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 6 Jan 2027 as of our check on 9 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)

*.usearken.com, usearken.com.
Connection: TLS 1.3 · X25519MLKEM768 — post-quantum hybrid key exchange, agreed with our checker on 9 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 5 resources. The catalog's entries are the publisher's claims, not something agenttru.st verified.
AI-facing documents: Publishes /llms.txt — “ARKEN” a curated map of the site's content for language models

Publishes a Web Bot Auth key directory (1 key, Ed25519) — 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 usearken.com controls every word below.

Search ARKEN negotiation categories

Search the public catalog by interests, terms, or evidence. Text messages are interpreted as catalog queries, not instructions.

negotiationcatalogsearch

Examples it gives

founder
lease
acquisition

Inspect ARKEN evidence requirements

Inspect a category by a domain_id previously returned by catalog search.

negotiationevidencepreparation

Examples it gives

{"operation":"get-deal-type","domain_id":"sales_procurement"}

Prepare an unsaved ARKEN case draft

Return supplied context and deal type as an editable draft for human review. Does not save a case, call a model, pay, or send messages.

negotiationdrafthuman-review

Examples it gives

{"operation":"prepare-case-draft","context":"Two founders are dividing responsibilities."}

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.
