Internet Computer API

healthy 3,920 Subscribers

Live on-chain data from the Internet Computer (ICP), a blockchain that runs software as tamper-proof canisters on a network of independent subnets: the live network state (block height, running and stopped canisters, node count, number of subnets, message-execution rate), a ledger account's ICP balance and transaction count, a canister's type, controllers, name and subnet, and the subnets that shard the Internet Computer with their type, canisters, nodes and throughput.

Bitfinity API

Live Bitfinity on-chain data via Blockscout. Bitfinity is a Bitcoin- and Internet Computer-integrated EVM Layer 2; gas and balances are in BFT. Network stats, gas prices, latest blocks, a block by height or hash, address detail with BFT balance, a transaction by hash, ERC-20 token metadata and a universal search across addresses, tokens, blocks and transactions. Real data, no key.

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.
