# Monitor Cryptocurrency Market Cap

Market cap is the simplest measure of a cryptocurrency's scale. It tells you how big a project is relative to its peers, and shifts in market cap rankings signal major changes in market sentiment. When a token climbs the rankings, capital is flowing in; when it drops, attention is moving elsewhere.

The market_data skill provides market cap figures alongside other key metrics. Agents can pull rankings, compare tokens by market cap, and track dominance percentages. This gives you a bird's-eye view of the crypto market -- which sectors are growing, which tokens are gaining ground, and where the money is moving.
