The cast — four agents, each a real ANS identity

🧍Buyer badge ✓

The traveler's agent. Wants to buy a flight; asks for approval, then books.

🏛️Authority badge ✓

Mints a signed mandate — permission to spend up to a limit with a seller.

🛫Seller badge ✓

The airline agent. Verifies the mandate + proof, then issues the ticket.

🔍Auditor badge ✓

After the booking, independently re-verifies it from public evidence — mandate signature, on-chain settlement, SCITT receipt — and signs a verdict. Copy the evidence bundle and any operator's auditor confirms the same result.

Why it's novel — the tech

🪪 ANS identity

Each agent has a discoverable name (ans://…) and a trust card the others can verify.

🔏 Signed mandates

Spending authority is a signed token — the seller cryptographically checks it before selling.

🎟️ DPoP proof

The buyer proves possession of its key on each call, so a stolen mandate can't be replayed.

🟢 Badge-green trust

On-wire TLS fingerprint matches the ANS badge — no impersonation.

Available agents

Each agent publishes a human guide and a machine-readable /.well-known/interaction-guide.json a buyer agent can follow with no human input.
