CoinMarketCap API
Industry-standard crypto data API with pricing, rankings, market cap, and global metrics for 10,000+ assets
Solid choice for most workflows
You need reliable, real-time crypto prices, market caps, and rankings for 10,000+ assets to power trading bots, dashboards, or portfolio trackers.
Highly accurate aggregated data from hundreds of exchanges; Basic is limited (no historical), paid unlocks depth but watch call credits and convert limits.
You want to backtest strategies or chart crypto trends without scraping unreliable sources.
Comprehensive since 2013 on top plans; lower tiers restrict history and conversions—plan upgrades for heavy use.
Tiered Data Access
Basic free plan lacks historical data and advanced endpoints; full features require paid plans starting at $29/mo.
API Call Credits
Each request consumes credits (1+ per call); exceed limits and get 429 errors—monitor usage dashboard and upgrade tiers to avoid throttling.
CoinMarketCap edges on brand trust and exchange aggregation depth; CoinGecko wins on free tier generosity.
When you prioritize industry-standard accuracy and are okay paying for pro features.
When you need more free historical data and simpler quotas.
