Endpoint for usage/cost data

I would like to request an endpoint for being able to track usage/costs

We adopt a multi provider strategy with different models used for different use cases. Our volume is high so it is important for us to be able to track usage in near real time and be able to intervene when needed.

The greater level of granularity the better but atleasst being able to fetch usage data by model would be a good start

Is there an api endpoint where we can access usage data? If not how do we submit and track feature requests?

Today we are able to track this on OpenAI, anthropic, google and aws bedrock.
