{"openapi":"3.1.0","info":{"title":"Moonriver API","version":"1.0.0","description":"Real-time on-chain data for Moonriver (chain-id 1285) — the Ethereum-compatible companion network to Moonbeam, deployed on Kusama, with MOVR as its native token. Query live network status (latest block height, network id, client version), fetch any block by height or the latest one (timestamp, transaction count, gas used / limit, base fee, miner), read the current gas price in wei and gwei, and look up the native MOVR balance and transaction count of any address. A keyless, no-account JSON wrapper over the canonical Moonriver JSON-RPC node — decoded from hex into plain decimals and human-readable MOVR so you do not have to. Ideal for explorers, wallets, dashboards, gas estimators and analytics on Moonriver.","contact":{"name":"PremiumApi","url":"https://www.oanor.com/by/premiumapi"}},"servers":[{"url":"https://api.oanor.com/moonriver-api","description":"oanor
