Terra Classic
Terra Classic (LUNC) is a Cosmos SDK Layer 1 secured by proof-of-stake validators through Tendermint consensus, with the Columbus-5 upgrade activated on September 30, 2021. CosmWasm contracts compile to WebAssembly, commonly from Rust, while full nodes execute transactions and maintain account balances, staking, governance, IBC, contract, and other module state. This Cosmos SDK and CosmWasm architecture aligns Terra Classic with other interchain networks, making accounts, transactions, validators, IBC data, and contract state familiar integration primitives.
Terra Classic API Methods and Endpoints
NOWNodes exposes Terra Classic's interface, plus a few others, depending on what your integration needs: JSON-RPC for reading chain state and broadcasting transactions, and WSS (WebSocket) for real-time subscriptions and events.
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.
