The video tutorial guides viewers through building an exchange rate model using the Exchange Rate API. It covers accessing the API without a key, using the API endpoint, and structuring the model with necessary keys and data types. The tutorial also explains creating structs for query and info, finalizing the model, and preparing for further development.
