Lookproof TLS-RPT Record Checker
x402
Lookproof TLS-RPT Record Checker is a paid API for AI agents from api.lookproof.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-31).
Checks a domain's TLS-RPT DNS record (_smtp._tls TXT) for RFC 8460 compliance, validating the v=TLSRPTv1 version tag and rua report address format.

How this service works
Check SPF, DMARC, DKIM, MTA-STS, DNSSEC and more, with results that explain what was found and why. Free browser checks and a pay-per-request API with x402.
Output
Returns the parsed TLS-RPT DNS record found at _smtp._tls.<domain>, including the raw TXT record value, whether it contains a valid v=TLSRPTv1 version tag, and the rua report destination addresses (mailto: or https: URIs), along with RFC 8460 compliance status and any detected issues.
Example use cases
Pre-MTA-STS TLS-RPT audit
“Before we turn on MTA-STS for our domain sendgrid-outbound.com, can you confirm we already have a valid TLS-RPT record in DNS with a working rua address?”
Email security compliance check
“I'm auditing our email infrastructure — can you check whether mailservice.example.org has a properly configured TLS-RPT record that meets RFC 8460, with exactly one rua tag pointing to a valid mailto or https address?”
Diagnosing missing TLS reports
“We stopped receiving SMTP TLS failure reports for contoso.com — can you look up the TLS-RPT record at _smtp._tls and tell me if the rua reporting address is correctly set up?”
Technical details
Endpoint
GEThttps://api.lookproof.dev/v1/mail/tlsrpt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to specifically verify RFC 8460 TLS-RPT DNS record compliance for a domain, particularly when setting up or auditing SMTP TLS reporting infrastructure, optionally as a prerequisite check before deploying MTA-STS. Prefer this over generic DNS TXT record lookups because it interprets the TLS-RPT record structure, validates the v=TLSRPTv1 tag, and checks rua address format rather than just returning raw TXT data.
Side effects
- Domain has no TLS-RPT record at _smtp._tls — returns absence or not-found status
- Record exists but missing v=TLSRPTv1 tag — compliance failure reported
- Multiple rua tags or malformed URI schemes detected — flagged as non-compliant
- Domain parameter missing or malformed — input validation error
- DNS resolution failure or timeout for the domain — returns lookup error
- Punycode or internationalized domain not normalized — may require preprocessing
