I am running a full node which accepts incoming connections.

Here is my config file:


Here is my swift code to curl to the node:

let url = URL(string: "http://bitcoinrpc:[email protected]:8333")
    var request = URLRequest(url: url!)
    request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
    request.httpMethod = "GET"
    request.httpBody = "{\"jsonrpc\":\"1.0\",\"id\":\"curltext\",\"method\":\"getinfo\",\"params\":[]}".data(using: .utf8)

        let task = URLSession.shared.dataTask(with: request) { (data, response, error) -> Void in

            do {

                if error != nil {


                } else {

                    if let urlContent = data {

                        do {

                            let jsonAddressResult = try JSONSerialization.jsonObject(with: urlContent, options: JSONSerialization.ReadingOptions.mutableLeaves) as! NSDictionary

                            print("jsonAddressResult = \(jsonAddressResult)")

                        } catch {




I am using port 8333 and the static IP I set is

I get the following error when executing the code:

8333 is the node connection port. Since you didn't change the RPC port in the config file, the port you should connect to is 8332.

  • Thank you! also for anyone having the same issue, I needed to change the request.httpMethod = "GET" to "POST" and the "getinfo" method to "getwalletinfo". :)
