How this service works
DNSSEC status for a domain using Cloudflare's public resolver (1.1.1.1 DNS-over-HTTPS): whether the resolver validated the answer (AD flag), the DS records in the parent zone, and the DNSKEY records with key-signing keys. The validation is done by Cloudflare's resolver, not by this tool walking the chain to the root.
Output
Returns a JSON object with: the domain checked, a verdict string (e.g. VALIDATED_BY_RESOLVER, UNSIGNED), whether the resolver set the AD flag (resolverValidated boolean), the RCODE for the A record query, an array of DS records (keyTag, algorithm, digestType), the count of DNSKEY records, the number of key-signing keys, the source resolver URL, and a timestamp. Also includes a note clarifying that validation relies on Cloudflare's resolver AD flag rather than an independent chain walk.
Example use cases
Pre-deployment DNSSEC audit
“Before we go live, can you check if example.com has DNSSEC properly set up — does it have DS records in the parent zone and does Cloudflare's resolver validate it with the AD flag?”
Security compliance domain check
“I need to verify that cloudflare.com passes DNSSEC validation — can you tell me if the resolver marks it as validated, how many DNSKEY records it has, and whether there are key-signing keys?”
Investigating DNS trust issues
“We're seeing DNS trust warnings for paypal.com — can you check its DNSSEC status, whether Cloudflare's resolver validates it, and if DS records exist in the parent zone?”
Technical details
Endpoint
GEThttps://api.fadeandco.workers.dev/api/agent-intel/dnssec-trust-chain-validator?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, resolver-perspective DNSSEC status check using Cloudflare's 1.1.1.1 infrastructure. It's ideal for automated compliance checks, pre-deployment audits, or security monitoring where you want to know if a domain is DNSSEC-signed and resolver-validated without running your own full chain validation. Not suitable if you need an independent cryptographic chain-walk from the root, or if you need to validate DNSSEC signatures yourself rather than relying on a trusted resolver's AD flag.
Side effects
- Domain does not exist (NXDOMAIN) — may return RCODE 3 with no DS/DNSKEY data
- Domain has no DS record in parent zone — verdict is UNSIGNED
- Resolver unreachable — timeout or upstream error from Cloudflare 1.1.1.1
- Invalid or malformed domain input — may return an error or unexpected result
- Domain exists but DNSSEC is misconfigured — resolver may return SERVFAIL (RCODE 2)
