AI agents call get_discount_codes to retrieve information from Eduframe without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves discount code information from the Eduframe system. It performs a read-only operation that has no side effects, does not modify or delete data, and does not execute arbitrary code or trigger financial transactions. It simply fetches existing discount code records for viewing or reference purposes.
