+You can pass your proxy as an additional argument for methods: recaptcha, funcaptcha, geetest, geetest v4, hcaptcha, keycaptcha, capy puzzle, lemin, turnstile, amazon waf, Cutcaptcha, Friendly captcha, MTCaptcha, DataDome, CyberSiARA and etc. The proxy will be forwarded to the API to solve the captcha.
