Kalshi API - Arbiter

These endpoints return raw Kalshi data directly from the Kalshi API without normalization. Use them when you need platform-specific fields that the unified API strips out.

Cross-platform dashboards, analytics	Unified API (`/v1/markets`)
Kalshi trading bots	Native API (`/v1/kalshi/markets`)
