Re: RPC Getting mempool transactions

You can call

Code:

getrawmempool true

(mind the true = verbose).

If you have to do multiple rpc calls, check out the JSON RPC 2.0 batching options (since bitcoind 0.7 aggregate multiple rpc calls in one). If you need more details check the bitcoin-core source and search after

Code:

static string JSONRPCExecBatch(const UniValue& vReq)

There is a pull request for mempool REST call (https://github.com/bitcoin/bitcoin/pull/6013).
