To confirm as well, safepal leverages cloudflare DNS for their site - if they also use this to protect their API (which I assume they do) you're going to run into massive issues bruteforcing their API - it isn't going to work... you 100% will get throttled.

As others have mentioned, try seeing if you can get access to a file instead, and running code against that. Leveraging an API won't get you what you need without getting blacklisted/IP banned.
