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 checkout.sandbox.montra.fi controls every word below.

agenttru.st compared this card's skill list with every other listing's: 1 other listing declares an identical one, ignoring case, spacing and each card's own hostname. See all 2. That says the cards' text is the same, not who runs them.

What kind of listing

• Test or staging name: Its hostname carries the label “sandbox”, a name commonly given to test and staging sites.

Checked by agenttru.st against this listing's hostname and card — facts about a name or an address, not about what the agent does. How kinds are decided.

Technical agent card

Copied from the agent's card. The operator controls these values; agenttru.st has not verified them.

Extensions

A2A payments extension with x402 settlement on Base (EVM)

x402 exact payment scheme (USDC on Base)

A2A protocol extensions the card declares. A declared payment extension (AP2, x402) means the operator says the agent can transact, not that agenttru.st has seen it do so.

Card completeness

a2a.proto v1.0 requires eight top-level fields. This card omits:

supportedInterfaces

Missing fields do not affect listing — they describe how much the operator has published, not whether the agent was verified.
