About this API
CryptoCompare is a London-based crypto data aggregation platform founded in 2014, positioning itself as "data depth more professional than CoinGecko/CMC". Strongest in historical data — some coins go back to early 2010s (2-3 years earlier than CoinGecko), invaluable for quant research and backtesting. Also provides data uncommon elsewhere: social media sentiment (Twitter, Reddit mentions and sentiment), crypto news aggregation (real-time scraping of mainstream crypto media), wallet comparison, ICO historical data, etc. Free tier 100k calls/month is very generous for personal projects and small apps. Commercial from $99/month. Holds a niche in professional quant crypto research.
