The original title is "Litecoin RPC: Core JSON-RPC + Blockbook for Addresses and UTXOs"

Short summary

A developer guide to querying Litecoin using a two-API model: Litecoin Core JSON-RPC for blocks, transactions, and mempool, plus Blockbook REST for address balances, UTXOs, and xpub wallet views. Litecoin uses a UTXO model with no built-in address index in Core, so Blockbook handles address-based queries. Includes curl examples for common RPC methods and REST endpoints.

• •Litecoin Core JSON-RPC handles blocks, raw txs, mempool, and fee estimates
• •Blockbook REST provides address balances, UTXOs, and xpub wallet history
• •Client-side signing required — no server-side wallet; broadcast via sendrawtransaction
