Manifold API latency

As of July 31, 2026, Manifold API latency (price endpoint) is 325 ms at the median (p50, 24h window), with 385 ms at p90 and 399 ms at p99. Manifold ranks #4 of 5 chains measured on this benchmark.

Manifold's API sits entirely behind a CDN cache (max-age=5 plus stale-while-revalidate=10), which complicates both latency and status measurement: a cached 200 can mask a struggling origin for a few seconds. Our probes space to 7 seconds, label every residual cache hit, and the 325 ms p50 shown here counts origin responses only. For uptime this cuts the other way, the cache absorbs brief origin blips, so Manifold's measured availability is high and its real failure mode is stale data rather than errors.
