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 2 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 — “x402 — GSC · gsc-x402.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 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 gsc-x402.ai controls every word below.

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.

gsc-x402.ai/api — the x402 door (Base mainnet, USDC)

json

GSC's machine-payments door: unpaid GET answers 402 with the terms in the payload; a v2 client pays on Base; the door answers 200 with a receipt signed EdDSA that resolves forever at /x402/receipt/{nonce}. Operated by GreenCore Solutions Corp.

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/x402-door/v1
GSC's machine-payments door: one paid GET (/api, x402 v2, Base mainnet, USDC, EIP-3009), a receipt signed EdDSA that resolves forever, the signing key at /x402/jwks.json.
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
