[caetanix]

when i run some rpc calls give this error... this an example

{
"jsonrpc": "2.0",
"method": "keypair_create",
"params": [12],
"id": 1
}

{
"error": {
"code": -999,
"message": "Not enough parameters provided"
},
"id": 1
}

There is another parameter required, specifying the crypto type (1 = SR25519 (default), 2 = ED25519)

So the body would be something like:

{"jsonrpc":"2.0","method":"keypair_create","params":[12,1],"id":6}

For use-case examples I would recommend the example GUI: https://github.com/polkascan/substrate-interface-gui/

Or the repos that contains all the elements: https://github.com/polkascan/substrate-interface
