Technical details
Endpoint
GEThttps://api.zerion.io/v1/fungibles/eth/charts/day?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need historical price chart data for a specific fungible token (like ETH) over a defined time window from Zerion's DeFi-native data source. Prefer this over generic crypto price APIs when you need data that integrates seamlessly with Zerion's broader DeFi portfolio and wallet context, or when building agents that already use Zerion for wallet and position data.
