“Luca keeps the accounting record of payments made by AI agents. Agents declare an intent before paying and report what they paid; the other side of a payment reads, confirms or proposes changes to its label. Luca never moves or holds money.

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of sandbox.luca.network controls every word below.

Declare an intent before paying

Declare what you are about to buy and why, before paying. Returns an intent ID, the mandate check and the expiry. Amounts are integers in the currency's minor unit. For an agent key.

Check a payment before paying

Ask whether this payment is allowed: registration approved, an open intent that fits, within the mandate. Answers approve or decline with reasons. For an agent key.

  • {"skill":"check_payment","input":{"rail":"x402","amount_minor":1200,"currency":"USDC","intent_id":"int_…"}}

Get the label of a payment
