Flow (Cadence) On-Chain API
The Flow blockchain's native Cadence layer, live from the official public Flow access REST API — no key, nothing cached. Flow runs two environments: an EVM layer and its own resource-oriented Cadence environment. The existing Flow reader covers the EVM side; this opens the Cadence layer it cannot see. Read a Cadence block by height — or the latest sealed block — with its id, parent block, timestamp and the number of collection guarantees and seals it carries. Look up any Cadence account for its FLOW balance, the number of account keys it holds and the Cadence smart contracts deployed under it. And read the live network status: the chain id, the access-node software version, the current spork id, the protocol state version and the compatible block-height range. The Cadence-on-chain layer for Flow wallets, explorers, dapp builders and analytics. Live from rest-mainnet.onflow.org.
