Quick Start

pip install cryptodatapy

from cryptodatapy import DataRequest

# Get Bitcoin daily prices from multiple sources
dr = DataRequest(
    tickers=['BTC', 'ETH', 'SPA'],
    fields=['close', 'volume', 'market_cap'],
    freq='daily',
    start_date='2024-01-01'
)

data = dr.fetch()
print(data.head())

Data Types

Price Data

# OHLCV data
dr = DataRequest(
    tickers=['SPA', 'ETH'],
    fields=['open', 'high', 'low', 'close', 'volume'],
    freq='1h',
    source='binance'
)

On-Chain Metrics

# Active addresses, transaction count, hash rate
dr = DataRequest(
    tickers=['ETH'],
    fields=['active_addresses', 'tx_count', 'hash_rate'],
    freq='daily',
    source='glassnode'
)

DeFi Metrics

# TVL, yields, protocol revenue
dr = DataRequest(
    tickers=['sperax', 'aave', 'uniswap'],
    fields=['tvl', 'revenue', 'fees'],
    freq='daily',
    source='defillama'
)

Social Data

# Social volume, sentiment, developer activity
dr = DataRequest(
    tickers=['SPA', 'BTC'],
    fields=['social_volume', 'dev_activity', 'github_stars'],
    freq='daily',
    source='santiment'
)

Derivatives

# Open interest, funding rates, liquidations
dr = DataRequest(
    tickers=['BTC', 'ETH'],
    fields=['open_interest', 'funding_rate', 'liquidations'],
    freq='1h',
    source='coinglass'
)

Multi-Source Aggregation

# Fetch from multiple sources and merge
dr = DataRequest(
    tickers=['SPA'],
    fields=['close', 'volume', 'tvl', 'social_volume'],
    sources=['coingecko', 'defillama', 'santiment'],
    freq='daily',
    agg_method='first_valid'  # Use first non-null value
)

Output Formats

# Pandas DataFrame (default)
df = dr.fetch()

# JSON
json_data = dr.fetch(format='json')

# CSV export
dr.fetch().to_csv('crypto_data.csv')

# Parquet (efficient storage)
dr.fetch().to_parquet('crypto_data.parquet')

Use Cases

Portfolio Tracking

portfolio = ['SPA', 'ETH', 'BTC', 'USDC']
dr = DataRequest(
    tickers=portfolio,
    fields=['close', 'market_cap', 'volume'],
    freq='daily',
    start_date='2024-01-01'
)
data = dr.fetch()
returns = data['close'].pct_change()

Sperax Analytics

# Track USDs supply and SPA metrics
dr = DataRequest(
    tickers=['SPA'],
    fields=['close', 'volume', 'market_cap', 'tvl'],
    sources=['coingecko', 'defillama'],
    freq='daily'
)

Backtesting Data

# Get clean historical data for backtesting
dr = DataRequest(
    tickers=['ETH', 'BTC'],
    fields=['open', 'high', 'low', 'close', 'volume'],
    freq='1h',
    start_date='2023-01-01',
    end_date='2024-12-31',
    source='binance',
    fill_method='ffill'  # Forward fill gaps
)
