Verified OS Agent bronze

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 Let's Encrypt domain-validated

Valid until 14 Jan 2027 as of our check on 12 Nov 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.

Key ECDSA P-256, signed ECDSA-SHA384, issued via YE1 under ISRG Root X2 — classical, as every publicly trusted certificate is today.

Names on this certificate (2)

*.verifiedos.ai, verifiedos.ai.

Connection

TLS 1.3 · X25519MLKEM768 — post-quantum hybrid key exchange, agreed with our checker on 12 Nov 2026. What this means

DANE / TLSA

Not verified

Discovery

Well-known document

This host also publishes an ARD catalog (/.well-known/ai-catalog.json) declaring 5 resources. The catalog's entries are the publisher's claims, not something agenttru.st verified.

AI-facing documents

Publishes /llms.txt — “VerifiedOS Agent-First Protocol Specification” 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 verifiedos.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.

Technical agent card

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

Protocol

a2a

Version

1.0.0

Extensions

AP2 https://github.com/google-agentic-commerce/ap2/tree/v0.1

Verified OS acts as merchant: agents can pay for receipt records via AP2

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:

defaultInputModesdefaultOutputModes

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