## Use Cases

### Pricing international products after a major rate shift
An e-commerce manager needs to know how much 10,000 units of goods cost in the local currency two years ago. They ask their agent to use `get_historical_rates` and get an immediate, audited price point for comparison.

### Financial modeling of global market risk
A data analyst needs a five-year view of the USD/EUR rate volatility. They ask their agent to use `get_timeseries` across 365 days each year, generating clean, structured data for immediate visualization.

### Checking budget conversions for travel
A user needs to know if a $200 trip budget from the US will cover expenses in Japan next month. They ask their agent to use `get_latest_rates` and get real-time conversion figures.

### Validating old financial reports
An auditor needs to verify a transaction recorded on 2010-12-25. They ask their agent to use `get_historical_rates` and confirm the precise exchange rate used at that time.
