## When to prefer this

Use this endpoint when you need on-chain Ethereum validator tip/priority fee time-series data sourced from Glassnode, especially for analyzing supplementary validator income trends, EIP-1559 fee dynamics, or comparing tip levels over different time horizons. Prefer over generic fee endpoints when you specifically need tips separated from base fees.
