Technical details
Endpoint
GEThttps://api.zerion.io/v1/fungibles/by-implementation/charts/max?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need the complete all-time price history (max period) for a specific fungible token identified by its on-chain contract address and chain. Prefer this over general market data APIs when you need DeFi-native, multi-chain token data anchored to a specific contract implementation rather than a ticker symbol, especially for long-tail or newer DeFi tokens not covered by centralised exchanges.
Side effects
- Missing required query params (chart_period or implementation) returns a 400 Bad Request
- Invalid or unsupported chain ID / contract address returns empty or 404 response
- Unsupported currency code may return an error or default to USD
- Rate limiting or payment failure (x402) returns 402 Payment Required
- Token not indexed by Zerion returns no chart data
