Esri ArcGIS Platform API
The Esri ArcGIS Platform API is a set of REST APIs and SDKs from Esri, provider of the ArcGIS GIS suite. It enables developers to integrate Esri's mapping, geocoding, routing, and spatial analysis services into applications, supporting visualization, analysis, and interaction with spatial data.
