More than processing a request
KeyRunner does not just forward traffic. It adds control, safety, and visibility around every API interaction.
Every request can be checked, filtered, and handled with stronger guardrails.
KeyRunner adds governance, observability, and runtime boundaries around each interaction.
It is not just request forwarding. It is request control with policy and context.
Give agents capability. Not credentials.
Start with the free API client for developers. Add policy enforcement, credential isolation, and audit trails when your agentic workflows need enterprise-grade governance.
Credentials are injected at runtime, inside your infrastructure. Agents invoke named actions, nothing more.
