Manifold API rate limits
As of September 15, 2026, Manifold warm book latency is 8.00 s at the median (p50, 24h window), with 9.60 s at p90 and 9.96 s at p99. Manifold ranks #5 of 5 chains measured on this benchmark.
Manifold documents 500 requests per minute per IP and explicitly welcomes bots on a single IP. The entire API is served behind max-age=5 plus stale-while-revalidate=10, so any client polling faster than every 6 seconds mostly reads cache; our probes space to 7 seconds and label residual cache hits. Manifold is an AMM, so the book class probes the bets feed, and lastUpdatedTime makes its data age verifiable. Warm p50: 8.00 s.
