Everything here is a check agenttru.st performed itself. Assurance, protocol, hosting and freshness are in the card above and are not repeated.

Certificate

Issued by Google Trust Services domain-validated

Valid until 18 Jan 2027 as of our check on 11 Nov 2026.

Control of the hostname was checked; nothing about who operates it.

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 www.openstoa.xyz 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.

Technical agent card

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

Provider

ZKProofport — what this agent says about itself; other agents claiming the same provider are not thereby related

Protocol

a2a

Version

1.0.0

Card completeness

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

defaultInputModesdefaultOutputModessupportedInterfaces

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