# Use Cases
source: https://developer.mastercard.com/mastercard-agent-pay/documentation/use-cases/index.md

👉 Use this page to outline the entire end to end user journey. It is important that you document the distinct sequence of calls that your service uses. A customer must be able to understand the flow of data from one call to the next. In other words, what information from a response is then used in a sequential request, and so on. Create a paragraph (or bullet points) here that outlines this and a table that shows all the use cases. You must use a singular mermaidJS diagram to add a visual diagram of this below as well, do not use your own imagery. For documentation about how to use mermaidJS within JAMStack see [the diagram shortcode documentation](https://stage.developer.mastercard.com/jamstack/documentation/theme/shortcodes/diagram/).

The {Pet Store API} offers endpoints categorized into Dogs, Cats, Pets, Adoptions, and Employees. This robust system enables advanced pet management operations including status-based pet searches, adoption record retrieval, secure employee authentication via Social Security Number (SSN) lookup, and full CRUD operations for both pet and employee records.

Built with enterprise-grade architecture, these core functionalities deliver precise data tracking and streamlined information management, establishing a reliable foundation for scalable database operations and business process automation.
