Is orca not available in the US?

Excuse me, I've been trying to access the orca platform, but I'm having some trouble. Could you clarify for me if orca is indeed not available for use in the United States? I'm quite interested in the services they offer, and I'd like to ensure I'm not missing out due to any regional restrictions. Is there any specific reason why orca might not be accessible in the US, or is there perhaps an alternative service that you would recommend? Thank you for your time and assistance in this matter.
