🟡 Totals mirror the cached Forkast balances, so extremely new markets may take a sync or two to appear.
Call https://data-api.forka.st/oi to retrieve the notional value locked in each market. Without filters the endpoint returns every cached market; include a market CSV query to narrow the scope. This route is ideal for surfacing liquidity indicators alongside price feeds or for alerting systems that watch for sudden drops in interest.
