Python interface to bitcoin's JSON-RPC API

python-bitcoinrpc

AuthServiceProxy is an improved version of python-jsonrpc.

It includes the following generic improvements:

• HTTP connections persist for the life of the AuthServiceProxy object
• sends protocol 'version', per JSON-RPC 1.1
• sends proper, incrementing 'id'
• uses standard Python json lib
• can optionally log all RPC calls and results
• JSON-2.0 batch support

It also includes the following bitcoin-specific details:

• sends Basic HTTP authentication headers
• parses all JSON numbers that look like floats as Decimal, and serializes Decimal values to JSON-RPC connections.

Installation

1. change the first line of setup.py to point to the directory of your installation of python 2.*
2. run setup.py

Note: This will only install bitcoinrpc. If you also want to install jsonrpc to preserve backwards compatibility, you have to replace 'bitcoinrpc' with 'jsonrpc' in setup.py and run it again.

Or simply install the library using pip:

pip install python-bitcoinrpc

Example

from bitcoinrpc.authproxy import AuthServiceProxy, JSONRPCException

# rpc_user and rpc_password are set in the bitcoin.conf file
rpc_connection = AuthServiceProxy("http://%s:%[email protected]:8332"%(rpc_user, rpc_password))
best_block_hash = rpc_connection.getbestblockhash()
print(rpc_connection.getblock(best_block_hash))

# batch support : print timestamps of blocks 0 to 99 in 2 RPC round-trips:
commands = [ [ "getblockhash", height] for height in range(100) ]
block_hashes = rpc_connection.batch_(commands)
blocks = rpc_connection.batch_([ [ "getblock", h ] for h in block_hashes ])
block_times = [ block["time"] for block in blocks ]
print(block_times)

Logging all RPC calls to stderr

from bitcoinrpc.authproxy import AuthServiceProxy, JSONRPCException
import logging

logging.basicConfig()
logging.getLogger("BitcoinRPC").setLevel(logging.DEBUG)

rpc_connection = AuthServiceProxy("http://%s:%[email protected]:8332"%(rpc_user, rpc_password))
print(rpc_connection.getinfo())

Produces output on stderr like

DEBUG:BitcoinRPC:-1-> getinfo [] DEBUG:BitcoinRPC:<-1- {"connections": 8, ...etc }

Socket timeouts under heavy load

Pass the timeout argument to prevent "socket timed out" exceptions:

rpc_connection = AuthServiceProxy(
    "http://%s:%s@%s:%s"%(rpc_user, rpc_password, rpc_host, rpc_port),
    timeout=120)

python-bitcoinrpc's Issues

Connection Problems with Python 3.x

Like title :

TypeError: getsockaddrarg: AF_INET6 address must be tuple, not int

how to install?

$ python setup.py 
usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
   or: setup.py --help [cmd1 cmd2 ...]
   or: setup.py --help-commands
   or: setup.py cmd --help

error: no commands supplied

Readme doesn't really tell me what I have to do.

[SOLVED] Cannot import python-bitcoinrpc

I am unable to import the package bitcoinrpc.

I have installed it in python2 and python3 using python3 -m pip python-bitcoinrpc/python -m pip python-bitcoinrpc AND by cloning the repo and editing the python environment in setup.py to my python2 and 3 path. Even after that I get the following errors:

Python2: ImportError: No module named authproxy
Python3: ModuleNotFoundError: No module named 'bitcoinrpc.authproxy'; 'bitcoinrpc' is not a package

Following is my code:

from bitcoinrpc.authproxy import AuthServiceProxy, JSONRPCException

# rpc_user and rpc_password are set in the bitcoin.conf file
rpc_user = "xxx"
rpc_password = "xxx"
rpc_connection = AuthServiceProxy("http://%s:%[email protected]:8332"%(rpc_user, rpc_password))

print(rpc_connection.get_info())

I have searched as much as i could but, cannot find anyting except for this bitcoin stackexchange question without an answer.

Is the setup broken or am I missing something?

Any help is appreciated. Thank you!

authentication in example outdated?

Authentication in the example did not work for me:
# rpc_user and rpc_password are set in the bitcoin.conf file
rpc_connection = AuthServiceProxy("http://%s:%[email protected]:8332"%(rpc_user, rpc_password))

Instead I followed this source:
https://github.com/bitcoin/bitcoin/blob/master/doc/JSON-RPC-interface.md#json-rpc-interface

Secure authentication: By default, Bitcoin Core generates unique login credentials each time it restarts and puts them into a file readable only by the user that started Bitcoin Core, allowing any of that user's RPC clients with read access to the file to login automatically. The file is .cookie in the Bitcoin Core configuration directory, and using these credentials is the preferred RPC authentication method. If you need to generate static login credentials for your programs, you can use the script in the share/rpcauth directory in the Bitcoin Core source tree. As a final fallback, you can directly use manually-chosen rpcuser and rpcpassword configuration parameters---but you must ensure that you choose a strong and unique passphrase (and still don't use insecure networks, as mentioned above).

The cookie-method worked for me. With the this mehtod, the example would look like this::
#The file .cookie in the Bitcoin Core configuration directory specifies your login credentials each time bitcoin core is started
rpc_connection = AuthServiceProxy("http://%s:%[email protected]:8332"%("__cookie__", "yourpassword")

RPC connection note closed

Hi, I have many threads in my wallet after using your code.
Is it possible to call connection.close somewhere?
Or should I use the more pythonic with?

My code is as follows:

class BaseRpcClient(BaseApiClient):

    def __init__(self):
        super(BaseRpcClient, self).__init__()
        self.api_cache = {}
        self.rpc_endpoint = None

    def get_api(self, node):
        self.rpc_endpoint = RpcMapper.get_rpc_addr(node)
        if self.rpc_endpoint not in self.api_cache:
            self.api_cache[self.rpc_endpoint] = \
                AuthServiceProxy(self.rpc_endpoint)
        self.api = self.api_cache[self.rpc_endpoint]
        return self.api

    def call_api(self, node, endpoint, *args):
        api = self.get_api(node)
        try:
            fn = getattr(api, endpoint)
            return fn(*args)
        except JSONRPCException as e:
            self.logger.error('JSON RPC ERROR HOST {} ERROR {}'
                              .format(self.rpc_endpoint, str(e)))

pip python-bitcoinrpc is not up-to-date

Specifically is missing this commit:

8c0114b

My experience:
sudo pip install python-bitcoinrpc

Then running this script:

from bitcoinrpc.authproxy import AuthServiceProxy, JSONRPCException
rpc_connection = AuthServiceProxy("http://%s:%[email protected]:8332"%("USER","PW"))
print(rpc_connection.getinfo())

simply outputs:
None

After editing /usr/local/lib/python2.7/dist-packages/bitcoinrpc/authproxy.py manually removing the "else" in line 146, the same script produces better results:

{u'connections': 10, u'errors': u'', u'blocks': 393219, u'paytxfee': Decimal('0E-8'), u'keypoololdest': 1451977259, u'walletversion': 60000, u'difficulty': Decimal('113354299801.47113037'), u'testnet': False, u'version': 110000, u'proxy': u'', u'protocolversion': 70010, u'timeoffset': -1, u'balance': Decimal('0E-8'), u'unlocked_until': 0, u'relayfee': Decimal('0.00005000'), u'keypoolsize': 101}

python-bitcoinrpc not in PyPi

This cannot be installed with pip (python package & dependency manager) since it is not in PyPi.

The ability to register the package with pypi was added in this pull request:
#7

All that should be needed is mentioned in that pull request, specifically
python setup.py register sdist upload

socket.timeout: timed out

Under Python 3.3, Ubuntu 14.04 I use the following code:
from bitcoinrpc.authproxy import AuthServiceProxy
x = AuthServiceProxy("....")
x.rpc_calls(...)

The Bitcoin RPC version I'm using is from the latest master branch.

Anyway, here is my observation: After making at least one successful RPC call the library will randomly throw a timeout exception that looks like this:
Original exception was:
Traceback (most recent call last):
File "", line 1, in
File "/usr/local/lib/python3.3/dist-packages/bitcoinrpc/authproxy.py", line 116, in call
response = self._get_response()
File "/usr/local/lib/python3.3/dist-packages/bitcoinrpc/authproxy.py", line 138, in _get_response
http_response = self.__conn.getresponse()
File "/usr/lib/python3.3/http/client.py", line 1147, in getresponse
response.begin()
File "/usr/lib/python3.3/http/client.py", line 358, in begin
version, status, reason = self._read_status()
File "/usr/lib/python3.3/http/client.py", line 320, in _read_status
line = str(self.fp.readline(_MAXLINE + 1), "iso-8859-1")
File "/usr/lib/python3.3/socket.py", line 297, in readinto
return self._sock.recv_into(b)
socket.timeout: timed out

I'm just wondering what the reason is for the timeout. It seems my Bitcoind daemon is never actually down. After the timeout occurs I can't issue any more RPC commands without the same exception but if I immediately reconnect with x = AuthServiceProxy("....") and issue the same failed RPC call it ends up working.

An obvious fix is to use a wrapper, but I'm wondering if it's a problem with this library or what reasons there are for this error.

I have confirmed the bug exists under multiple Python versions and multiple coind versions (hosted locally and remotely.) The RPC connection doesn't necessarily need to be open for a long time before the timeout occurs and there doesn't seem to be any pattern to the error.

TypeError: string indices must be integers

Hi,

Getting errors on the batch example. This is in Python 2.7.

>>> commands = [ [ "getblockhash", height] for height in range(100) ]
>>> block_hashes = rpc_connection.batch_(commands)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

decimal.InvalidOperation exception

I'm regularly calling getnetworkhashps(-1) to keep track of the network's estimated hash power for the current difficulty adjustment period. At the latest difficulty adjustment, around block 566,496 it temporarily peeked at "3.385206289794399E+20". Function EncodeDecimal couldn't handle numbers this big, and raised an exception:

Traceback (most recent call last):
  File "my_btc_test.py", line 19, in <module>
    networkhashps = rpc_connection.getnetworkhashps(-1)
  File "bitcoinrpc/authproxy.py", line 139, in __call__
    response = self._get_response()
  File "bitcoinrpc/authproxy.py", line 197, in _get_response

  File "bitcoinrpc/authproxy.py", line 77, in EncodeDecimal
    return float(round(o, 8))
decimal.InvalidOperation: [<class 'decimal.InvalidOperation'>]

I've reproduced the error with a simple example. The following code throws the same exception demonstrating the problem:

#!/usr/bin/python3
import decimal
o = decimal.Decimal("3.385206289794399E+20")
print(float(round(o, 8)))

A possible solution

Please consider merging @luke-jr's #63, that solves the issue.

OSError: [Errno 113] No route to host

hi
i have a windows pc in my lan (i have a qt-wallet installed and running), when i try to do a getinfo call from my laptop it give me this "OSError: [Errno 113] No route to host" but it's online how can i resolve this?
i set a "server=1" parameter and rpcallowip= in bitcoin.conf

if there's no login and password

if there's no login and password, how can I use this?

rpc_connection = AuthServiceProxy("http://%s:%[email protected]:8332"%(rpc_user, rpc_password))

passing None doesn't work.

License terms are not explicit

The docstring in authproxy.py mentions that there is a "Previous copyright, from python-jsonrpc/jsonrpc/proxy.py", which refers to the "GNU Lesser General Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version."

So, I suppose I can reasonably assume that python-bitcoinrpc is at least compatible with LGPL v2.1 or later. However, this still leaves some room for unclarity; I don't think that, the way it is now, I can be 100% certain that all of python-bitcoinrpc is available under LGPL v2.1 or later.

If it is the intention of all contributors to release their contributions under LGPL v2.1 or later (I hope this is the case), then please make it explicit.

Also, as a minor note: since the docstring says "You should have received a copy of the GNU Lesser General Public License along with this software", I think you should actually include a copy of the LGPL in the source tree.

add tests?

Hi, i'm wondering why this lib do not include tests.
Probably it will be good to "mock" from answers from bitcoin client.

HD wallet

with the latest version of bitcoind hd wallets are now available, is the python-bitcoinrpc compaitable with hd walllets?

authproxy failure under python 2.7.6

File "/home/ubuntu/appengine/apps/gethtoys/lib/bitcoinrpc/authproxy.py", line 137, in call

Works fine when I comment out line 137.

What am I missing?

Licensing and attribution

Within https://github.com/CryptocurrencyExplorer/CryptocurrencyExplorer/blob/main/Explorer/helpers.py in the classes JSONRPC and JSONRPCException, I've created derivative works of python-bitcoinrpc.
I'd like to know what the best way to attribute python-bitcoinrpc would be here, seeing as I'm not a lawyer.

Thank you :-)

Option to get raw json response?

Is there a clean way to have an api/option to get the raw json response (as string or better yet bytes for python3) instead of the pythonified version?

TypeError: getsockaddrarg: AF_INET address must be tuple, not int

---> Error

batch call parsing does not conform to JSON-RPC 2.0 standard

AuthProxy.batch_() should use ids to match responses with requests.

According to https://www.jsonrpc.org/specification: "The Response objects being returned from a batch call MAY be returned in any order within the Array. The Client SHOULD match contexts between the set of Request objects and the resulting set of Response objects based on the id member within each Object."

Now it is assumed that the server will keep the order the same.

Question/ Feature Request

I am sorry, don't know where to ask this. Maybe it is an issue in terms of a missing entry in the readme:

How am I supposed to install this?

I downloaded the zip with wget, unpacked it and ran

sudo ./setup build
sudo ./setup install

after changing the first line of the script to #!/usr/bin/python.

There is a bitcoinrpc file in my /usr/local/lib/python2.7/dist-packages/ now, but no jsonrpc. It is not surprising that I get the following error:

File "./bitcoinTest.py", line 2, in <module> from jsonrpc import ServiceProxy ImportError: No module named jsonrpc

So it seems jsonrpc is not getting installed? How can I install jsonrpc?

Python Bitcoin-RPC Connection Error?

My node is fully sync'd and operational (I've confirmed via commands with ssh) and I'm hoping to now use python-bitcoinrpc to interact with my node. Unfortunately I didn't get very far. Here is the code I'm running:

from bitcoinrpc.authproxy import AuthServiceProxy, JSONRPCException rpc_connection = AuthServiceProxy("http://%s:%[email protected]:8332"%(rpc_user, rpc_password)) best_block_hash = rpc_connection.getbestblockhash()

Where rpc_user and rpc_password is exactly what's in my bitcoin.conf file.

I disabled the ufw from the Raspibolt setup, but still getting the same error. My hunch is that it has to do with the port and since the Raspibolt setup is with Tor. Here is the info from my bitcoin.conf file:

server=1
txindex=1

# Network
listen=1
listenonion=1
proxy=127.0.0.1:9050
bind=127.0.0.1

# Connections
rpcuser=[rpcuser]
rpcpassword=[rpcpassword]
zmqpubrawblock=tcp://127.0.0.1:28332
zmqpubrawtx=tcp://127.0.0.1:28333


# Raspberry Pi optimizations
maxconnections=40
maxuploadtarget=5000

# Initial block download optimizations
dbcache=2000
blocksonly=1

I've been tweaking the address and port but still receive same error. Obviously a bit of a novice here but hoping to learn more!

Bitcoinrpc has an error with running of eloipool

Dears,

Whenever I running a Eloipool I saw following error on log file.
so I think that error related with bitcoinrpc.

TypeError: unsupported operand type(s) for +: 'NoneType' and 'bytes'

On python 3.6 When I try to open any connection I get the error in the title on line 100 in the AuthServiceProxy:
authpair = user + b':' + passwd

Memory error in batch mode

I am getting mempool tx from bitcoind in batch mode and sometimes getting this error:

responses = self._get_response()

Only getting sometimes, most of the times its working properly. Will try to reproduce exactly with a script

Note: harddisk and memory space is on box is normal

Support for RPC 2.0 protocol

What is needed to implement this?
Can I help somehow?

Thanks.

Could we get an official PyPi package update?
Thank you.

RPC SSL to btcd

I am trying to use bitcoind-ncurses to connect to btcd. I successfully got bitcoind-ncurses running on my box and had to make a small mod to it for it to support SSL (PRabahy/bitcoind-ncurses@d49a8c4). Even after doing that, I am having trouble getting to to connect.

I am very inexperience with python so began adding print statements to the code and believe I have the bug narrowed down to authproxy.py --> call --> self.__conn.request(...). I see that it makes the call, but never executes the print statement that I added on the next line. I assume that this means that it threw an exception.

I was suspicious of the call to httplib.HTTPSConnection(...) because it was passing None for the cert and key, but even after adding those it is still skipping my print statement.

I would love to eliminate some variables, but I am also having trouble getting bitcoind to run with RPC SSL and btcd requires RPC SSL (no option for insecure).

Cannot read block 9 transaction

Hi,

I was playing with the blochain using the python librairy 'bitcoinrpc' and bitcoin-core, however I can never read the transaction in block 9.

I even downloaded the blockchain a 2nd time thinking mine had a problem with a 2nd installation of bitcoin-core pointing to a different data directory and I still can't read block 9.

can you reproduce this problem? any idea why?

script for reading and displaying block 7, 8, 9, 10 :

from bitcoinrpc.authproxy import AuthServiceProxy
import traceback

RPC_ADDRESS="127.0.0.1:8332"
RPC_USER="u"
RPC_PASSWORD="p"

def display_block_info(rpc, block_number):
    print "-------- block {} start -------".format(block_number)
    block_hash = rpc.getblockhash(block_number)
    print "Block hash : " + block_hash
    block = rpc.getblock(block_hash)
    for tx in block[u'tx']:
        print "processing transaction " + tx
        print rpc.getrawtransaction(tx, True)
    print "-------- block {} end -------".format(block_number)
    print ""

if __name__ == "__main__":
    rpc = AuthServiceProxy("http://%s:%s@%s"%(RPC_USER, RPC_PASSWORD, RPC_ADDRESS))
    block_numbers = [7, 8, 9, 10]
    for block_number in block_numbers:
        try:
            display_block_info(rpc, block_number)
        except Exception as e:
            traceback.print_exc()
            print "-------- block {} end -------".format(block_number)
            print "")

result

fix for __init__.py to make it work from within other packages

a quick fix to your python-bitcoinrpc code: in init.py, s/jsonrpc.//
making it look like this:

from json import loads, dumps, JSONEncodeException, JSONDecodeException
from proxy import ServiceProxy, JSONRPCException

doesn't break anything, and makes it work when you stick it inside another package and try to import it (which i do with supybot :) )

Please fix the tag

Hi there,

I was trying to use pip to install your project based off the tag. I tried the following:

pip install -e git+https://github.com/jgarzik/[email protected]#egg=bitcoinrpc

This kept failing because your actual tag is v0.3-33-ge484743:

pip install -e git+https://github.com/jgarzik/[email protected]#egg=bitcoinrpc

If you type, "git tag" the tag will appear correctly, however if you run "git describe" on your repo you will see the actual tag. The tag gets into this state if you, cut a tag, and merge something into the existing, after the tag has been set. For more information please see:

https://www.kernel.org/pub/software/scm/git/docs/git-describe.html

I am a release engineer, and I encounter this every release week. :( I added this to my requriements.txt, so if you make any changes, the tag will change to 34 and thus it will break my "pip install -r requirements" command. I'm very big on sharing knowledge, so I hope you don't find this offensive. I just recently found out about this myself.

At work I am trying to get everyone to follow semantic versioning:

http://semver.org/

Perhaps you could just add a 1 at the end of your tag so it would be: 0.3.1

I love the project! Thanks so much for the great work.

Cheers,
Jon

Bug in __call__ related to bitcoind returning a bogus error

bitcoind returns an error when it actually wants to return a warning: bitcoin/bitcoin#7130
This causes a connection result with error=None as shown below. Unfortunately, python-bitcoinrpc misbehaves in this case, neither throwing an exception nor returning the result.

Two ways to fix this:

• either throw an exception
• or return the result

The second case works with bitcoind's weird warning behavior. It's fixed by #59

bitcoinrpc.authproxy.JSONRPCException: -342: non-JSON HTTP response with '500 Internal Server Error' from server

Hi, I'm using bitcoinrpc to fetch data using multiprocessing in python (20-40 processes at a time).

I'm frequently getting these errors:

exception catched by line 107: Traceback (most recent call last):
  File "mainF_v2_4_blocks.py", line 66, in block_processing
    block_hash = rpc1.getblockhash(block_height)

bitcoinrpc.authproxy.JSONRPCException: -342: non-JSON HTTP response with '500 Internal Server Error' from server

Here is timeout setting my connection string:

rpc1 = AuthServiceProxy( "http://%s:%s@%s:%s"%(rpc_user, rpc_password, rpc_host, rpc_port), timeout=86400)

and entry in bitcoin.conf:

rpcthreads=400
rpcworkqueue=1600
rpcservertimeout=7200

What can be the cause the above error? Any suggestions how to handle it? or do I need to change timeout settings?

Thanks.
