Aptos RPC endpoints: free public URLs by latency
HTTP round-trip latency for the Aptos REST ledger endpoint (block_height) against every free, no-key public Aptos node, audited every 60 seconds from 3 regions.
TL;DR. As of , Aptos Labs has the lowest median latency of the 2 free public Aptos RPC endpoints measured, 42 ms (p50, 24h, 3 regions). Source: OpenChainBench, https://openchainbench.com/benchmarks/aptos-rpc. 2 public endpoints, no key: api.mainnet.aptoslabs.com, fullnode.mainnet.aptoslabs.com. Full URLs with their 24h median are listed below.

Aptos is a Move-based L1 blockchain targeting over 100,000 TPS via Block-STM parallel execution, producing roughly one block per second with sub-second finality. Unlike EVM chains, Aptos exposes a REST API rather than JSON-RPC: GET /v1/ returns the current ledger block_height as a decimal string. Free public API endpoints are available without a key from Aptos Labs (2 endpoints). Every provider was live-verified with consecutive keyless GET /v1/ probes at launch.
Methodology
Aptos: 2 free public RPC endpoints answering HTTP GET /v1/ every 60 seconds from us-east, eu-west and Singapore, ranked by 24h median. Aptos Labs (tied) leads at 42 ms. We measure the round-trip latency of a single REST GET to /v1/ against every no-key public Aptos node that sustains continuous probing: 2 providers live today, every 60 seconds, from us-east, eu-west and Singapore. The harness classifies every response (ok / http_err / stale / timeout) with an Aptos-scaled staleness gap (300 blocks, around 5 min). The cross-chain view lives on the parent rpc-capabilities benchmark; this page is the Aptos-scoped answer with per-region breakdowns as a first-class dimension.

Frequently asked
Which Aptos nodes work without an API key?
2 endpoints are probed on this chain, each listed with its URL, 24h median and success rate in the endpoints table on this page. Every listed endpoint was live-verified with a GET /v1/ returning a parsable block_height before inclusion.
