I have tried to download mined Block-Headers from
https://blockchain.info/. I used a JSON method to download, and some other Java code to safe the mined Block-Headers into a txt. After a few thousand (9000) I couldn't download anymore, because of to many requests.
To remember, a Block-Header looks like this (
https://en.bitcoin.it/wiki/Block_hashing_algorithm):
0100000081cd02ab7e569e8bcd9317e2fe99f2de44d49ab2b8851ba4a308000000000000e320b6c

The Problem is I need to get more than a few thousand, I think there are actual about 388213 mined Block-Headers.
I don't need all of them, but about 350000 in a continuously row (It's important!).
Is there any other option (without single downloading them) to get the Block-Headers?
Thank you for your support.
