How to select a reliable data provider?
Coverage and freshness
Record counts and geographic coverage show how much data is available, which data freshness provides insight into it's usefulness. A massive dataset loses its value fast if it reflects a world from a year ago. Maintaining accuracy at scale requires years of infrastructure development, systematic refresh cycles, and the expertise to deliver real-time updates without sacrificing quality.
