Base vs MeowRPC

Latency is conditional on success: the harness times only calls returning a valid fresh block, so a mostly-failing endpoint can post a fast p50. Rows below 50 percent success are degraded; unresponsive probes pin below the table. The All chains aggregate favours single-chain foundation endpoints (Base, Binance, Arbitrum, Optimism, Avalanche officials) since they rank on one chain only; use a chain tab for honest comparison. Dead endpoints (cloudflare-eth POST returns -32603) are excluded.

A zero row means no incident was caught in the window, not a proof of correctness. Most providers post zero most days; this bench exists for the days they do not, and for the errors: a blocked eth_getLogs or a balance read gated behind a paid key at 40 blocks of depth counts as an incident because it is one from the caller's seat.
