I'am running Bitcoin-qt on Qt 4.8.3 on windows 7 64.

below is my .conf content in %appdata%/bitcoin folder


using curl 7.26.0 (i686-pc-mingw32), I run the following command:

curl --user 'bitcoinrpc' --data-binary '{"jsonrpc":"1.0","id":"curltext","method":"getinfo","params":[]}' -H 'content-type:text/plain;'

the pc ask for host password.

I have tried the .conf password and also the PC password (which is the one I log into my PC)

I always get error 401 (unauthorized) result.

Can anyone advice me where did I went wrong or how do I know which password it refer to?

You can also make a request by explicitly mentioning the username and password in the URI:


Making your request to this address should be sufficient.

So, full command:

curl --data-binary '{"jsonrpc":"1.0","id":"curltext","method":"getblockchaininfo","params":[]}' -H 'content-type:text/plain;' http://bitcoinrpc:ahything@

    Keep in mind however that Steven Roose's suggestion won't work if there's an "@" in the password. Also depending on the connection location, the URL may be visible. It is certainly less secure and not suitable for remote system access. – user27425 Jul 15 '15 at 1:53

I got it to work by adding the password to the --user value, separated with ":". So the example becomes:

curl --user bitcoinrpc:xxxxxxxxxxxxxxx --data-binary '{"jsonrpc":"1.0","id":"curltext","method":"getinfo","params":[]}' -H 'content-type:text/plain;'

Where "xxxxxxxxxxxxxxx" is the rpcpassword stored in the .conf file.

  • Have you tried ? curl --user bitcoinrpc --password xxxxxxxxxxxxxxx --data-binary '{"jsonrpc":"1.0","id":"curltext","method":"getinfo","params":[]}' -H 'content-type:text/plain;' – szydan Dec 30 '15 at 2:38
  • curl: option --password: is unknown – emisilva Dec 19 '16 at 13:29
