The CHECKWIND.API sandbox contains the list of available design APIs as both GET and POST requests. You must include both Revolutio and Google API keys in the request string (for GET requests) or the header (for POST requests) for the request to be successful.

How is CHECKWIND.API licenced?

CHECKWIND.API is licenced via monthly and yearly subscriptions. You pay for a specific number of request credits per month which are used each time to make a request. Only successful requests are counted towards your usage quota.

What are the requirements for the Google API key?

After creating a Google API key (it’s free), you must enable the Maps Elevation API and Geocoding API within the Google Cloud Console API Library.

How do I know if I have correctly enabled APIs within Google Cloud Console?

Enabled APIs will be listed at the bottom of the Google Cloud Console API Dashboard along with the current request totals. If you do not see the relevant API listed here, then it has not been enabled.

You can check that API key has not been restricted by clicking Credentials > [API Key Name]. If you do wish to restrict the API key, make sure that the Geocoding API and Maps Elevation API are selected.

Why is the terrain/exposure category detection not always totally accurate?

We’re dependent on the quality of Google Maps data for terrain/exposure category detection. Most new structures are built in or near urban areas where map data tends to be more accurate, and for this reason the detection algorithm is catered towards getting the best possible answers for urban sites.

Regional sites may have less refined map data, leading the detection algorithm to provide less accurate results. However, their isolation usually makes determining the terrain/exposure category straightforward by simply reviewing the satellite imagery.

My request is taking too long to complete or is returning an error.

Requests for very tall structures such as towers exceeding 50 m can take over 60 seconds to complete. Please make sure you set the timeout of your request to maximum of 230 seconds so the connection does not close before the request completes.

If you are still having trouble, you can make the request without the height (h) parameter, which will ignore terrain, shielding and exposure detection and focus solely on wind speed and topography. As such a request is independent of height, it should return within 5 seconds.
