fee for sendmany transactions blockchain.info api

[developerforbitcoin]

Hello friends..

Im newbie to bitcoins but done some RanD and developed an app which uses blockchain.info api send many transactions.

From the reference : https://blockchain.info/api/blockchain_wallet_api

I have used send_many transactions. But i have doubt in transaction fee.

My questions are :

what is the fee for all the transactions?

should i have to include fee for every address ?

for example: In a transaction i'm sending bitcoins to 2 addresses. for address 1 : transaction fee = 0.0005, for address 2 : transaction fee = 0.0005
option1 :{
$fee = (transaction fee for address 1) +  (transaction fee for address 2)

so in the server request URL http://blockchain.info/merchant/$guid/sendmany?password=$firstpassword&second_password=$secondpassword&recipients=$recipients&fee=$fee
}
option 2:
{
or $fee = 0.0005
http://blockchain.info/merchant/$guid/sendmany?password=$firstpassword&second_password=$secondpassword&recipients=$recipients&fee=$fee
}

which one option is correct?

Hope you guys understand my problem...

It is one fee per transaction. And to calculate a fee is based on the size meaning space of the transaction.

size meaning space of transactions means?

So can i put 0.0005 as the transaction fee in the server request URL that i have mentioned above?

or what is the minimum fee per transaction.

And as per my knowledge on bit coin, if we include minor fee then the transaction get confirmed quickly. Is that correct?
