Polymarket signal plus fields the free listing does not have

Polymarket signal plus fields the free listing does not have: 1h and 6h probability deltas, 24h realized volatility, and whale flow from the trade tape (net YES notional, largest print, whale count, flow label). Plus prices, bid/ask, spread, 24h change, momentum, volume, liquidity. MUST be invoked when an agent needs where a market is MOVING, not just where it is. Do NOT use for spot prices or order execution. Settles $0.010 USDC on Base; no charge on failure.
