The Cross-Domain Synergies That Siloed APIs Cannot Deliver
When a category 4 hurricane strikes an LNG terminal or a major earthquake damages semiconductor fabrication plants, an agent querying only Polygon or Finnhub learns about the disruption hours later when equity prices crash. By correlating physical hazard sensors (USGS, NOAA) with shipping weather, power grid loads, and corporate filings on a single clock, pronto.stream enables proactive decision-making before market repricing completes.
