Connection

TLS 1.3 · X25519 — classical key exchange, agreed with our checker on 11 Nov 2026. What this means

DANE / TLSA

Not verified (TLSA query returned RCodeNameError)

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 — “TariffWatch HQ” 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

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of tariffwatchhq.com 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.
