Choose this endpoint when an agent needs to verify or discover whether a specific automotive part is compatible with a particular vehicle by year, badge, and model. It is ideal for DIY repair assistants, mechanic tools, or automotive e-commerce agents that need real-time fitment data without maintaining their own parts database. Best used when the user already knows the part type and vehicle details.
