Oh man. Don't waste your time. There is a whole paper about trying to crack wallets by using the lattice attack. They tried most transactions already... . Try something new.
If you want to try anyways: best way is to modify bitcoin core so it saves all transactions r,s,z to a file. I have those modifications but won't give them away for free.

Here is the paper (very nice read and Nadia Heninge is really impressive woman):

Edit: Sorry, I did not read your OP completely. For only one address just check on blockchain.com (or similar blockchain browser) and get the values. You can easily automate it with something like beautifulsoup for python...
I can create such script but again not for free

.

Edit2: Ahh I forgot. Best method for particular address is to use electrum server api. It's very easy. I have the code.

I need a pubkey additionaly and this will be only monkey tests if youse random generator and not a real data...

I forget the key, added to the pseudocode. And the result you get from this pseudocode IS real data! Just as real and random as data you would have gotten from blockchain but acquired a lot faster.

Go nutzz:

Code:

var rng = new Random();
while (true)
{
byte[] zb = new byte[32];
rng.NextBytes(zb);
var (r, s) = Sign(zb);
DoSomething(r, s, zb);
}

I need a pubkey additionaly and this will be only monkey tests if youse random generator and not a real data...

I think need use a DER decoder... no more idea now... I continue search ...

These values aren't connected directly with an address. They construct the signature of a signed message. (Such as a signed transaction)

The signature is consisted of [r, s] and z is the hash of the message we want to sign. The s is created if you combine the message hash (z) and the private key (d). I doubt there's a script to get those if you just give the address, but there must be one if you enter the signature, the public key and the message.

Ok, how to get all r,s only ?
