Solve FunCaptcha from Arkose Labs

This type of task solves Arkose Labs captcha (or FunCaptcha) without a proxy. Task will be executed using our own proxy servers and/or workers' IP addresses.

Arkose Labs API provides information to the website owner about the solver's IP address. However it's worth trying first to bypass the captcha without a proxy, and if it doesn't work, switch to FunCaptchaTask with proxy.

Task creation object

Property Type Required Purpose
type String Yes FunCaptchaTaskProxyless
websiteURL String Yes Address of a target web page. Can be located anywhere on the web site, even in a member area. Our workers don't navigate there but simulate the visit instead.
websitePublicKey String Yes Arkose Labs public key.
funcaptchaApiJSSubdomain String No Custom Arkose Labs subdomain from which the Javascript widget is loaded. Look in the browser's Developer Console for URL like https://someservice-api.arkoselabs.com/v2/07070707-2000-0000-1111-888888888888/api.js, in this case the subdomain is "someservice-api.arkoselabs.com" and the public key is "07070707-2000-0000-1111-888888888888".
data String No An additional parameter that may be required by Arkose Labs implementation. Use this property to send "blob" value as an object converted to a string. See an example of what it might look like.
{"\blob\":\"HERE_COMES_THE_blob_VALUE\"}

Task solution object

Property Type Purpose
token String Token string required for interacting with the submit form on the destination page.
userAgent String User-Agent of the worker's browser. Use may want to use it when you submit the response token.
