Your goal: price one request
- Open Calculator and choose Plan usage.
- Add a model, then explicitly select its provider endpoint and service tier.
- Enter total native input and billed output tokens. Output includes hidden reasoning. Set Identical requests to 1.
- Calculate, then expand Show calculation to see each quantity, rate and amount.
If you do not know the counts, obtain the client's final native usage record. Word counts and effort labels do not supply them. Missing evidence stays unavailable, not zero. A projection does not predict answer length, guarantee routing or authenticate a bill.

These explanations describe Examenos's data and display policy. Calculator examples are explicitly hypothetical. Inspect dated endpoint evidence and the formulas; projections do not authenticate a bill.
