Why Every Agent Needs A2SPA

🔐

Cryptographic Signatures

Every payload must be SHA-256 hashed and signed with the agent's private key for complete verification.

🔒

Agent Permissions & Toggle

Granular control over agent send/receive permissions with instant ON/OFF toggle capabilities.

🔄

Nonce Replay Protection

Prevents replay attacks with unique nonce verification and 24-hour TTL storage.

📊

ROI Tracking Per Agent

Track time saved and dollar value generated by each agent with detailed analytics.

💰

Pay-as-you-go Billing

Simple $0.01 per verification with transparent usage tracking and real-time balance updates.

📋

Tamper-proof Audit Trail

Complete logging of all agent interactions with CSV export and expandable log details.

The 7 Layers of the AI Agent Stack

A2SPA operates as Layer 5 - the critical Trust Layer that every AI agent framework needs

Every AI agent framework today runs unauthenticated by default. A2SPA is the first to fix that. A2SPA (Agent-to-Secure Payload Authorization) provides the missing cryptographic security layer that ensures every autonomous action is verified, authorized, and auditable.
