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\":\"status\",\"params\":[]}`. Plain HTTP POST, identical for every endpoint, no API key in any request. Non-cacheable by design: the rotating id defeats edge caches that would answer a bare status query 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 with a parsable decimal `sync_info.latest_block_height`), `http_err`, `jsonrpc_err` (HTTP 200 carrying an error body), `stale` (more than 40 blocks behind the cross-provider tip, roughly 4 minutes at Osmosis's ~6 s block time), `timeout`. Latency without reliability is a misleading ranking signal.","No archive-depth loop on this chain. Cosmos SDK chains access historical state via ABCI queries keyed on module + KV-store, which does not map onto the flat `eth_getBalance(address, height)` probe cleanly.","No cross-provider hash quorum on this chain at v1. Tendermint `status` does return `latest_block_hash` on the same block the height is reported for, so a quorum check is technically feasible, but the initial Osmosis add-on ships without it to keep the reliability change surface small; the hash normalisation across Cosmos chains will be validated before wiring bench 083 here.","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, cadence and exclusion rules apply on every chain.","Chain scope: every query on this page is pinned to `chain=\"osmosis\"`. Provider coverage at launch: 5 no-key endpoints (Osmosis Foundation, Polkachu, PublicNode, Imperator, LavenderFive).","Excluded by the launch audit: Lava (osmosis.tendermintrpc.lava.build 403 without a key despite public branding), OnFinality (osmosis public gateway timing out at probe cadence), Numia (401), AutoStake (404), BlockApsis / WhisperNode / Enigma-Validator / StakeTown / reece.sh (connect errors, likely IPv6-only or geo-gated), Ankr + Chainstack (paid Cosmos tiers only)."],"license":"CC-BY-4.0"}
