Healthcare market mapping increasingly depends on granular, up‑to‑date data on provider networks and drug formularies. Payers, health systems, digital health companies, and analytics firms use these data to understand network adequacy, competitive positioning, product design, and patient access. However, much of this information is not available via clean, official APIs; instead, it resides in heterogeneous, JavaScript-heavy web portals that were built for human browsing, not machine consumption.
