Are there API platforms?

Question

PHP

Good afternoon.
For peace of mind, the wheel is not being reinvented.
Is there a platform / system / framework for monitoring and administering API with the ability to write business logic in php + java + C ++
What do you want from the platform:
1) Statistics - the number of calls to API methods, response time
2) Authentication - access to the panel authorization management/statistics, with shared access.
3) Limits and paid APIs - issuing API keys to users for making requests, with the ability to set limits on the number of requests, requests per second, and purchase premium keys for other limits.
4) Extensibility - with plugin support or open source.
It is not necessary to embed our business logic into the system itself; the option of proxying API requests through such a system is quite satisfactory. Those. the request comes to the system, the limits and access rights are checked, and when passing the checks, it is proxied to the API service itself.
Is there something that realizes Wishlist by 50% or more?
