How this service works
Signal Nodus: year-over-year diffs of SEC filing sections, pinned to accession numbers. The diff is the product; raw data is the on-ramp.
Output
A JSON object containing: whether the domain has SPF (boolean), domain age in days (integer), whether the domain currently resolves (boolean), the registrar name, and an array of nameservers. Example: {hasSpf: false, ageDays: 11208, resolves: true, registrar: 'ICANN', nameservers: ['a.iana-servers.net']}.
Example use cases
Email sender reputation check
“Before we allow emails from this vendor, check the domain vendorxyz.com — does it have SPF configured, how old is it, and does it resolve? I want to make sure it's not a throwaway domain.”
Phishing domain triage
“We got a suspicious link pointing to secure-paypa1.net — can you pull a domain report on it and tell me the age, registrar, nameservers, and whether SPF is set? Trying to assess if it's a phishing domain.”
Competitor infrastructure research
“I'm researching our competitor acmecorp.io — what registrar are they using, how long has the domain been around, and what nameservers are they on?”
Technical details
Endpoint
GEThttps://api.signalnodus.ai/v1/domain/report?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, fast domain intelligence snapshot — especially SPF presence, domain age, registrar, and resolution status — as a first-pass trust signal for a domain. It is well-suited for phishing triage, vendor vetting, or email security checks where a single structured JSON response is preferred over scraping WHOIS or querying multiple DNS tools manually.
Side effects
- Domain not found or invalid input returns empty or error response
- Unregistered or expired domains may return resolves: false with minimal other data
- SPF detection may lag if DNS records were recently updated
- Rate limiting or payment failure (x402) may prevent successful response
- Nameserver data may be incomplete for privacy-shielded registrations
