A2A Passport — the maker and the banner, verified — gtinfetch by GSC
⚠ This card does not identify A2A Passport.
It identifies itself as GreenCore Solutions Corp.
at
gsc-em.com
On the gtinfetch record, A2A Passport verifies the maker and the retail banner behind every product an agent orders.
⚠ Agent card, not A2A. GreenCore Solutions Corp. serves a machine-readable agent
manifest at the A2A discovery path, but it fails a structural check in the A2A 1.0.0
, which is not
A2A Passport’s registered domain
(AgentCard object. It is an agent card in spirit rather than in schema — useful for
discovery, but an A2A client cannot assume it will parse.
capabilities-not-object
a2a-passport.ai).
It was found at this path because A2A Passport’s record references that host. That happens for a product or a parent company as readily as for an unrelated one, so we do not claim A2A Passport serves this agent endpoint — the card is reproduced here as published, and the identity above is the card’s own.
Discovery
An A2A client finds this agent by fetching the well-known path on the host below. An agent card cannot be derived, generated or reconstructed on anyone’s behalf — whoever serves it published it — but this host is not A2A Passport’s own, so the card is evidence about GreenCore Solutions Corp. rather than about A2A Passport.
