A verifiable identity for every AI agent
Register an agent and it gets an ML-DSA-44 passport — a post-quantum cryptographic identity. From then on, every action it takes is signed. Anyone can verify a MOSS passport and the receipts behind it: offline, years later, without access to MOSS.
Register an agent
One API call, or sign up with your email. MOSS issues an ML-DSA-44 passport — a post-quantum keypair bound to that agent's identity.
Sign every action
Your agent calls MOSS before it acts. Each action is checked against your policy and sealed into a signed receipt the moment it happens.
Anyone can verify
Every receipt has a public URL. Regulators, customers, and auditors verify the ML-DSA-44 signature themselves — no access to MOSS required.
