API Value = what this usage would cost at API prices; subscriptions are not billed per token.

illustrative numbers; the table format is the real one

03 privacy

no network. The binary opens no sockets. Prices come from a built-in table, an embedded LiteLLM snapshot and your config.
no writes. It never creates, changes, locks or deletes a file. A test runs it against read-only logs.
no credentials. It never reads token or auth files; from the account file it reads only the fields used for labels.

Try it in five seconds.

npx acusage

reads your local logs, prints a table, touches nothing
