NEO
NEO (NEO) is a smart contract Layer 1 using delegated Byzantine Fault Tolerance, with the Neo N3 architecture combining NeoVM execution, native contracts, and on-chain governance. Contracts compile to NeoVM bytecode from supported languages including C# and Python, while full nodes execute transactions and maintain account, contract, storage, block, and native-asset state. This VM-centered model gives applications Neo-specific transactions and contract semantics while preserving a general RPC pattern for querying replicated chain state.
NEO API Methods and Endpoints
NOWNodes exposes NEO's interface, plus a few others, depending on what your integration needs: JSON-RPC for reading chain state and broadcasting transactions. Archive mode extends any of these to historical states and data beyond standard retention.
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.
