Polymarket API latency

Polymarket's CLOB answers its midpoint endpoint at 200 ms p50 over warm connections (24h). The API fronts Cloudflare, so brief origin trouble often appears here as a latency spike before it ever becomes an error, which makes the latency series a useful early status signal. The uptime panel above is a live Polymarket API status check, computed from probes fired every 5 seconds from three regions, so it reacts within seconds of a real outage instead of waiting for user reports. For how the CLOB behaves under bursts, see the pm-rate-limits bench.
