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.

Internet Computer NNS Governance API — oanor API marketplace

Internet Computer NNS Governance API

Internet Computer NNS (Network Nervous System) governance, live from the official public dashboard API — no key, nothing cached. The NNS is the on-chain DAO that controls the entire Internet Computer: ICP holders lock tokens into neurons and vote on proposals across topics — protocol upgrades, network economics, node administration, canister management, SNS launches and more. The base Internet Computer reader covers network, accounts, canisters and subnets, but not governance; this opens it. List NNS proposals filtered by topic and status, each with its title, proposer neuron, voting deadline and yes / no voting-power tally with percentages. Read a single proposal in full — its tally, action, status and decision timestamps. And get a live governance overview: the all-time total proposal count, how many are currently open for voting, and the breakdown of recent proposals by topic and status. The on-chain governance layer for Internet Computer wallets, neuron dashboards, voters and analytics. Live from ic-api.internetcomputer.org.

Bitfinity API — oanor API marketplace

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.

Sonic Network API — oanor API marketplace

Sonic Network API

Live on-chain data for Sonic (chain-id 146), a high-performance EVM-compatible Layer 1 (the network formerly known as Fantom) with the S gas token. Read the chain status — chain id, latest block number, current gas price, node client version and sync state — fetch any block by number (or the latest) with its hash, parent hash, timestamp, transaction count, gas used and limit, base fee and proposer, read the current gas price and max priority fee in both wei and gwei, and look up any account address for its S balance (in wei and whole S) and transaction nonce. Addresses use the standard 0x EVM hex form. A short protective cache keeps responses fast while staying within a few seconds of the chain. Distinct from other Layer-1, Cosmos and Move-chain APIs on the marketplace: this surfaces the Sonic EVM network specifically.

Blockchair Multi-Chain Stats API — oanor API marketplace

Blockchair Multi-Chain Stats API

Live on-chain network statistics, mempool conditions and market data across the major UTXO blockchains and Ethereum, sourced from Blockchair. For any supported chain read the full network state — best block height, total and 24-hour block and transaction counts, mining difficulty, hashrate, coin circulation, on-chain transfer volume and chain size — or zoom into the mempool to see pending transactions, mempool size, transactions-per-second, the suggested fee per byte (or median gas price on Ethereum) and average and median transaction fees in native units and USD, or pull market data with the coin price in USD and BTC, 24-hour change, market capitalisation and dominance. Ten chains are covered: Bitcoin, Bitcoin Cash, Litecoin, Dogecoin, Dash, Zcash, Bitcoin SV, eCash, Groestlcoin and Ethereum. Distinct from single-chain mempool and gas feeds: this is one consistent multi-chain stats surface.
