Suggestion for another blockexplorer

[naypalm]

Block explorer is frozen and I need a good alternative to scan 30,000 bitcoin addresses a day. Blockchain.info has banned me, yet I have a special API key.

I am all ears as they say.

Running bitcoind is not an option since last check it was well over 20 GB in size.

Have you tried Chain.com?  Their API is easy to use and is similar to blockchain in usage. They allow 10 requests per second, which should be more than enough. I've noticed their services drop quite frequently though   .  Another option is blocktrail but I haven't used them yet...
Block.io offers a wallet API similar to blockchain, create addresses, check balances, send transactions, payment forwarding etc.

how about https://chain.so/api ?

I just ran a test run with blockr.io and everything seems to be in the clear. I will check in the morning to see if I got myself banned again. If not, I will give your suggestions a try.

If you can't run bitcoind, you could use bitcoinj configured to store only the data you truly need. It depends on details such as whether you need to scan old transactions, and whether you know the addresses to scan in advance.

Blocktrail.com should be a good option , they are pretty awesome from what I heard .

Just use http://www.satoshiquiz.com/easybalance/easybalance.html with delay of 1s to avoid getting banned.
