If I have, say 20, priv/pub key pairs in my wallet which bitcoin API calls do I use to:
- Select a specific privpub key pair.
- Generate a new bitcoin address (using the selected private key)
Which API call creates new bitcoin addresses

bitcoind getnewaddress [account]
Where account is the name you want the new address associated with.
Here is the API documentation.

In order to get your private keys, you have to:
- Unlock your wallet if it is encrypted by calling: WalletPassphrase
- Call ListReceivedByAddress with arguments: 0, true to get all available addresses
- Iterate through those addresses and for each of them that you want to grab the key pair call DumpPrivKey
To get a new address just call the GetNewAddress method.
OK but getnewaddress does not take the private key as an argument. How do I create a new address using a selected private key? – user11286 – 2013-12-28T13:55:07.700
There is no method which accepts a private key as input. However what you can do is take an address from a specific key from your wallet and then if you call
getnewaddresswith that account, the new address will be associated with that private key. – Loourr – 2013-12-28T16:14:02.393what if I only have one account that uses all the private keys how do I associate a new address with a specific key then? – user11286 – 2013-12-29T15:09:27.563
you cant have an account associated with more then one key, however you can have as many accounts as you want associated with a given key. – Loourr – 2013-12-29T18:14:40.053
but guys like blockchain.fino (which is a shared e-wallet) allows you to have a unique private key per user. I presume blockchain.info also only has one wallet on bitcoind with user accounts managed in a separate db. Thus if a user transfer funds from his account he uses his own private key to generate a unique address. – user11286 – 2013-12-30T08:07:06.457
You can use things like pywallet to manage lots of different
