0G Chain JSON-RPC is one of 9 APIs that [0G Labs](https://apis.io/providers/0g-labs/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Blockchain, EVM, Web3, JSON-RPC, and Crypto Infrastructure. The published artifact set on APIs.io includes API documentation.

Ethereum-compatible JSON-RPC endpoint for the 0G Chain mainnet ("Aristotle", chain ID 16661), an AI-focused Layer 1 with sub-second finality. Standard EVM methods (eth_chainId, eth_call, eth_sendRawTransaction, …) work unchanged with Hardhat, Foundry, Truffle, ethers.js and viem. Chain-specific surface is exposed through precompiles — DASigners at 0x…1000 for data-availability signer registration and quorum queries, and Wrapped0GBase at 0x…1001 for wrapping the native token as ERC-20 — plus staking and validator contract interfaces.
