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 to 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.","This page is part of the per-chain RPC cluster derived from the cross-chain [rpc-capabilities](/benchmarks/rpc-capabilities) benchmark; the identical harness, methodology and exclusion rules apply on every chain.
