AgentProofs

Trust, observability, and cost attribution for AI agents

Prove what your agents did — and whether it was worth it. Signed proof chains + decision-level cost attribution. EU AI Act ready.

Complete agent accountability

Layer 1: Trust

Proof Chain

Every agent action is cryptographically signed (Ed25519) and hash-chained (SHA-256). Tamper one record and the chain breaks. Verifiable, tamper-evident audit trail.

Layer 2: Observability

AgentTrace

Decision-level cost attribution. See which agent decisions were worth the money, which were waste, and get actionable recommendations with projected savings.
