Which program should I use to scan the blockchain?

[Sword Smith]

I would like to develop some bitcoin functionalities such that a server could scan extract information from the blockchain and also make and publish transactions and so on. I expect to write the program in PHP or maybe in Python. Should I use the API for the Bitcoin QT client, should I use something for Armory or should I use something else?

I know this question has been asked before but things may have changed since then.

I would say it depends on what exactly your trying to achieve. Is the information something that could be pulled from a site like Blockchain? If so I would use their own API which they provide for free. My programming knowledge is limited so hopefully someone can clarify more for you but I see no reason as to why you can't use the API from Blockchain.

Blockchain.info's API would probably be the most convenient option, but if you don't want to depend on an external service then you can still access the same information with bitcoind, possibly with a separate database of some sort to track blocks if necessary (depending on what information you need).

I have been looking at bitcoind now for me time since I would like to not depend on a 3^rd party. But what about Armory, where can I find information about Armory's API?

I think its better to run Bitcoin-QT as a full node and read data from it. You may use Abe for the same. I'm also looking for a similar service (independent of 3rd party) for some time as blockchain.info is failing time and again. Would be great if Abe is modified more and published. My short of knowledge in Python is stopping me.

The primary issue is that I would like to seperate a list of watch addresses and names for these watch addresses from the private keys associated with these addresses. And I would also like to automate the transactions which should be signed on a computer which only has connection to the server and not the internet as such.
