Domain WHOIS & DNS Lookup

omnial/domain-info

Given a domain name, returns its WHOIS record (registrar, creation/expiration/last-updated dates, nameservers, registration status, country) and its DNS records (A, AAAA, MX, NS, TXT, CNAME). A domain with no WHOIS record on file (e.g. unregistered) returns a `whois_error` flag instead of a `whois` object, with empty DNS record arrays.

// 1. search: find the tool
omnial_search({ query: "what you need" })

// 2. inspect: price and input schema
omnial_inspect({ tool: "omnial/domain-info" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "omnial/domain-info" })

// 4. run: price the exact call first, then run it
omnial_execute({ tool: "omnial/domain-info", input: { /* see input_schema */ }, dry_run: true })
omnial_execute({ tool: "omnial/domain-info", input: { /* ... */ } })

// 5. settle: the call is charged when it finishes, nothing to do
