Fetch HTML

The /content endpoint instructs the browser to navigate to a website and capture the fully rendered HTML of a page, including the head section, after JavaScript execution. This is ideal for capturing content from JavaScript-heavy or interactive websites.

Basic usage

Go to https://example.com and return the rendered HTML.

Terminal window
curl -X 'POST' 'https://api.cloudflare.com/client/v4/accounts/<accountId>/browser-rendering/content' \
  -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer <apiToken>' \
  -d '{"url": "https://example.com"}'

Advanced usage

Navigate to https://cloudflare.com/ but block images and stylesheets from loading. Undesired requests can be blocked by resource type (rejectResourceTypes) or by using a regex pattern (rejectRequestPattern). The opposite can also be done, only allow requests that match allowRequestPattern or allowResourceTypes.

Terminal window
curl -X POST 'https://api.cloudflare.com/client/v4/accounts/<accountId>/browser-rendering/content' \
  -H 'Authorization: Bearer <apiToken>' \
  -H 'Content-Type: application/json' \
  -d '{
      "url": "https://cloudflare.com/",
      "rejectResourceTypes": ["image"],
      "rejectRequestPattern": ["/^.*\\.(css)"]
    }'

Many more options exist, like setting HTTP headers using setExtraHTTPHeaders, setting cookies, and using gotoOptions to control page load behaviour - check the endpoint reference for all available parameters.
