FAQ
Which token fields does the analyzer use?
It uses numeric usage fields such as input_tokens, cache_creation_input_tokens, cache_read_input_tokens, and output_tokens when present on transcript records.
Can this estimate differ from my Claude bill?
Yes. Pricing date, product plan, provider, region, caching behavior, batch discounts, and official billing reconciliation can all differ from a local estimate.
