Read public market data from Deribit's REST API — instruments, ticker, order book, index price, funding rate, historical DVOL — no auth required. Use this skill whenever the user asks for Deribit data on BTC, ETH, SOL, or any other Deribit currency, including option instruments, perpetual funding, dated futures basis, or the volatility index. Triggers: "Deribit", "BTC options", "ETH options", "BTC funding rate", "perpetual basis", "DVOL", "Deribit ticker", "options chain on Deribit", "BTC-PERPETUAL", "BTC-25DEC25-100000-C". Activate even with partial input — default currency = BTC, default kind = option.
