Nano API

healthy 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.

Nano Representatives & Consensus API — oanor API marketplace

Nano Representatives & Consensus API

Nano's Open Representative Voting (ORV) consensus — the representative layer — live from the public Nano RPC, no key, nothing cached. Nano has no miners and no staking rewards: every account delegates its balance as voting weight to a representative, and online representatives vote to confirm transactions, with a quorum threshold securing the network. The base Nano reader covers accounts, blocks and history, but not the representative layer; this opens it. Rank the online representatives by delegated voting weight (in NANO), each with its share of total online stake and whether it clears the 0.1%-of-online-stake principal-representative threshold that earns a vote in consensus. Look up a single representative by address for its weight, stake share, principal status and whether it is currently online and voting. And read the live confirmation quorum — the total online voting stake, the trended and peer stake, the quorum delta and percentage, and the minimum weight a representative needs to count. The consensus-and-voting layer for Nano wallets, representative dashboards, delegators and analytics. Live from rpc.nano.to and peer nodes.

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.

DIA Decentralized Price Oracle API — oanor API marketplace

DIA Decentralized Price Oracle API

Live decentralized price-oracle data from DIA, with no key. DIA aggregates trade data across many CEXes and DEXes into transparent on-chain price feeds. Get a symbol quotation (current price, yesterday's price, 24h change and volume); an asset quotation by blockchain and contract address — the same multi-chain oracle feed smart contracts consume; the catalogue of quoted assets with their chain, address and volume; and the list of supported symbols. Distinct from CEX tickers and CoinGecko-style aggregators: these are oracle reference prices across 949 symbols and 5,500+ assets.
