Open Topo Data

The Open Topo Data API allows developers to add data sets with free terrain heights. The API provides REST architecture, JSON responses, and interpolation options, including closest, binary, and cubic. Locations are limited to 100 per request, and calls are limited to 100 per day. This API works as a free alternative to the Google Maps elevation API.
