description: 'Linea is ConsenSys'' ZK-EVM Layer 2 network built on Ethereum, offering
  low fees, fast finality, and full EVM compatibility. Developers access on-chain
  data through three complementary API surfaces: a public JSON-RPC endpoint (rpc.linea.build)
  supporting all standard Ethereum methods plus Linea-specific extensions (linea_estimateGas,
  linea_getProof), a REST Token API (token-api.linea.build) for ERC-20 token metadata
  and price history, and the Lineascan block explorer API (Etherscan V2-compatible)
  for transactions, blocks, addresses, token transfers, event logs, and contract verification
  across Linea Mainnet (chainId 59144) and Sepolia testnet (chainId 59141).'

  name: Linea JSON-RPC API
  description: Standard Ethereum JSON-RPC API plus Linea-specific extensions available
    at the public endpoint rpc.linea.build. Supports all eth_* methods (eth_blockNumber,
    eth_getBlockByNumber, eth_sendRawTransaction, eth_call, eth_getLogs, etc.) as
    well as ERC-4337 account abstraction bundler methods and Linea-specific methods
    including linea_estimateGas (returns baseFeePerGas, priorityFeePerGas, and gasLimit
    accounting for L1 verification costs) and linea_getProof. The public endpoint
    is free but rate-limited; production workloads should use a private node provider
    such as Infura or Alchemy.

  description: REST API for ERC-20 token data on the Linea network, available at token-api.linea.build.
    Provides token listings with filtering by security score, spam flags, and market
    metrics; token detail by contract address (name, symbol, decimals, current price,
    24h variation, total supply, FDV, swap counts); and hourly price history over
    the last 24 hours for one or multiple tokens. Rate-limited to 2 requests per second
    / 60 requests per minute per IP. No API key required for basic access.

  name: Linea Explorer API (Lineascan / Blockscout)
  description: Blockchain data APIs for Linea Mainnet backed by two explorer surfaces.
    The Lineascan (lineascan.build) explorer uses the Etherscan API V2 interface (chain
    ID 59144) with modules covering accounts (native and ERC-20/721/1155 balances
    and transfer histories), transactions (normal, internal, deposit, withdrawal),
    blocks (rewards, countdowns, block number by timestamp), smart contracts (source
    code, ABI, creator, verification), token information (supply, holder list, holder
    count), event logs (by address and topics), and network statistics (daily transaction
    counts, gas usage, new address counts, Ether price and supply). The Blockscout-based
    explorer (explorer.linea.build) provides a complementary REST and GraphQL API
    surface. An API key from lineascan.build is required; subscriptions are managed
    via the Etherscan API V2 portal.
