Create a new client

To start making requests you need the API Key. You can find it on your profile page on whoisxmlapi.com. Using the API Key you can create Client.

Most users will be fine with NewBasicClient function.

client := registrantalert.NewBasicClient(apiKey)

If you want to set custom http.Client to use proxy then you can use NewClient function.

transport := &http.Transport{Proxy: http.ProxyURL(proxyUrl)}

client := registrantalert.NewClient(apiKey, registrantalert.ClientParams{
    HTTPClient: &http.Client{
        Transport: transport,
        Timeout:   20 * time.Second,
    },
})

Make basic requests

Registrant Alert API lets you monitor specific domain registrants to be alerted whenever their information is linked to a newly-registered or just-expired domain name.

Basic search requires less configuration and produces broader results.

// Make request to get a list of all domains matching the criteria.
registrantAlertResp, _, err := client.BasicPurchase(ctx,
    &registrantalert.BasicSearchTerms{[]string{"Airbnb", "US"}, []string{"Europe", "EU"}})

for _, obj := range registrantAlertResp.DomainsList {
    log.Println(obj.DomainName)
}


// Make request to get only domains count.
domainsCount, _, err := client.BasicPreview(ctx,
    &registrantalert.BasicSearchTerms{[]string{"Google"}})

log.Println(domainsCount)

// Make request to get raw data in XML.
resp, err := client.BasicRawData(ctx,
    &registrantalert.SearchTerms{"google", "blog"},
    &registrantalert.SearchTerms{"analytics"},
    registrantalert.OptionResponseFormat("XML"))

log.Println(string(resp.Body))

Advanced usage

Advanced search allows searching through specific WHOIS fields.

registrantAlertResp, resp, err := client.AdvancedPurchase(ctx,
    []registrantalert.AdvancedSearchTerm{{"RegistrantContact.Organization", "Airbnb, Inc.", true}},
    registrantalert.OptionSinceDate(time.Date(2022, 11, 01, 0, 0, 0, 0, time.UTC)))
