archive.today fails, the site presents a captcha challenge

[Igetin]

When trying to archive an URL to archive.today through archivenow --is URL, it always returns:

Error (The Archive.is): 429 Client Error: Too Many Requests for url: https://archive.is/submit/

I have Firefox and geckodriver installed and available in my PATH.

When submitting a URL on the site regularly through a browser, the site returns 429 on submit and requires the completion of a reCAPTCHA challenge, and then proceeds to archive the URL.
