That site uses the sochain.com API, which limits too.

I don't have a copy of the blockchain, and all public APIs I found are slow or block after N amount of requests.

I have 130K+ Bitcoin addresses I need balance checked. I would like you to check them, and return me a list containing all addresses with a balance greater than 0, and their balance, preferably sorted by balance. Example:

<address1>, 20 BTC
<address2>, 10.5 BTC
etc.

I will pay in Bitcoin, and go first should I find you reputable enough. Comment here if you can do it and for how much, and I will send you a private message.
