Create Location in Estimote Cloud by API

Is it possible to use the url Loading... provided in the estimote API for an indoor location?

I have this issue

{

"code": 402,

"title": "Indoor is not available in your subscription plan.",

"message": "Indoor is not available in your subscription plan. It seems you have registered more than 20 devices under your current Estimote Cloud Account. This account is free for under 20 devices in total (all types of beacons) and if you want to use our software for more beacons you would need to upgrade to a paid Software Subscription Plan. Please contact us at info@estimote.com and we will be more than happy to recommend the best fit for your planned usage, use-case and anticipated volumes."

}

I only have 4 beacons
