Error making cURL in PowerShell

I run this command on the windows 10 power shell and it gives me an error.

  

curl --data '{"method": "web3_sha3", "params": ["0xe80966bc0e85e3e00bf7a2b6526aea7e8ecf4e0b"], "id": 1, "jsonrpc": "2.0"}' -H "Content-Type: application / json "-X POST localhost: 22000

EDIT I've changed the content-type to application / x-www-form-urlencoded and it keeps giving me error.

Any idea what may be happening?
