I'm using this component in my HomeAssistant installation and when it's configured it throws this exception:

A few other users are experiencing the same issue here: home-assistant/core#9907

I have this error in python 3.6 and I believe is due to a parameter name change I read about here: bisguzar/twitter-scraper#15

The request sent doesn't have the attribute 'core' Has anyone else had this issue? What version of requests should I have imported to use this library?

For Home Assistant there is an integration which uses coinmarketcap. In the past we were running into issues if a dependency was pinned to a specific release of one of their requirements.

coinmarketcap is pinning requests==2.18.4 and requests_cache==0.4.13. Could you please consider to ease this?

Thanks

I am attempting to use the API on python 2.7, but I have encountered an Unsupported Pickling Protocol: 3. I have done some research into pickle and have been unable to decipher how to correct the pickling protocol using pickle.dumps() and pickle.loads().

I installed the new version of it and every time when I try to get data I get metadeta and error dicts as well which make my work difficult. Just install the old version and everything is working smoother

I just installed via pip on windows, importing 'coinmarketcap' brings this error:

Traceback (most recent call last):

Any ideas ?

Hey again,

I'm wondering if you can help me, i'm trying to pull volume for each coin.
Out of 120 coins 15 don't work, i suspect it's because the coin names I have are different here's the pastebin for the coins that don't work: (i included DOGE as a control)
http://pastebin.com/uqawGyqw

I got the coin names from a scrapper on poloniex, so maybe some of them don't match, is there a way to use the coin symbol to acquire the coin name so i can replace all my existing coin names with the correct ones that agree with coinmarketcap's ?

Here's a copy of the spreadsheet im saving the data to:
new_values2.xlsx

Tremendous Thanks

Dave

Hi there,

I'm trying to scrape, on a daily basis, the summary for each coin using this function:
coinmarketcap.coin_summary('bitcoin')

However i'm struggling to find a way to get all the coin names. Do you happen to have a list ?

Kind Regards,

I need to search through currencies so here's what i do :
Let's say the user enters the word "bit", First i get the ids of the searched currency with listing endpoint, now i want to get list of those coins but there's no way to do this according to the documentation since ticker/{id} gives data only for 1 currency. is there any other way to do this?

So im calling

from coinmarketcap import Market
coinmarketcap = Market()
coinmarketcap.ticker(start=0, limit=3, convert='EUR')

as stated in the manual you provided and I have installed all the dependicies using PyCharm but every time I run it it just returns

Traceback (most recent call last):
File "C:/Users/J/PycharmProjects/Learning/coinmarketcap.py", line 1, in
from coinmarketcap import Market
File "C:\Users\J\PycharmProjects\Learning\coinmarketcap.py", line 1, in
from coinmarketcap import Market
ImportError: cannot import name 'Market'

I'm pretty new to python but have coded in the past in other languages im just not understanding what im doing wrong.
I have requests installed and requests cache installed i tried restarting PyCharm to see if maybe they werent registering but still to no avail. The module is installed in my Pycharm directory and the class Market() does exist im just not sure what im doing wrong...

Getting this error with version 4.0. Did not have any trouble with 3.0.1.
With 4.0 it says I need requests_cache. When I install requests_cache I get this error:
`

import coinmarketcap
coinmarketcap = coinmarketcap.Market()
stats = coinmarketcap.stats()
Traceback (most recent call last):
File "", line 1, in
File "/usr/local/lib/python2.7/dist-packages/coinmarketcap/core.py", line 64, in stats

File "/usr/local/lib/python2.7/dist-packages/coinmarketcap/core.py", line 34, in __request
response[0][u'cached'] = response_object.from_cache
KeyError: 0
`

Is there a way to use the data acquired from CoinMarketCap without creating an SQLITE File or any supplementary files?

Hello, I am under Debian8 and the answer is very long to come (about 1mn) ...

Hey ,

I want coin image url and graph url .can you please guide me how can I get the api..

Anyway I can get the altcoin prices on Bitcoins?

Im trying to install this onto my server through SSH and getting this error. Probably a newbie mistake as im just learning. I get this after trying to run the setup file after extraction

I have started to get this error when I do a pip install

I get this error when trying to call coinmarketcap. Despite a seemingly successful install using pip.

The wrapper seems to be working fine without one, but I don't want to get my IP rate limited. In the future I may have to purchase one of the paid api plans to avoid getting limited.

I have looked around and couldn't find where am I supposed to type my api key.

EDIT: I found out why, this wrapper is still using the public API v2. From coinexchange api documentation:

The Public API will be migrating to the new, more powerful Professional API on December 4th, 2018. Please update your application to use the free tier of the Professional API before then.

See #25.

Hi,

with API v2 the ticker request got a result limit of 100. Why? I would like to have one request for all currencies.

Best regards,

Moe

Hi,

I have been looking through the API and there seemed to have one missing data that I would really wish to have. Is it possible to expose the property value for each coin images in the API?

Thank you!

The current implementation stores cached data in a file called coinmarketcap_cache.sqlite in the current working directory. This is a little untidy. Given that the data is really only designed to be useful for a short period of time and it's unlikely that the user would ever want to interact with the cache file directly, would it make sense to save this file in a system temp directory instead?

I've implemented this here and would be happy to submit a pull request if it's something you would be interested in.

OS: Windows 10
Python: 3.5.2

This appears to actually be a problem with requests-cache, which has an open issue regarding just this problem. Just documenting it here as well in case anybody else encounters this. I can try to take a look at it a bit later.

I'm receiving the following error when trying to use the ticker method. I'm still able to access coinmarketcap.com regularly.

Exception: An error occured, please try again.

I am hitting rate limits. Unfortunately the library does not throw an according error, instead I get the following when trying to access the listing endpoint:

TypeError: 'JSONDecodeError' object is not subscriptable

I would suggest to propagate an error message here:

When I try for the first time using call 'coinmarketcap.ticker('VTC', limit=3, convert='USD')' I get the following error using python3. Note the cache file is actually created, but it is 0 size.

As simple as that ☝️

Seems the library is broken:

I wonder how easy is to request the top 10 of 24_change or other category like that, recursively.

I am getting the following bug:

  File "setup.py", line 16, in <module>
    long_description = file('README.md','r').read(),
NameError: name 'file' is not defined

When I use the ticker() method, instead of returning a list or dictionary, it returns a string. This is difficult to work with. Is the program supposed to do this?

I'm getting ModuleNotFoundError: No module named 'requests_cache' when trying to import coinmarketcap after a clean install from pip. Maybe requests-cache needs to be added to the dependencies?

import coinmarketcap as cmc

FOURTYTWO_PRICE = cmc.price('42')

Edit: Needed the dash. Sorry.

Wonder if this module has Python3 support and what to do to adjust.
Tried getting it in my python3 pip but got the issue of:

read(README)...

Instead I used open(README)... and worked. However the new issue is that when it tries to import the coinmarketcap_api and fails.

  File "/usr/local/lib/python3.4/dist-packages/coinmarketcap/__init__.py", line 19, in <module>

Hello all,

I am new to Github so not sure if this is the right way to raise an issue.

I am still beginner in python and would like to know how to run the coinmarketcap on python.

I have the Anaconda ... i typed: pip install marketcap --> successful installation --> what should be the next step ? how can i read the data or visualize it ? is it embedded in the code ?

Thanks
