DNS for AI Discovery (DNS-AID) Checker

Query DNS for agent discovery records published under DNS-AID or the AID convention.

Looks up the SVCB index at _index._agents.<domain> and the inventory leaf described by the DNS-AID Internet-Draft, plus the separate AID convention's TXT record at _agent.<domain>. These are two different unratified proposals for publishing agents in DNS; the result names whichever one it finds.

This is one of the checks the AI Agent Readiness Checker scores under Discoverability, and it can also be run on its own for any URL.

About this validation

Experimental / emerging convention

Looks for agent discovery records published in DNS rather than over HTTP. Two separate unratified conventions exist: DNS-AID, an IETF Internet-Draft using an SVCB index at _index._agents.<domain>, and AID, a community convention using a single TXT record at _agent.<domain>. The result names whichever one was actually found; they are not the same specification.
