Open Topo Data — Batch Elevation Query

Get land surface elevation for up to 100 lat/lon coordinates in a single request. All points share the same dataset (srtm90m default, srtm30m, or aster30m). Returns an array of results, each with elevation_m, lat, lon, and dataset. Ideal for elevation profiling along a route, contour-line computation, or bulk terrain analysis. MIT licence, no auth, no upstream cost.
