  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.

    name: Linea Token API
    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.
