Above i shared my script in bash.
The copy key is because the other place is runing a proxmox (second) and IP is dynamic.
So, o connect, accept the new fingerprint and connect.
I test the connectio before run syncoid, this is to avoid the syncoid create more then one snapshot (sometimes he lots the hard drive, so this test avoid this sucessful).
So, i will try to adopt this script to execute via curl (api) this replication. If someone has the way i will test.

echo "Replication Active"
# IF you can connect to the destination ssh port, do the rest. If not, ignore the following lines and skip straight to count to start the script again.
if nc -zw3 $REMOTE_IP $REMOTE_PORT; then
echo "Connection successful. Testing ssh."
