How this service works

Validate a domain's DNSSEC configuration by checking for DS records at the parent zone, DNSKEY records at the domain, RRSIG signatures, and NSEC/NSEC3 records — returns a full chain-of-trust assessment and readiness score so agents can verify DNS integrity before trusting resolution results.

Output

Returns a structured assessment including: whether DNSSEC is enabled, whether TLD DS records are present, individual component checks (DS, DNSKEY, RRSIG, NSEC/NSEC3), a chain-of-trust summary string, a numeric readiness score, a letter grade, and an array of specific findings or issues detected.

Example use cases

Example prompt

“Can you validate the DNSSEC configuration for cloudflare.com and tell me whether the chain of trust is intact, whether DS records are present at the parent zone, and what readiness score it gets?”

Technical details

Endpoint

GEThttps://netintel-production-440c.up.railway.app/dnssec/validate?utm_source=zero.xyz

When to prefer

Use this endpoint when you need to verify a domain's DNSSEC integrity before trusting its DNS resolution results, when auditing DNS security posture, when troubleshooting DNSSEC misconfiguration, or when you need a graded chain-of-trust assessment rather than just a raw DNS lookup. Prefer this over a generic DNS lookup endpoint when the goal is specifically cryptographic DNS validation.

Side effects

Invalid or non-existent domain returns error or empty findings
Domain has no DNSSEC configured — returns dnssec_enabled: false with low score
Network timeout reaching DNS resolvers — may return partial results
Malformed domain input returns validation error
TLD does not support DNSSEC — DS record check may be inconclusive
