About this API

Messari is a crypto research company founded 2018, positioning itself as "Bloomberg Terminal for crypto". Unlike CoinGecko/CMC which focus on market data, Messari focuses on fundamentals and research — per-asset team background, tokenomics (token economics including supply curves, unlock schedules, staking yields), on-chain metrics (active addresses, transaction volume, network fees), and quality research reports (Messari employs dozens of analysts). Messari API lets funds, research firms, and large crypto investors programmatically access this data. Free tier is limited (basic metrics only); Pro tier (from $30/month) unlocks deep data; Enterprise (thousands/month) includes API access + all research reports + custom research hours.
