Headline p50/p90/p99 aggregate across all 3 regions via Prometheus `avg(quantile_over_time(...))`; per-region breakdowns are first-class on this page via the region tabs.","Payload: `{\"jsonrpc\":\"2.0\",\"id\":<rotating>,\"method\":\"eth_getBlockByNumber\",\"params\":[\"latest\",false]}`. Plain HTTP POST, identical for every endpoint, no API key in any request. Non-cacheable by design: the latest-header fetch with a rotating id defeats edge caches that answer eth_blockNumber without touching a node.","Latency: client-side round-trip delta in milliseconds, exposed as both a gauge and a histogram (buckets 50 ms → 10 s), so percentiles are computed via Prometheus `quantile_over_time` over the last 24 hours.","Call-result classification: `ok` (HTTP 200 + non-empty result), `http_err`, `jsonrpc_err` (HTTP 200 carrying an error body), `stale` (more than 20 blocks behind the cross-provider tip), `timeout`. Latency without reliability is a misleading ranking signal.","Archive depth: every 5 minutes we issue `eth_getBalance` at (head − depth) for depths from Geth's default pruned cap up to 5M blocks, exposing which free endpoints actually serve historical state.","This page is part of the per-chain RPC cluster derived from the cross-chain [rpc-capabilities](https://openchainbench.com/benchmarks/rpc-capabilities) benchmark; the identical harness, methodology and exclusion rules apply on every chain.","Chain scope: every query on this page is pinned to chain=\"bnb\". Provider coverage: 4 no-key endpoints (PublicNode, dRPC, Nodies, Binance). Blink (formerly Merkle) was delisted 2026-07: its gateway does not serve `eth_getBlockByNumber`, the anti-cache probe this cluster standardized on, so it cannot be measured on equal terms.
