Covalent HQ

Covalent HQ is a unified API that allows you to use dozens of blockchain networks and billions of Web3 data points to retrieve balances, positions, and historical transaction data. With 100 billion transactions indexed, a two-block refresh time, and more than 200 thousand smart contracts available for querying, Covalent HQ has one of the richest and most extensive Blockchain data available today. 

One class of endpoints on Covalent HQ and Databar.ai are Class A endpoints (endpoints that return enriched blockchain data, which can be applied to all blockchain networks, such as balances and transactions). Using these endpoints on Databar.ai, one can retrieve an assortment of data, including address token balances. With just a given chain ID and wallet address, the current token balances and their spot prices are returned. Using other endpoints and the data they return, one can create investor dashboards to show price trends, liquidity, and ROI of assets. The Covalent API can also create taxation tools, which involve extracting historical balances and pricing the tokens provided on 26 blockchains, along with wallets and other use cases.
