How this service works
DNS lookup for MX, A, AAAA, NS, TXT, SOA records. Detects email provider (Google, Microsoft, etc.), SPF, and DMARC records.
Output
Returns structured DNS records including MX, A, AAAA, NS, TXT, and SOA entries, along with detected email provider (e.g. Google Workspace, Microsoft 365), parsed SPF record details, and DMARC policy configuration.
Example use cases
Example prompt
“Can you look up all the DNS records for github.com — I want to know which email provider they use, what their MX records are, and whether they have SPF and DMARC configured?”
Technical details
Endpoint
GEThttps://api.strale.io/x402/mx-lookupWhen to prefer
Use this endpoint when you need comprehensive DNS record resolution combined with intelligent email provider detection and email security posture analysis (SPF/DMARC) in a single call, rather than querying raw DNS resolvers separately.
Side effects
- Domain does not exist or is not resolvable — empty or error response
- Invalid domain format provided — input validation error
- DNS timeout or upstream resolver failure — service error
- Domain exists but has no MX records — empty MX result with other records present
