It's invaluable for quant analysts, academics, DeFi developers, and data scientists who require precise, reliable pricing data for backtesting, AI training, analytics, or reporting.

How far back do most free crypto APIs go?

Coverage varies by provider, but most reputable free APIs offer multi-year daily data (often since the coin’s listing). For minute-by-minute or more granular data, APIs may only cover 1–3 years or limit retrieval to recent market history.

Which free API is best for large-scale backtesting?

For large-scale backtesting with broad asset coverage, CoinGecko and CryptoCompare are frequently used due to generous historical depth and asset support. For advanced research and AI-powered insight, Token Metrics provides unique on-chain and technical indicators alongside historical prices.

Are free API tiers reliable for commercial use?

While many free APIs have solid uptime and clean data, their terms often prohibit extensive commercial use or high-frequency access. For mission-critical or high-volume applications, consider paid plans for guaranteed support and uptime.

Can I get historic price data for niche coins or tokens?

Coverage for niche or newly launched coins varies significantly. Broad aggregators like CoinGecko and Token Metrics aim to provide data for a vast range of assets. However, for esoteric tokens, data may be limited to popular exchanges or more recent trading history.
