Title: APIs to know the balance of a bitcoin address
Post by: xcbtrader on September 02, 2016, 10:12:50 AM

Good morning everyone.

I'm looking for the different APIs to see the balance of a bitcoin address.

Currently I have checked:

https://blockchain.info/q/addressbalance/ (https://blockchain.info/q/addressbalance/)

https://blockexplorer.com/api/addr/ (https://blockexplorer.com/api/addr/)
https://www.bitgo.com/api/v1/address/ (https://www.bitgo.com/api/v1/address/)

And this:

https://chain.api.btc.com/v3/address/ (https://chain.api.btc.com/v3/address/)

Added news APIS (9/9/2016):

Added news APIs (10/9/2016):

To use these APIs do not need any registration.

Does anyone know any other API that is not here?

Surprising! I hadn't imagine there could be so many, considering that it's so easy to create a new address, I thought few people would find it useful to watch a given one. Well, I was wrong...

wow, nice list i haven't searched apis this way. To lower the amount of request to some well known wallet/api services which limit request per second/hour, this could help by requesting balance check with these free api and just using those wallets api to make new address only.

Thanks!!!

It is very easy to create new address with code, for example in Python. Don't need a wallet.

Thanks for the information, are you planning on reviewing them all? What are their strengths and weaknesses? What do you use them all for?

The idea of this post is simply a compilation of APIs.
It took me long to find this information, validate, and I think it can be a good contribution to the people of the forum.

thanks for this, i was looking for more APIs to use in my watch only bitcoin wallet. i am currently only using blockchain.info i guess i will only add blockr.io and maybe blockexplorer that should be enough.

p.s. please add all of them in the first post so we can see them all in one place.

Also Blockonomics api (https://www.blockonomics.co/views/api.html#balance)

I suggest you have a look a moneywagon project (https://github.com/priestc/moneywagon).
Using it you can use bitcoin api, without worrying about backend service.
It will do roundrobin/random selection of service, or also can do paranoid checking to make sure balance is correct
across several services. It also supports most of the existing API services

what do you call this if not JSON response :)

Code:

{"response": [{"confirmed": 189412205, "addr": "1dice8EMZmqKvrGE4Qc9bUFf9PX3xaYDp", "unconfirmed": 012211 }, {"confirmed": 746599881, "addr": "1dice97ECuByXAvqXpaYzSaQuPVvrtmz6", "unconfirmed": 0}]}

i Call with python program, no errors in others APIs but, this not work:

Code:

addr = '1dice8EMZmqKvrGE4Qc9bUFf9PX3xaYDp'

request = 'https://www.blockonomics.co/api/balance/' + addr
response = requests.get(request)
content = response.json()
content = int(content['response']['confirmed'])

i receive this error:

   content = response.json()
  File "/usr/local/lib/python2.7/dist-packages/requests/models.py", line 812, in json
   return complexjson.loads(self.text, **kwargs)

Code:

addr = '1dice8EMZmqKvrGE4Qc9bUFf9PX3xaYDp'

request = 'https://www.blockonomics.co/api/balance/' + addr
response = requests.get(request)
content = response.json()
content = int(content['response']['confirmed'])

####

your problem is in your first line of code `request` you should send the request to the URI without the appended `addr` instead you should put the `addr` inside of a HttpRequest (equivalent in python) and `post` it.

also you need to add a header with the ApiKey

Code:

POST https://www.blockonomics.co/api/balance
Request body: {"addr": <Whitespace seperated list of bitcoin addresses/xpubs>}

p.s. everywhere i look i see people are using python these days, i am getting depressed for choosing to learn C# 8)

Actually API key is not needed. This should work:

Code:

import json
import requests
addr = '1dice8EMZmqKvrGE4Qc9bUFf9PX3xaYDp'

request = 'https://www.blockonomics.co/api/balance' 
response = requests.post(request, data=json.dumps({"addr":addr}))
content = response.json()
balance = content['response'][0]['confirmed']

Works fine...
