Scroll API

healthy 3,483 Subscribers

Real-time on-chain data for Scroll (chain-id 534352) — the native zkEVM layer-2 that scales Ethereum with zero-knowledge proofs. 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 ETH balance and transaction count of any address. A keyless, no-account JSON wrapper over the canonical Scroll JSON-RPC node — decoded from hex into plain decimals and human-readable ETH so you do not have to. Ideal for explorers, wallets, dashboards, gas estimators and analytics on the Scroll zkEVM rollup.

Zircuit API

Real-time on-chain data for Zircuit (chain-id 48900) — the zero-knowledge rollup layer-2 on Ethereum with AI-driven Sequencer Level Security. 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 ETH balance and transaction count of any address. A keyless, no-account JSON wrapper over the canonical Zircuit JSON-RPC node — decoded from hex into plain decimals and human-readable ETH so you do not have to. Ideal for explorers, wallets, dashboards, gas estimators and analytics on the Zircuit ZK rollup.

Linea Network API

Live on-chain data for Linea (chain-id 59144), a Consensys zkEVM Layer 2 that settles to Ethereum and uses ETH for gas. 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 ETH balance (in wei and whole ETH) 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, Layer-2 and Cosmos-chain APIs on the marketplace: this surfaces the Linea zkEVM network specifically.

Immutable zkEVM API

Live Immutable zkEVM on-chain data via Blockscout. Immutable zkEVM is a gaming-focused Ethereum L2; gas and balances are in IMX. Network stats, gas prices, latest blocks, a block by height or hash, address detail with IMX balance, a transaction by hash, ERC-20 token metadata and a universal search across addresses, tokens, blocks and transactions. Real data, no key.

World Chain API

Real-time on-chain data for World Chain (chain-id 480) — the Optimism-Superchain OP Stack layer-2 powering the Worldcoin / World ID ecosystem. 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 ETH balance and transaction count of any address. A keyless, no-account JSON wrapper over the canonical World Chain JSON-RPC node — decoded from hex into plain decimals and human-readable ETH so you do not have to. Ideal for explorers, wallets, dashboards, gas estimators and analytics on the Worldcoin chain.
