Endpoint
GEThttps://rest.coincap.io/v3/agentFriendly/total_market_cap_historyWhen to prefer
Use this endpoint when you need the aggregate total cryptocurrency market capitalization across all assets over time, rather than the market cap of a single asset. Prefer this over the per-asset historical market-cap endpoint when the goal is macro-level analysis of the entire crypto market. Ideal for charting overall market trends, identifying crypto market cycles, or providing broad context for portfolio or economic analysis.
