Zilliqa (ZIL) API Documentation

Zilliqa

Zilliqa (ZIL) is a proof-of-stake Layer 1 using Pipelined Fast-HotStuff consensus since the Zilliqa 2.0 transition, replacing the network’s earlier proof-of-work-based validator selection. The network supports Scilla contracts and EVM-compatible Solidity execution against account-based state, while full nodes validate blocks and maintain accounts, contracts, storage, transactions, and validator state. This dual Scilla-and-EVM execution model gives applications access to native Zilliqa contract semantics while also preserving familiar Ethereum transaction formats and JSON-RPC conventions.

Zilliqa API Methods and Endpoints

NOWNodes exposes Zilliqa's interface, plus a few others, depending on what your integration needs: JSON-RPC for reading chain state and broadcasting transactions.

Browse the interfaces below for endpoint details, request parameters, response formats, and integration examples. Create an API key, select Mainnet or Testnet, choose the required interface, and start sending requests from your application.
