How this service works
Domain Intel ($0.012): domain identity & trust posture in one call — RDAP registration data (registrar, creation/expiration/last-changed dates, status, nameservers, or a clean not-registered result), live DNS email-authentication read (MX/SPF/DMARC/NS), and a heuristic posture summary (e.g. newly-registered + no SPF/DMARC = elevated impersonation risk). Fetched live from IANA's RDAP bootstrap + the TLD registry's own RDAP server, and this server's own DNS resolver (no third-party DoH relay).…
Output
A structured response containing: RDAP data (registrar name, creation/expiration/last-changed dates, domain status flags, nameservers) or a clean not-registered result; live DNS records (MX, SPF, DMARC, NS); and a heuristic posture summary that combines signals — e.g. flagging newly-registered + missing SPF/DMARC as elevated impersonation risk.
Example use cases
Phishing domain triage
“I just got an email from payments-secure-verify.com — can you check its registration age, whether it has SPF and DMARC configured, and flag whether it looks like a phishing or impersonation risk?”
Vendor due diligence before onboarding
“Before we set up an API integration with acmecorp-vendors.io, can you pull its domain registration info, check its DNS email authentication records, and give me a trust posture summary?”
Brand protection monitoring check
“Can you run a domain intel check on brandname-support.net to see when it was registered, who the registrar is, and whether the lack of DMARC makes it a likely brand impersonation threat?”
Technical details
Endpoint
POSThttps://draconic21-x402-api.onrender.com/v1/domain_intel?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, single-call snapshot of a domain's identity and trust posture — combining RDAP registration data with live DNS email-authentication records and a heuristic risk summary. It is preferable to standalone WHOIS or DNS tools because it resolves directly against IANA's RDAP bootstrap and the TLD's own registry (no third-party relay), and it synthesizes SPF/DMARC absence into an actionable risk signal rather than returning raw records only. Ideal for phishing triage, vendor due diligence, brand protection checks, and any agentic workflow that needs domain trust context without orchestrating multiple separate lookups.
Side effects
- Domain not found in any RDAP registry — returns a clean not-registered result rather than an error
- TLD registry RDAP server unresponsive or rate-limiting — may return partial or timeout error
- Invalid domain input (malformed string) — returns validation error
- DNS resolution failure for the target domain — DNS records section may be empty or partial
- Network latency from Render-hosted cold start may add delay on first request
