How do I determine the balance of an address I don't own? (WebAPI or local API)

4

I have an arbitrary address. How can I get the current balance of the account through a Web API? ... how do I get it for a local API?

I'm also interested in all transaction history for that address. Let me know if the API can offer that as well.

Anyone with a local API solution to the same question? – qdot – 2014-01-12T09:16:44.587

You can query the unspent outputs of an address with this:

 http://blockchain.info/unspent?active=$bitcoin_address

You can get the transaction history for an address with this:

 http://blockchain.info/address/$bitcoin_address?format=json

For more information see http://blockchain.info/api/blockchain_api
