a2uicatalog.ai

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 Google Trust Services domain-validated
Valid until 14 Dec 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.
DANE / TLSA: Not verified (TLSA query returned RCodeNameError)
Discovery: Well-known document
AI use policy: Search: yesAI input: yesAI training: no

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 — “A2UI Catalog (the A2UI Atomic Catalog)” 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 a2uicatalog.ai controls every word below.
