Do Anthropic quotas give you precise remaining token counts or something? I have something similar set up for tracking my ChatGPT usage but it only gives percentages remaining, which is a pretty coarse metric.

Claude code supposedly has otel you can set via env. I haven't set it up, so I'm just repeating hearsay.. but it supposedly has everything relevant in it wrt token usage and cost

It's meant for their test env I think, so is not documented to my knowledge
