API-Equivalent Cost
What your AI usage would have cost at pay-per-token prices, useful even when you pay a flat subscription.
Definition
What a session's tokens would cost at API list prices. It is a yardstick for usage on subscription plans such as Claude Pro or Max, which are not billed per token, so it is not what the subscriber actually pays.
Example
A day of Claude Code on a Max plan logs millions of cached-read tokens; the usage tool prices them at API rates for comparison.
