x402

Domain Trust Report is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Runs a composite security and trust assessment on a domain, combining TLS, HTTP headers, security.txt, RDAP, DNS, and uptime signals into a single report.

How this service works

One-call domain trust and security report with TLS, headers, security.txt, RDAP, DNS, and uptime signals.

Output

A composite trust report covering: TLS certificate validity and configuration, HTTP security header presence (e.g. HSTS, CSP, X-Frame-Options), security.txt existence and contents, RDAP registrar and registration date data, DNS record signals, and uptime/availability indicators — all aggregated into a single structured response.

Example use cases

Example prompt

“Can you run a full trust report on stripe.com — I want to see its TLS status, security headers, security.txt, DNS records, RDAP registration info, and uptime signals before we integrate with it?”

Technical details

Endpoint

POSThttps://api.delx.ai/api/v1/x402/domain-trust-report

When to prefer

Use this endpoint when you need a comprehensive, multi-signal security and trust picture of a domain in a single call — especially before integrating with a third-party service, vetting an outreach target, or making trust-based routing decisions. It aggregates TLS, headers, security.txt, RDAP, DNS, and uptime checks that would otherwise require 5–6 separate API calls.

Side effects

Domain does not exist or is unresolvable — DNS lookup fails
TLS certificate is expired or misconfigured — partial report returned
RDAP registry returns no data for the domain — field absent in response
Target domain blocks automated requests — uptime check may time out
Invalid domain format submitted — validation error returned
Upstream DNS or RDAP services temporarily unavailable — partial results with error flags
