The GoldRush Foundational API is a set of foundational multichain data APIs that offers structured responses for token balances, NFT assets, transactions, decoded log events, traces with internal transactions, state changes and input data. This API is ideal for applications that render wallet balances and activities, build NFT galleries, download historical transactions for cost-basis calculations among other use-cases. The API is offered via REST endpoints allowing developers to filter for specific chains and wallet addresses.
