Count Entries in Array from Rest Api

Hi,

i hit kind of a dead end. I get a list of Scooters from the api and i want to count them and make the value available as a sensor.
Can i do this with the Restful Integration or do i have to make a script?

This is my Request

curl "https://platform.tier-services.io/v2/vehicle?lat=53.515562&lng=10.050908&radius=2000&&isRentable=true" -H "x-api-key: bpEUTJEBTf74oGRWxaIcW7aeZMzDDODe1yBoSxi2"

This is the Array

{"data":[{"type":"vehicle","id":"02eaa7c0-e6cc-4d07-9146-e73dc572b8fe","attributes":{"state":"ACTIVE","lastLocationUpdate":"2022-04-29T21:11:47Z","lastStateChange":"2022-04-28T10:19:36Z","batteryLevel":95,"currentRangeMeters":28000,"lat":53.516048,"lng":10.022059,"maxSpeed":20,"zoneId":"HAMBURG","code":296184,"iotVendor":"okai","licencePlate":"062WKR","isRentable":true,"vehicleType":"escooter","hasHelmetBox":false,"hasHelmet":false}},{"type":"vehicle","id":"f05d8076-281e-4526-b9a1-03494c1cea91","attributes":{"state":"ACTIVE","lastLocationUpdate":"2022-04-29T21:12:00Z","lastStateChange":"2022-04-25T20:40:25Z","batteryLevel":77,"currentRangeMeters":23000,"lat":53.531587,"lng":10.050504,"maxSpeed":20,"zoneId":"HAMBURG","code":142714,"iotVendor":"okai","licencePlate":"143WLG","isRentable":true,"vehicleType":"escooter","hasHelmetBox":false,"hasHelmet":false}},{"type":"vehicle","id":"b392f9ff-b07e-4e80-b8e6-ddeb2e0c90d6","attributes":{"state":"ACTIVE","lastLocationUpdate":"2022-04-29T21:08:47Z","lastStateChange":"2022-04-26T18:05:08Z","batteryLevel":89,"currentRangeMeters":27000,"lat":53.533199,"lng":10.050453,"maxSpeed":20,"zoneId":"HAMBURG","code":146188,"iotVendor":"okai","licencePlate":"328WLF","isRentable":true,"vehicleType":"escooter","hasHelmetBox":false,"hasHelmet":false}},{"type":"vehicle","id":"01963ef8-965d-441c-8752-47c9fd560f8f","attributes":{"state":"ACTIVE","lastLocationUpdate":"2022-04-29T21:15:32Z","lastStateChange":"2022-04-22T22:29:26Z","batteryLevel":28,"currentRangeMeters":8000,"lat":53.530502,"lng":10.039966,"maxSpeed":20,"zoneId":"HAMBURG","code":292527,"iotVendor":"okai","licencePlate":"727WLL","isRentable":true,"vehicleType":"escooter","hasHelmetBox":false,"hasHelmet":false}},{"type":"vehicle","id":"2e108137-2a1f-4184-9f78-7fa34ecdc61e","attributes":{"state":"ACTIVE","lastLocationUpdate":"2022-04-29T21:16:03Z","lastStateChange":"2022-04-28T03:21:13Z","batteryLevel":89,"currentRangeMeters":27000,"lat":53.532369,"lng":10.040975,"maxSpeed":20,"zoneId":"HAMBURG","code":184791,"iotVendor":"okai","licencePlate":"852WLG","isRentable":true,"vehicleType":"escooter","hasHelmetBox":false,"hasHelmet":false}},{"type":"vehicle","id":"9dc7330c-b7e5-411a-b6f1-33616ba116dd","attributes":{"state":"ACTIVE","lastLocationUpdate":"2022-04-29T21:09:55Z","lastStateChange":"2022-04-18T03:14:59Z","batteryLevel":34,"currentRangeMeters":10000,"lat":53.533193,"lng":10.050441,"maxSpeed":20,"zoneId":"HAMBURG","code":206342,"iotVendor":"okai","licencePlate":"546WLB","isRentable":true,"vehicleType":"escooter","hasHelmetBox":false,"hasHelmet":false}},{"type":"vehicle","id":"734d3184-2716-4c09-9c16-4716e15b666b","attributes":{"state":"ACTIVE","lastLocationUpdate":"2022-04-29T21:15:37Z","lastStateChange":"2022-04-29T20:53:53Z","batteryLevel":100,"currentRangeMeters":30000,"lat":53.532794,"lng":10.049542,"maxSpeed":20,"zoneId":"HAMBURG","code":187106,"iotVendor":"okai","licencePlate":"860WKR","isRentable":true,"vehicleType":"escooter","hasHelmetBox":false,"hasHelmet":false}}]}

so i want to take this array and count the scooter and display the total Number. Alternativly displaying them in a little map in the dashboard would be nice also.

Thanks for the help
