1. Forum Scanner- Checks if the BTC address has been posted in any BitcoinTalk thread
- Specifically flags mentions inside the Scam Accusations and Reputation boards
- Shows links to posts where the address was mentioned
The forum will be needing things like this but hence someone already created same tool, and even made a beta version of it. Not a discouragement, but if you intending continuing, meaning you have to engage the tool to be more advanced than the one in use.
2. Blockchain LookupUses a blockchain explorer API Blockstream, Mempool.space, or Blockchair as mentioned earlier to:- Get balance in BTC and fiat
- Count of transactions in/out
- Recent transaction activity with timestamps
I'm sure this development will take you decent time, explorers are easy to access already, just minority of people will be interested to explorer their address inside of a tool, lets save time and effort.
