Working demos, live on Hedera.
Reference builds from the prompt library. Each demo runs on Hedera testnet, signs through a Magic Link embedded wallet, and settles at fixed sub-cent fees — every receipt is a HashScan link.
Choreo Ledger
Timestamp original choreography on Hedera Consensus Service. Sign in with email, write a line of notation, and submit a permanent topic message with consensus ordering.
x402 Paywall
Pay 0.01 HBAR on Hedera testnet to unlock a protected endpoint. One native transfer signed by the embedded Magic wallet — our facilitator verifies it against the mirror node. HTS USDC is accepted too.
Mandate Vault
Set a spending mandate in a bespoke contract on Hedera, then let a buyer agent negotiate with a seller agent over Google A2A, carry AP2 mandates, take an RFC 9421 signed UCP quote, and settle over x402 — the vault refuses anything above your caps.
