How throttling works
Limits are enforced at the edge. When request volume exceeds a configured cap, traffic is throttled for that window.
At a Glance
Gamma API
Public discovery endpoints with dedicated caps for events, markets, tags, and search.
General CLOB
5000 requests / 10s across general API traffic.
Market Data
High-throughput read limits for book, price, midpoint, and history routes.
Trading Writes
Dual-window enforcement for burst and sustained order/cancel traffic.

Subject to change
Treat these values as operational defaults. Production limits may be adjusted without a version bump. Gamma values mirror the published Polymarket Gamma guidance and should be treated as compatibility targets.
