I can help you. Here is a step-by-step guide on how to retrieve the number of confirmed transactions from a Bitcoin-QT (Bitcoin-Qt) node with an empty wallet using the QRpc API:

Prerequisites

• You must have a Bitcoin-QT node configured and running.

• You must have the bitcoin-qt-rpc package installed in your project. If you don’t have it installed, you can do so by running pip install bitcoin-qt-rpc (Linux/Mac) or conda install -c conda-forge bitcoin-qt-rpc (Windows).

Get the QRpc API URL

To connect to the QRpc API, you need to get its URL. You can do this by running the following command:

bitcoin-qt-rpc --list-wallets

`

This will list all the wallets available on your node, including those with empty wallets. Write down the URL of the wallet you want to retrieve information from.

Return Confirmation Count

Once you have the QRpc API URL, you can use it to retrieve the confirmation count for a specific transaction. Here is an example:

import requests





Set the QRpc API URL and wallet ID you want to retrieve data from
url = "wss://localhost:8532/QRL-MAIN-SLOT"

Set the transaction ID
tx_id = 1234567890

Set the confirmation count query parameter
query = f"?confirmed={int(tx_id)}/"

Send a GET request to the QRpc API with the query parameters
response = requests.get(url + query)

Check if the response was successful
if response.statuscode == 200:

Parse the JSON response
data = response.json()

Print the transaction confirmation count
print(data["result"]["confirmed"])
else:
print("Error:", response.text)

In this example we send a GET request to the QRpc API with the transaction ID set to the query parameter “confirmed”. We then parse the JSON response and print the transaction confirmation count.

Tips and Variations

• You can modify the query variable to include other parameters, such as the block number or hash.

• You can use the built-in query parameter parser in the bitcoin-qt-rpc package to handle different query parameter formats.

• If you need to return data from a wallet with an empty wallet, you should check if there are any pending transactions in the wallet before attempting to return its confirmation count.

I hope this helps! Let me know if you have any questions or if I can help you with anything else.
