Zelta
Zelta provides an AI Safety Gateway called ApprovalLayer that helps autonomous AI agents safely execute high-impact actions using policies, hybrid AI risk classification, human approvals, audit trails, and execution tokens. It ensures that agent actions are proposed, evaluated by policy engines, risk classifiers, reviewed by humans if needed, and then executed with a one-time token to prevent replay. The platform integrates with AI agents via HTTP API, offering features like deterministic policy rules, hybrid AI risk classification (shadow, hybrid, enforce modes), human review queues with SLAs, immutable audit logs, and notifications. It is designed for enterprise controls, giving teams visibility and control over agent actions before execution, ensuring compliance and security. The architecture centralizes proposal, policy, risk, review, token issuance, audit, and notifications without replacing the agent runtime. Developers can integrate in minutes using simple API calls.

Problem solved
Autonomous AI agents can execute high-impact actions like mutating production data, accessing secrets, or changing permissions without a deterministic gate between intent and execution. Zelta solves this by providing a pre-execution gateway that evaluates actions against policies, risk signals, and human approvals, ensuring only authorized and reviewed actions are executed with audit trails and single-use tokens to prevent replay.
Use cases
- Safely execute financial refunds by AI agents
