  title: Litecoin Core JSON-RPC Addresses API
  description: 'The primary programmatic interface to a Litecoin Core node. Clients send HTTP POST requests with JSON-RPC 2.0 payloads to interact with the node. Methods cover blockchain state, block and transaction retrieval, mempool inspection, network peers, mining, UTXO queries, address validation, raw transaction construction and broadcast, and fee estimation. Authentication is required via cookie file or rpcauth credentials. The daemon listens on port 9332 (mainnet), 19332 (testnet), and 19443 (regtest).
