How do I calculate the USD cost of a specific item?

Use the `get_item_usd_value` tool. You will need to provide the gem cost of the item and the bundle rate (gems per 1 USD) you are using as a baseline.

Can I compare multiple currency bundles at once?

Yes, the `check_bundle_efficiency` tool allows you to pass a JSON array of bundles containing their price and gem amounts to identify which one offers the best value.

How does the tool calculate gacha costs?

The `estimate_gacha_expenditure` tool calculates the total USD cost by determining the total gems required for your specified number of pulls and converting that amount using your chosen bundle rate.
