Demand-to-supply matching — unmet agent demand crossed against who already sells it. Each row pairs something agents ask for and cannot get with the number of origins already selling in that category, so you can tell a genuine product gap from a distribution problem. A lead list if you already sell there; a build order if nobody does. HOW TO CALL: GET /api/demand/matches?days=7&limit=25 PARAMETERS: days — lookback window, 1-90 (default 7) limit — rows returned, 1-100 (default 25) RESPONSE: matches[] with the wanted path, request volume, bucketed asker count, existing supplier count, field median price, and a verdict. PRICING: $0.10 per call.
