Agent Card Schema Reference

Overview

The Agent Card is a JSON document that serves as the passport for autonomous agents in the AgentVault ecosystem. It provides essential metadata about an agent, including its capabilities, authentication requirements, available skills, and endpoint information. Think of it as a machine-readable business card that enables automatic discovery, authentication, and interaction between agents.

The Agent Card follows the A2A (Agent-to-Agent) protocol specifications and enables:

• Automatic Discovery: Agents can be discovered and understood by other agents
• Authentication Negotiation: Clients can determine which authentication scheme to use
• Capability Verification: Clients can understand what an agent can do before connecting

Identity Fabric Architecture

Overview

The Identity Fabric is the Zero-Trust security foundation of the Sovereign Stack, providing cryptographic workload identities through SPIFFE/SPIRE and fine-grained authorization through Open Policy Agent (OPA). It ensures that every service and agent in the ecosystem has a unique, verifiable identity that cannot be forged, creating a trustless environment where security is cryptographic rather than perimeter-based.

# Quantum Agent Card Schema Reference
## The Protocol Quantum-Enhanced Schema v2.0

## Overview

The Quantum Agent Card extends the current The Protocol Agent Card schema to support quantum computing capabilities, enabling agents to participate in the emerging quantum computation marketplace. This schema introduces quantum-specific roles, hardware specifications, and economic models for the quantum era.

The Quantum Agent Card enables:
- **Quantum Service Discovery**: Find quantum encoders, decoders, and QPU providers
- **Hardware Specifications**: Declare quantum hardware capabilities
