SMS mailing service with a competent API?

Question

API

Good afternoon.
I shoveled the entire Runet in search of an SMS mailing service with a competent API. All clumsy to horror, it feels like they were written by schoolchildren.
I want:
0) json response
1) id for each message
2) sending personalized SMS to several numbers using a template in one request
3) the ability to check the cost before sending
4) checking the status by id
5) registering new customers with obtaining an access key
6) the ability to rollback from payments of my clients / developed affiliate program
7) the price is not more than 0.5 rubles. per sms
8) API not walking on crutches
