Technical details
Endpoint
GEThttps://api.web3identity.com/api/bitcoin/marketcapWhen to prefer
Use this endpoint when you need Bitcoin-specific market capitalization and dominance metrics rather than general token prices. Ideal for dashboards, portfolio tools, or macro crypto market analysis where BTC dominance and rank are required data points. Prefer this over generic token price endpoints when dominance and circulating supply are needed.
