Description

Karpet is a tiny library with just a few dependencies for fetching coins/tokens metrics data from the internet.

It can provide following data:

• coin/token historical price data (no limits)

• google trends for the given list of keywords (longer period than official API)

• twitter scraping for the given keywords (no limits)

• much more info about crypto coins/tokens (no rate limits)

What is upcoming?

• Reddit metrics

• Have a request? Open an issue ;)

Extras

Library uses a few nifty dependencies and is Python 3.6+ only. There is no need to install dependencies you don’t need. Therefore this library utilizes extras which install optional dependencies:

• for Google trends - google

Usage

1. Install the library via pip.

pip install karpet  # Basics only
pip install karpet[google]  # With Google trends

2. Import the library class first.

from karpet import Karpet

df = k.fetch_crypto_historical_data(id="ethereum")  # Dataframe with historical data.
df.head()

df.plot()
