GET-requests to remote peers does not work in version 0.4.7e.
Answer: "Not allowed".
The problem is - "allowedBotHosts" in web.xml & NRS code.

This temporarily or permanently?
I am developing a mobile client and it all seriously hampered. Sad

Are there any root hosts that accept such requests and will take them in the future?

U should ask community in main Nxt thread for list of hosts who allow access to API calls.

How do I get on the right branch?

Delete *.nxt files and launch again.

hello，
I just made a statistic about all account's balance using API request. the total number is strange.
I start from the most recent block, and follow the 'previousBlock', go all the way down
until 'previousBlock'=None, and check transactions in each block, remember the 'sender'
and ' receipient'. then use getBalance api to get balance of each,and sumup all accounts's balance.
the number of accounts I got is 4205, which is the same as the output of getState.(when block height=25004)
but the total balance number is 18579288365!

I also find 2 accounts' balance is less than 0:
7577840883495855927 -999997985
15874940801139996458 -999997985
But I checked on http://87.230.14.1/nxt/nxt.cgi?action=10
these 2 accounts are ok.

did I make some mistakes, or is there a bug in the client/API?

hi nwecn,
you ar right, the blockexplorer is under constant attack to the node and also by automated query request.
the resulting database reorganization from this attacks de-sync's the db. therefore i wrote a note on top.
i am working to stop at least the query flooding as soon as possible. when done, it should be synced again.

great. now how can I tell if an address is a valid NXT address just from the address - no API calls?

Try http://localhost:7874/nxt?requestType=getAccountPublicKey&account=123

Cool. We are good to go, ready to provide exchange services for NXT.

I have a NXT exchange built for you guys.

I have one missing link: generating NXT accounts from secrets.

I do curve25519hex(shaValue256(secretKey)) but this generates an alphanumerical hex, not a pure numerical account prevalent in NXT.

How do I generate accounts?

http://localhost:7874/nxt?requestType=getAccountId&secretPhrase=MYSECRET

Edit: U could also take first 8 bytes and convert into unsinged long using little-endian notation.

Also, how do you create an account via API?

James

Account is created by the very 1st transaction.

Sorry for the newbie question, how do i associate a secret with an account?

Is the account a SHA 256 of a SHA 256 of a secret?

James

Secret is mapped to account id via Curve25519(SHA256(secret))
