How this service works
Paid API endpoints for prices, weather, FX, news, gas, dominance, fear/greed, ATH, and more
Output
Returns Bitcoin's current dominance as a percentage of total crypto market capitalization (e.g. 52.4%). The format parameter can adjust the response format, defaulting to percent. Response is a lightweight JSON payload with the current dominance value.
Example use cases
Crypto portfolio rebalancing trigger
“Check Bitcoin's current market dominance percentage — if it's above 55% I want to shift more of my portfolio into BTC.”
Altcoin season detection
“What's BTC dominance sitting at right now? I'm trying to figure out if we're in altcoin season or if Bitcoin is still taking the lion's share of the market.”
Trading strategy dashboard widget
“Pull the latest Bitcoin dominance figure for my market dashboard — I need it as a percentage so I can track the trend over time.”

Choose this endpoint when you need a quick, low-cost ($0.01 USDC) real-time Bitcoin dominance figure without requiring a full exchange API integration or CoinMarketCap/CoinGecko account. Ideal for lightweight agents that need a single dominance datapoint for trading signals, dashboards, or market condition checks. The x402 micropayment model makes it suitable for pay-per-call agent workflows.
