Tezos RPC endpoints: free public URLs by latency
HTTP round-trip latency for GET /chains/main/blocks/head/header against every available public Tezos node, audited every 60 seconds from 3 regions.
TL;DR. As of , TezBeta has the lowest median latency of the 4 free public Tezos RPC endpoints measured, 91 ms (p50, 24h, 3 regions). Source: OpenChainBench, https://openchainbench.com/benchmarks/tezos-rpc. 4 public endpoints, no key: rpc.tzbeta.net, mainnet.smartpy.io, rpc.tzkt.io, prod.tcinfra.net. Full URLs with their 24h median are listed below.

Tezos is a self-amending proof-of-stake blockchain using Liquid Proof of Stake (LPoS) and an on-chain governance mechanism that allows protocol upgrades without hard forks. It targets roughly one block every 30 seconds on mainnet. Public REST endpoints are available without an API key from SmartPy, TezBeta, TzKT (Baking Bad) and TCInfra. Every provider was live-verified with consecutive block header probes at launch.
Methodology
Tezos: 4 free public RPC endpoints answering `GET /chains/main/blocks/head/header` every 60 seconds from us-east, eu-west and Singapore, ranked by 24h median. TezBeta leads at 91 ms. We measure the round-trip latency of a single REST call (GET /chains/main/blocks/head/header) against every available public Tezos node that sustains continuous probing: 4 providers live today, every 60 seconds, from us-east, eu-west and Singapore. The harness classifies every response (ok / http_err / jsonrpc_err / stale / timeout) with a Tezos-scaled staleness gap (10 blocks, around 5 min at 30 s/block). The cross-chain view lives on the parent rpc-capabilities benchmark; this page is the Tezos-scoped answer with per-region breakdowns as a first-class dimension.

Frequently asked
Which Tezos RPC endpoints work without an API key?
4 endpoints are probed on this chain: SmartPy (mainnet.smartpy.io), TezBeta (rpc.tzbeta.net), TzKT by Baking Bad (rpc.tzkt.io/mainnet) and TCInfra (prod.tcinfra.net/rpc/mainnet). Every listed endpoint was live-verified with a block header call returning a parsable level before inclusion.
