The Cardano API — build without running a node

Access Cardano blockchain data through one unified REST API: transaction and address data, balances, block data, and real-time webhooks for on-chain events — with no Cardano node to run and maintain. Start free and scale as you grow.

ADA - the fuel of Cardano

Cardano's native cryptocurrency, ADA, facilitates the internal transactions between peers and can also be staked in the Cardano network. Holders of the coins can delegate them to a stake pool to maintain the successful running of the network and earn rewards.
