CHECKWIND.API v2 endpoints are now live. New features and enhancements include:
- Significantly reduced response time.
- Data is grouped by category (e.g. terrain, shielding, topography).
- View your request history for a specific day or month with the “/history” endpoint.
- Return Google’s elevation data to plot your own terrain profiles by adding
includeElevationData=trueto your request.
The legacy endpoints will continue to work side-by-side with the v2 endpoints for a transition period while existing customers migrate to the v2 endpoints, after which they will be removed.
Here’s an example response generated using the CHECKWIND.API v2 ASNZS1170 endpoint:
