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.
Read Cardano transactions, addresses, balances, UTXOs, and block data through one REST API.
Subscribe to on-chain events — incoming and outgoing transactions, confirmations, and mined blocks.
Skip the infrastructure — managed, always-synced access with no node to operate or maintain.
Building a full wallet? Explore Wallet as a Service.
Need prices too? See the crypto price API, or run your own Cardano RPC nodes.
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.
