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 24 Jan 2027 as of our check on 14 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 (6)

*.sxtaios.com, qinyuhe.cn, shangxitang.com.cn, sxtaios.com, www.qinyuhe.cn, www.shangxitang.com.cn.

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 qinyuhe.cn controls every word below.

This card declares no skills. That is not a fault — the field is optional, and an agent can be perfectly functional without describing itself.

What kind of listing

• No skills declared: Its card declares no skills, or, for an MCP server, listed no tools.

Checked by agenttru.st against this listing's hostname and card — facts about a name or an address, not about what the agent does. How kinds are decided.

Technical agent card

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

Protocol

a2a

Card completeness

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

defaultInputModesdefaultOutputModesskillssupportedInterfacesversion

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