Install the package

One line from your registry: npm, PyPI, RubyGems, Packagist, Maven, NuGet or go get.

Initialize with your token

Create the client with one of your Crawlbase tokens. The same token works everywhere.

Call the API

Pass any URL plus parameters like autoparse or screenshot, and read the response.
