Per day we return the market count, summed liquidity, and a `contested_capital` weight = Σ liquidity·p·(1−p): p·(1−p) is the Bernoulli variance of a binary outcome, so this up-weights liquidity resting on genuinely uncertain (~50/50) markets and discounts near-decided ones. NOTE: `end_date` is the SCHEDULED close, not the actual resolution instant — markets can resolve early. Structural data only. ## Query parameters - `days` integer: Look-ahead window in days (max 60). - `min_volume` number: Minimum lifetime traded USD volume. - `include_decided` boolean: Include near-decided markets (drop the 0.05
