# Litecoin Fees, Difficulty & Mining API > Litecoin's fee market, difficulty cycle and mining-pool distribution, live from the public Litecoin Space API (a mempool.space instance) — no key, nothing cached. The existing Litecoin reader covers addresses, transactions and blocks; this opens the network-economics layer it does not. Read the recommended fee rates in litoshi per virtual byte — from next-block down to economy and the relay minimum — together with the live mempool backlog. Read the difficulty adjustment: how far through the current 2016-block retarget window the chain is, the projected difficulty change, the estimated retarget date and the blocks remaining. And read the mining-pool distribution over the last week — which pools are finding Litecoin blocks, how many, their share and the network's estimated hashrate (Litecoin is mined with Scrypt, often merge-mined with Dogecoin). The fee-and-mining layer for Litecoin wallets, miners, fee estimators and analytics. Live from litecoinspace.org. ## Authentication All requests require your oanor API key in the `x-oanor-key` header.
