Alternatives to block.io api or blockchain.info api?

Question

API

Hello. I know that such questions have already been asked, but nevertheless, I didn’t find detailed answers anywhere or didn’t search well.
The task is simple, for each registered user a unique wallet is generated to which he can send a cue ball, the cue ball came, was displayed in the account.
Now I have implemented this using the block.io api, but the service is not credible, of course it will work for tests, but it is not very interesting for serious projects, you need to make an api request with blockchain.info ..
How do you implement such things?
