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 6 Feb 2027 as of our check on 8 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)

*.hsk-challenge.pages.dev, hsk-challenge.pages.dev.

Connection

TLS 1.3 · X25519MLKEM768 — post-quantum hybrid key exchange, agreed with our checker on 8 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 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 — “Chinese Tips · 中文通” a curated map of the site's content for language models

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

What this agent says it can do

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.
