What are the stable analogues of blockchain without a limit on the number of requests to api?

Question

PHP

Since the blockchain has been behaving very strange lately, I am looking for a replacement for it, with a stable service that provides api for working with a bitcoin wallet.
It is desirable without restrictions on the number of requests to api, btc addresses per account and a low commission.
Support for other cryptocurrencies is also welcome.
At the moment I'm looking towards coinbase.com
