Litecoin is a proof-of-work UTXO blockchain forked from Bitcoin in October 2011; it targets one block every 150 seconds using the Scrypt hashing algorithm. Litecoin exposes a Bitcoin-compatible JSON-RPC interface; the canonical height method is getblockcount. Public endpoints are available without an API key from Tatum (JSON-RPC gateway), BlockCypher (REST GET of its blockchain info endpoint) and LitecoinSpace (Esplora REST GET returning a plain block-height integer). Every provider was live-verified with consecutive block-height probes at launch.
Methodology
Per-chain member of the RPC latency cluster, extended to Litecoin. We measure the round-trip latency of a block-height query against every available public Litecoin endpoint that sustains continuous probing: 3 providers at launch, every 60 seconds, from us-east, eu-west and Singapore. Tatum is probed via JSON-RPC POST (getblockcount). BlockCypher is probed via REST GET of its blockchain info endpoint (height field). LitecoinSpace is probed via Esplora REST GET returning a plain block-height integer. The harness classifies every response (ok / http_err / jsonrpc_err / stale / timeout) with a Litecoin-scaled staleness gap (4 blocks, around 10 min at 150 s/block). The cross-chain view lives on the parent rpc-capabilities benchmark; this page is the Litecoin-scoped answer with per-region breakdowns as a first-class dimension.
Frequently asked
What is the fastest free Litecoin RPC right now?
LitecoinSpace currently leads at 172 ms (Litecoin block count p50 over the last 24h), measured against 3 providers probed every 60 seconds from us-east, eu-west and Singapore. The leaderboard re-sorts continuously against fresh Prometheus samples.
Which Litecoin RPC endpoints work without an API key?
3 endpoints sustain continuous keyless probing at launch: Tatum (litecoin-mainnet.gateway.tatum.io, JSON-RPC), BlockCypher (api.blockcypher.com/v1/ltc/main, REST GET) and LitecoinSpace (litecoinspace.org/api/blocks/tip/height, Esplora REST). Every listed endpoint was live-verified with a block-height probe returning a parsable result before inclusion.
Does the fastest Litecoin RPC change by region?
Often. Tatum and BlockCypher have fixed infrastructure so their latency rankings shift with geographic origin. The region tabs at the top of the page re-scope every number to a single origin.
How is Litecoin RPC latency measured here, technically?
One block-height probe every 60 seconds against each provider from each of 3 regions. Wall-clock round-trip is recorded at millisecond precision; p50/p90/p99 are computed via Prometheus quantile_over_time over 24 hours. Tatum uses JSON-RPC POST (getblockcount); BlockCypher uses REST GET (height field); LitecoinSpace uses Esplora REST GET returning a plain integer.
Why does LitecoinSpace return a plain integer instead of JSON?
LitecoinSpace is built on the Esplora block explorer API, which exposes the current tip height at /api/blocks/tip/height as a raw ASCII integer with no JSON envelope. This is the same format used by mempool.space for Bitcoin. The harness reads the body directly and parses it as a uint64.
