Prediction-marketsMarket-dataPolymarketKalshiPagination

Serves the in-memory Polymarket+Kalshi market universe (worker-refreshed ~60s; up to 5 min stale before the gate 503s). Filters and sorts the WHOLE cached universe by volume_24h, then slices: limit trims output, not work. Zero DB and zero upstream calls in the request path. Empty pages (filters matching nothing, cursor past end) return 200 and are billable.
