KCC Chain API

healthy 4,926 Subscribers

Live on-chain data for KuCoin Community Chain (KCC) — an EVM Layer 1 backed by the KuCoin community — via its public Blockscout explorer (no wallet, no key). The stats endpoint returns chain-wide totals (blocks, transactions, addresses, average block time, gas used); gas gives the current gas-price oracle (slow/average/fast). Blocks lists the latest blocks, and a single block resolves by height or by hash with its transaction count, gas, validator and timestamp. The address endpoint returns any account's KCS balance, nonce, contract flag and token holdings; transaction resolves a tx by hash with its from/to, value in KCS, fee, status and block. The token endpoint returns an ERC-20 token's metadata (name, symbol, decimals, total supply, holders) by contract address, and search runs a universal lookup across addresses, tokens, blocks and transactions. Gas, balances, values and fees are denominated in KCS, the native coin. Real on-chain data straight from the explorer, refreshed every call — no key. 9 endpoints. For multi-chain coverage combine with the other oanor chain APIs (Ethereum, Base, Arbitrum and more).

KuCoin API — oanor API marketplace

KuCoin API

Live spot-market data from KuCoin, one of the largest crypto exchanges and the best-known venue for altcoins, via its public API. KuCoin lists over a thousand trading pairs, so its signature is breadth. Get a pair's full 24-hour snapshot: last price, best bid and ask, high, low, the 24-hour change in price and percent, the base and quote volume, the 24-hour average price and the taker and maker fee. Pull the entire board — every KuCoin pair in one call with its last price and 24-hour change. Get the top of the order book with the spread. Read OHLCV candles at any interval. Live, no key, nothing stored. Distinct from Coinbase, Bitstamp, OKX, Gate.io, Bitfinex, Gemini, Kraken and Bybit venue APIs and from aggregated feeds — this is KuCoin's own ticker, full pair board, order book and candles. Perfect for trading, charting and market-data apps.

 Meter API — oanor API marketplace

Meter API

Live EVM on-chain data for Meter (chain id 82) — the HotStuff-BFT proof-of-stake Layer-1 whose native gas token is MTR — served directly from public EVM JSON-RPC nodes with multi-node failover. The status endpoint returns the chain and network id, the latest block height and the node client version. The block endpoint returns a block by number (or the latest) with its hash, parent hash, timestamp, transaction count, gas used and gas limit, miner and size. The gas endpoint returns the current gas price in both wei and gwei. The balance endpoint returns the MTR balance and outgoing transaction count for any address, converted from base wei (18 decimals) into whole MTR with exact big-integer scaling. Every figure is read live from the chain over JSON-RPC — nothing bundled or modelled — behind a short server-side cache with keep-warm so the feed stays fast and fresh. Ideal for explorers, wallet and dashboard tooling, gas trackers, address monitors and analytics apps across the Meter ecosystem. Live keyless upstream. 5 endpoints.

 Songbird API — oanor API marketplace

Songbird API

Live EVM on-chain data for Songbird (chain id 19) — the canary network of the Flare blockchain, whose native token is SGB — served directly from public C-chain JSON-RPC nodes with multi-node failover. The status endpoint returns the chain and network id, the latest block height and the node client version. The block endpoint returns a block by number (or the latest) with its hash, parent hash, timestamp, transaction count, gas used and gas limit, miner and size. The gas endpoint returns the current gas price in both wei and gwei. The balance endpoint returns the SGB balance and outgoing transaction count for any address, converted from base wei (18 decimals) into whole SGB with exact big-integer scaling. Every figure is read live from the chain over JSON-RPC — nothing bundled or modelled — behind a short server-side cache with keep-warm so the feed stays fast and fresh. Ideal for explorers, wallet and dashboard tooling, gas trackers, address monitors and analytics apps across the Flare and Songbird ecosystem. Live keyless upstream. 5 endpoints.

 Sophon Chain API — oanor API marketplace

Sophon Chain API

Real-time on-chain data for Sophon (chain-id 50104), a ZK Layer-2 built on the zkSync Elastic Chain stack and focused on consumer and entertainment apps, where gas is paid in the native SOPH token. The status endpoint returns the chain id, network id, latest block height, native symbol and node client version so you can confirm the chain is live and synced. The block endpoint returns a block by decimal or 0x-hex height — or the latest block when no height is given — with its hash, parent hash, timestamp (raw and ISO), transaction count, gas used and limit, base fee and miner. The gas endpoint returns the current gas price in both wei and gwei at the latest block. The balance endpoint returns the native SOPH balance (in wei and human-readable units) and the transaction count (nonce) for any 0x address. The meta endpoint documents the chain id, decimals and ecosystem. Reads a live Sophon JSON-RPC node directly, so values are current to the latest block. Live, nothing stored. 5 endpoints. This serves native-coin and chain data; for ERC-20 token balances or contract calls use a dedicated token/contract API.
