Check new transactions on a btc address

To check new transactions on a Bitcoin (BTC) address, you can use various tools and APIs. Here are a few options:

1. Blockchain.com: You can use the Blockchain.com API to retrieve the transaction history of a specific Bitcoin address. You'll need to create an account and obtain an API key.

Example API call:

GET https://blockchain.info/q/addressbalance/<address>

Replace <address> with the Bitcoin address you want to check.

2. Bitcoin.com: Bitcoin.com provides a simple API to retrieve the transaction history of a specific Bitcoin address.

Example API call:

GET https://api.bitcoin.com/v3/address/<address>/transactions

Replace <address> with the Bitcoin address you want to check.

3. Etherscan: Although Etherscan is primarily an Ethereum blockchain explorer, it also supports Bitcoin transactions. You can use the Etherscan API to retrieve the transaction history of a specific Bitcoin address.

Example API call:

GET https://api.etherscan.io/api?module=proxy&action=eth_getTransactionByAddress&address=<address>&apikey=YOUR_API_KEY

Replace <address> with the Bitcoin address you want to check, and YOUR_API_KEY with your Etherscan API key.

4. Blockchain explorers: You can also use online blockchain explorers like Blockchain.com, Blockexplorer, or Bitcoin Block Explorer to view the transaction history of a specific Bitcoin address.

Example:

• Blockchain.com: https://blockchain.info/address/
• Blockexplorer: https://blockexplorer.com/address/
• Bitcoin Block Explorer: https://www.blockchain.com/btc/address/

Replace <address> with the Bitcoin address you want to check.

5. Command-line tools: You can also use command-line tools like bitcoin-cli or bitcoind to retrieve the transaction history of a specific Bitcoin address.

Example:

bitcoin-cli getaddressinfo <address>

Replace <address> with the Bitcoin address you want to check.

Remember to replace <address> with the actual Bitcoin address you want to check, and YOUR_API_KEY with your API key (if required).
