Description APIShield Gateway is a security and control module for teams that expose or consume APIs inside AI systems. AI products often depend on many internal and external APIs: model APIs, tool APIs, data APIs, workflow APIs, and third party services. Without a control layer, those APIs can become a source of data leakage, abuse, unstable costs, unauthorized access, and unsafe automation. This module provides patterns for request validation, authentication handling, rate control, allow and deny rules, logging, error normalization, and controlled routing. It can be used as an internal gateway between AI agents and tools, between platforms and model services, or between external clients and internal inference endpoints. A typical workflow is to define protected routes, configure access rules, validate requests, enforce quotas, log calls, and forward approved requests to downstream services. The module is not a full enterprise API management platform, but it provides a practical security mediation layer. For production use, teams should integrate it with identity systems, secrets management, observability, incident response, and formal security review.
