[Nxt] API of Nxt

[Come-from-Beyond]

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.

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

[datz]

NXT exchange launched!

Please help us test!

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

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

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.

For:

http://localhost:7874/nxt?requestType=getAccountTransactionIds&account=14862723975094572194&timestamp=0

I get {"errorCode":5,"errorDescription":"Unknown account"}

Why?

U r on a wrong branch. I see {"transactionIds":["15609747835883025669"]}

How do I get on the right branch?

[datz]

I setup from: http://nxtcrypto.wikia.com/wiki/How-To:InstallNRSLinux

How do I get on the right branch?

Delete *.nxt files and launch again.

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.

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.

I keep getting {"errorCode":4,"errorDescription":"Incorrect \"timestamp\""}

When trying to use requestType=getAccountTransactionIds

on version 0.4.7e, i tried different timestamps 0, -1, real timestamp

nothing works

For example:

http://localhost:7874/nxt?requestType=getAccountTransactionIds&account=6483973064837388393&timestamp=0

This works for me in an earlier version, but not in 0.4.7e

Did you change anything?


Thanks

[Come-from-Beyond]

Did you change anything?

No.

And it works:

Code:

{"transactionIds":["16327828505285932473","7776315672991437607","7478358102654400317","9038949217488707578","5107797978721572291","3056041568658981150","13938595992812911398","5860553720038071526","14088864536744330557","98233104059687517","3708542302478143606","11723261810965383682","8480031398450915391","4637952893059799971","4278983739975323329","11578788549066895383","17355434458110030026","15327384437462965022","11518685970067256485","6225568623338018976","5358668617356551382","7334304928632209196","11321968978650279956","14554751727556954823","96427141454859614"]}

Rename *.bak files to *.nxt, maybe ur copy of blockchain is inconsistent.

These are open for User and Bot.

You were right, the blockchain was corrupt.

Version 0.4.7e is really stable, good job
