Fastest free Kaia RPC, live no-key EVM endpoint latency
HTTP round-trip latency for the `eth_getBlockByNumber(\"latest\", false)` method against every free, no-key public Kaia EVM endpoint, audited every 60 seconds from 3 regions.
TL;DR. As of , Kaia Foundation leads rpc latency at 75 ms (p50, 24h) on Fastest free Kaia RPC, live no-key EVM endpoint latency. Source: OpenChainBench, https://openchainbench.com/benchmarks/kaia-rpc.

Kaia is the EVM L1 formed by the Klaytn + Finschia merger in Aug 2024, with Istanbul BFT consensus, KAIA gas token, and dominant footprint in Korea + Japan through LINE and Kakao integrations. Standard EVM JSON-RPC. Excluded: dRPC (500 paid plan only), BlockPI (`kaia.blockpi.network` returned `Apikey not found`), Nodies (`klaytn-pokt.nodies.app` requires paid subscription), Alchemy public (`KAIA_MAINNET not enabled for this app` on public tier), AllThatNode + OnFinality + Chainstack + Tatum + NowNodes (DNS-fail or key required). Every provider live-verified with 4 consecutive keyless probes at launch.
Methodology
Per-chain member of the RPC latency cluster, extended to Kaia. We measure the round-trip latency of a single, identical JSON-RPC call (`eth_getBlockByNumber(\"latest\", false)`) against the no-key public Kaia endpoint that sustains continuous probing (1 provider: Kaia Foundation official), every 60 seconds, from us-east, eu-west and Singapore. The harness classifies every response (ok / http_err / jsonrpc_err / stale / timeout) with a Kaia-scaled staleness gap (25 blocks at Kaia's ~1 s block time). The cross-chain view lives on the parent `rpc-capabilities` benchmark; this page is the Kaia-scoped answer with per-region breakdowns as a first-class dimension.
Frequently asked
What is the fastest free Kaia RPC right now?
Kaia Foundation currently leads at 75 ms (`eth_getBlockByNumber("latest", false)` p50 over the last 24h), measured against 1 no-key provider probed every 60 seconds from us-east, eu-west and Singapore. The leaderboard re-sorts continuously against fresh Prometheus samples. Use the region tabs to see the leader from the origin closest to your deployment.
Which Kaia RPCs work without an API key?
1 endpoint sustains continuous keyless probing: Kaia Foundation (public-en.node.kaia.io). dRPC was removed after returning 500 (paid plan only). See the methodology section for the specific endpoints that were audited and excluded.
Does the fastest Kaia RPC change by region?
Often. Public infra concentrates in specific regions; a gateway that wins from Amsterdam can lose from Singapore by multiples. The region tabs at the top of the page re-scope every number to a single origin; pick the one closest to where your requests originate.
How is Kaia RPC latency measured here, technically?
One identical `eth_getBlockByNumber("latest", false)` POST every 60 seconds against each provider from each of 3 regions, using the same plain HTTP client the rest of the RPC cluster uses. Wall-clock round-trip is recorded at millisecond precision; p50/p90/p99 are computed via Prometheus `quantile_over_time` over 24 hours. Responses are classified (`ok` / `http_err` / `jsonrpc_err` / `stale` / `timeout`) so an endpoint stuck on an old head or returning errors behind HTTP 200 is never ranked as fastest.
