How this service works
Domain lookup: availability, registrar, created and expiry dates (RDAP/WHOIS), nameservers, A/AAAA/MX/NS/TXT records, and whether the site answers over HTTPS.
Output
Returns domain availability status, RDAP/WHOIS data (registrar, creation date, expiry date), nameservers, DNS records (A, AAAA, MX, NS, TXT), and whether the domain responds over HTTPS.
Example use cases
Domain availability check before purchase
“Is acmestartup.io available to register? If not, who owns it and when does it expire?”
Verify domain DNS configuration
“Look up the MX records and nameservers for mycompany.com so I can confirm email routing is set up correctly.”
Competitive domain intelligence
“Pull all the DNS and WHOIS info for competitor.com — I want to know the registrar, creation date, expiry, and whether they're running HTTPS.”
Technical details
Endpoint
GEThttps://agentrxi.com/v1/domain?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a comprehensive, one-call snapshot of a domain's registration, DNS, and HTTPS status. It combines RDAP/WHOIS, DNS resolution, and HTTPS probing in a single pay-per-call request, making it ideal for agents that need domain intelligence without stitching together multiple separate DNS and WHOIS APIs.
Side effects
- Invalid domain format returns an error
- Domain not found in RDAP/WHOIS may return partial results
- Newly registered domains may have incomplete RDAP data
- DNS propagation delays may cause stale or missing records
- Timeout if the upstream RDAP or DNS resolver is slow
