Linea JSON-RPC API is one of 4 APIs that [Linea](https://apis.io/providers/linea/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include JSON-RPC, Ethereum, Blockchain, ERC-4337, and Account Abstraction. The published artifact set on APIs.io includes API documentation, an API reference, and a getting-started guide.

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.
