# Implement DNS for AI Discovery (DNS-AID) Publish DNS for AI Discovery (DNS-AID) records so agents can discover your agent endpoints through DNS. ## Requirements - Publish DNS for AI Discovery (DNS-AID) records under your domain's `_agents` namespace, such as `_index._agents.example.com` or `_a2a._agents.example.com` - Use ServiceMode `SVCB` records, or `HTTPS` records for HTTPS endpoints, with `alpn` and endpoint connection parameters - Use numeric `keyNNNNN` SvcParamKey names for experimental DNS for AI Discovery (DNS-AID) custom parameters until they are registered - Sign public DNS for AI Discovery (DNS-AID) discovery zones with DNSSEC so validating resolvers return authenticated data ## Example ```dns _a2a._agents.example.com. 3600 IN SVCB 1 agent.example.com. alpn="a2a" port=443 mandatory=alpn,port ``` ## Validate The scanner validates DNS for AI Discovery (DNS-AID) via DNS-over-HTTPS. By default, the scanner uses Cloudflare's `https://cloudflare-dns.com/dns-query` with automatic fallback to `https://dns.google/resolve` on resolver-level failures. Library callers can override the resolver with `ScanOptions.dohResolverUrl` (disables fallback). ```http POST https://isitagentready.com/api/scan Content-Type: application/json {"url": "https://YOUR-SITE.com"} ``` Check that `checks.discoverability.dnsAid.status` is `"pass"`. ## References - [draft-mozleywilliams-dnsop-dnsaid](https://datatracker.ietf.org/doc/draft-mozleywilliams-dnsop-dnsaid/) - [RFC 9460 — SVCB ...
