Current price of cryptocurrencies by CoinGecko id (bitcoin, ethereum, solana, ...) in one or more fiat currencies, with 24h change, market cap and volume. CoinGecko's free API is tightly limited, so this is capped at about 10 fresh lookups a minute service-wide and cached for 2 minutes.
Name on the gateway: knowledge__crypto_price · read-only.
