Verified by agenttru.st

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 14 Dec 2026. A wildcard certificate: its other hosts are invisible here, because CT logs the wildcard, not them.

Control of the hostname was checked; nothing about who operates it.
DANE / TLSA: Not verified
Discovery: Well-known document
This host also publishes an ARD catalog (/.well-known/ai-catalog.json) declaring 3 resources. The catalog's entries are the publisher's claims, not something agenttru.st verified.
AI use policy: Search: yesAI input: yesAI training: yes

What this site's robots.txt says about how AI may use its content. Recorded as the operator wrote it, not enforced — these are preferences about use, not access, and agenttru.st only reads the agent's own discovery documents.
AI-facing documents: Publishes /llms.txt — “AI CPG Knowledge Graph — GSC · gsc-knowledgegraph.ai · GreenCore Solutions Corp.” a curated map of the site's content for language models

Publishes a Web Bot Auth key directory (1 key, EdDSA) — the operator publishes keys so their agent's signed requests can be verified. agenttru.st recorded that the directory exists; it has not verified a signature.

Fetched from this host during verification. Neither document is how this agent was discovered.

What its catalog declares

From the ARD catalog this host publishes at /.well-known/ai-catalog.json. The operator controls every entry; agenttru.st verified that the catalog exists and parses, and nothing about what the entries say.

Technical agent card

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

Provider: GreenCore Solutions Corp. — what this agent says about itself; other agents claiming the same provider are not thereby related
Protocol: a2a
Version: 1.0.0
Auth schemes: bearerJwt entraOAuth2
Extensions: https://gsc-em.com/a2a/ext/scope-of-authority/v1
GSC scope of authority: read, resolve and discovery calls are autonomous; every transactional commit (order, RFQ acceptance, terms) is human-signed at the GSC Trading Desk / Navigator HITL boundary.
https://gsc-em.com/a2a/ext/knowledge-graph/v1
The AI CPG Knowledge Graph: brands, makers, retail banners, standard pack and compliance, served by the door, every field sourced and dated; counts read from the root record.
https://gsc-em.com/a2a/ext/x402-door/v1
The paid read: /api answers 402 through the gsc-x402.ai rail (x402 v2, Base mainnet, USDC, EIP-3009); receipts signed EdDSA resolve forever on the rail.
https://gsc-em.com/a2a/ext/enforcement-posture/v1
These endpoints are open by design. When the buy side's credential standard reaches GA — expected Q4 2026-Q1 2027 — transactional methods migrate to OAuth 2.1 challenge per the MCP 2025-11-25 specification. Read access stays open. That is not pending w

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: complete all eight fields required by a2a.proto v1.0
