Nano API

degraded 4,302 Subscribers

Live on-chain data from the Nano network (XNO), a feeless, instant cryptocurrency with a block-lattice architecture where every account has its own blockchain and consensus is reached by Open Representative Voting (ORV): an account's confirmed XNO balance, receivable balance, block count and delegated representative; an account's own chain of blocks; a single block's amount, balance, height and confirmation; and the network's total, cemented and unchecked block counts plus the online voting weight securing it.

Chain Stats API

Live blockchain network statistics across 18 chains, from the public Blockchair feed. Get one network's full stats — price, market cap and dominance, block height, 24h transactions, circulating supply, difficulty, hashrate, mempool size and average fee; compare the major chains side by side, ranked by market cap; and read a chain's mempool congestion (pending transactions, size and fees). A multi-chain network-stats layer — distinct from single-coin price feeds and Bitcoin-only on-chain APIs: it answers how each blockchain is performing right now and how they compare. Live, with a 10-minute upstream cache.

Ravencoin On-Chain API

Live on-chain data from the Ravencoin (RVN) blockchain — a UTXO chain purpose-built for issuing and transferring digital assets and tokens, secured by the ASIC-resistant KAW-POW proof-of-work — via the public Trezor Blockbook explorer, clean JSON and no cache. Read the chain state (best block height, difficulty, sync status and node version); fetch a block by height or hash; look up an address's RVN balance, total received and sent and transaction count; or resolve a transaction's block, value, fee and confirmations. Read live from Ravencoin, nothing stored. This is Ravencoin's own KAW-POW asset-chain UTXO ledger — distinct from the Bitcoin, Dash, Decred, Nervos and other on-chain APIs and from price feeds: the RVN network built for tokenisation.

Dash On-Chain API

Live on-chain data from the Dash (DASH) blockchain — a payments-focused cryptocurrency — via the public Dash Insight explorer, clean JSON and no cache. Dash uses X11 proof-of-work plus a second tier of collateralised masternodes that power InstantSend (near-instant locked payments) and ChainLocks, and an on-chain treasury that funds proposals. Read the chain state (block height, difficulty, peer connections, protocol version and relay fee); fetch a block by height or hash; look up an address's DASH balance, total received and sent and transaction count; or resolve a transaction's block, value, fee, input/output counts and its InstantSend lock status. Read live from Dash, nothing stored. This is Dash's own X11, masternode-tier and InstantSend ledger — distinct from the Bitcoin, Decred, Ergo, Nervos and other on-chain APIs and from price feeds.

Conflux On-Chain API

Live on-chain data from the Conflux (CFX) network — a high-throughput Layer-1 that orders blocks with the Tree-Graph DAG consensus (not a single chain) and runs two spaces: the native Core space (cfx: addresses) and an EVM-compatible eSpace. Served live from a public Conflux Core-space JSON-RPC node as clean JSON. Conflux is distinctive for its storage-collateral model and a built-in proof-of-stake interest rate. Read the chain state (chain id, current epoch, block number, latest-finalized epoch, pending-tx count and the PoS interest rate); the supply (circulating, issued, staked and storage-collateral CFX); a block (the pivot block of an epoch) by epoch number or hash; or a Core-space address's CFX balance and staked balance. Read live from Conflux, nothing cached. This is Conflux's own Tree-Graph, storage-collateral and PoS layer — distinct from the Bitcoin, Decred, Ergo, Nervos and other on-chain APIs and from price feeds.
