How this service works
Interpreted wallet data for more than 40 chains and Solana: portfolios, DeFi positions, PnL, transactions and NFTs. REST for apps, x402 pay-per-call for agents.
Output
Returns a JSON object with a data field containing the token's resource ID, type, and attributes including price chart data points over the requested period, plus self and pagination links. The attributes follow the Zerion API resource schema documented at developers.zerion.io.
Example use cases

Technical details
Endpoint
GEThttps://api.zerion.io/v1/fungibles/by-implementation/charts/%7Bchart_period%7D?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need historical price chart data for a specific token identified by its on-chain contract/implementation address and chain ID, particularly across 40+ EVM chains and Solana. Prefer this over generic market data APIs when you need multi-chain DeFi token coverage or are already working within the Zerion ecosystem for wallet/portfolio data. Best when the token's implementation address is known rather than just its symbol.
