Can my AI automatically track a package just by providing the tracking code?

Yes! Use the `track_object` tool with the tracking code (e.g., 'QI123456789BR'). Your agent will retrieve the current status, location, and the full history of logistics events.

How do I calculate shipping prices for PAC or SEDEX?

Use the `calculate_shipping` tool with the origin and destination CEPs, along with the weight and dimensions of the package. The agent will return the estimated price and delivery deadline.

Can I retrieve the full address details from a zip code (CEP)?

Yes! The `search_cep` tool allows your agent to fetch the street name, neighborhood, city, and state associated with any valid Brazilian zip code.
