.org/ip"

Pass the parameter in the headers:

• API REQUEST

curl "https://api.scraperapi.com/?api_key=<API_KEY>&url=https://www.example.com" -H "x-sapi-render: true"

• PROXY MODE

curl -k --proxy “http://scraperapi:<API_KEY>@proxy-server.scraperapi.com:8001” https://www.example.com -H “x-sapi-render: true”
