What are we doing wrong with the API?

http://111.111.111.111:7876/?request=sendMoney&secretPhrase=masked&recipient=12345678901234567890&amount=12&fee=1&deadline=900

Result is:

{"errorCode":1,"errorDescription":"Incorrect request"}

Changes in API

URL changed from localhost:7876/?request=XXX to localhost:7874/nxt?requestType=XXX

API can be accessed via HTTPS if port 7875 used.

Added http://localhost:7874/nxt?requestType=getMyInfo request, "host" can be used to set "allowedBotHosts" parameter in web.xml

Very good!

But we have to be careful; sendMoney gives valid-looking txid even if the transaction was spitted out and not sent to the blockchain. Any way to fix that?

Happily the client does not show the spitted tx.

{"transaction":"10170673123314889622"}

The client has a malfunction in that it does not show all the sendMoney transactions until much later. It does show some. Additional hazard is that even the blockchain explorer does not show the properly sent & accepted transactions until later. This has the potential to cause some serious mess.

API method request: a way to get a list of transactions pending inclusion in blocks (a la bitcoind getmemorypool).

Is there a way to check if an account is unlocked?
if I use wget to send the unlock request, how long will it stay unlocked?

Is there already a way to retrieve the last block without knowing its id?

so, how does the network know if an account is online?
I understand that starting a nxt client and opening my account in a web browser(online) will have a chance to earn the transaction fees.
Am I confused about UNLOCK and ONLINE?
If I unlock my account and quit the browser(without locking my account), do I have the chance to get trasaction fees?
If I stop the nxt client further, do I have the chance to get transaction fees?

Is there some changes about the UNLOCK request in 0.3.16 client?
I use a python script to unlock constantly,
when I restart the client, I got an error:
{u'responses': [{u'message': u'java.lang.NullPointerException', u'response': u'showMessage'}]}

I have to clean the whole nxt directory and restart th client to make the unlock script work again
I was using 0.3.14 and no such problem.

I like 0.3.16 that the numberOfAccounts shows the online accounts, right?
