### Access Long-Term Commercial Data

## Use Cases

### Comparing USD vs. Commercial Rates
A financial analyst needs to compare the current official PTAX rate with the long-term commercial SGS data for risk assessment. The agent runs `get_cotacao_dolar` and then `get_dolar_sgs`, providing a dual analysis in seconds.

### Pricing an International Contract
A sales manager needs to quote a client based on the latest Euro rate. They ask their agent, which uses `get_cotacao_moeda` (for EUR), and immediately returns the current BRL equivalent for accurate billing.

### Building Time-Series Reports
A reporter needs to show currency movements over the last quarter. The agent calls `get_dolar_periodo`, pulling a full historical table of daily rates, which is then formatted into a professional report.

### Validating Currency Codes
Before processing a payment batch, an operations team member uses the agent to call `listar_moedas`, verifying that every required currency code (e.g., MXN, COP) is current and supported.

## Benefits

- Complete Reference: Use `listar_moedas` to get a full, validated list of all available currency codes, ensuring your agent never uses an invalid code.
- Dual Viewpoints: Comparing PTAX rates with the SGS commercial series via `get_dolar_sgs` allows you to analyze both official and market-based dollar trends.
