AI agents call list_offers to retrieve information from Keycrm 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 existing offer/product variant data from the keyCRM system. It performs a read-only operation with no ability to create, modify, delete, or execute external actions. The presence of optional filters suggests it is a standard query/list operation.
