Use this endpoint when you need the live on-chain USD price for the specific Base network token at 0x00dde4d2f08497bcec6f5e0666f63e14b3a1dab9, sourced directly from DEX liquidity data via CoinGecko's on-chain API. Prefer this over CoinGecko's standard simple/price endpoint when you need DEX-sourced pricing rather than aggregated CEX/CoinGecko index prices, or when working specifically with tokens on the Base L2 network that may not have a CoinGecko coin ID.
