Get Your API Key
Create an IPGeolocation account and copy an API key from your dashboard.
- Sign up: https://app.ipgeolocation.io/signup
- Verify your email if prompted
- Sign in: https://app.ipgeolocation.io/login
- Open your dashboard: https://app.ipgeolocation.io/dashboard
- Copy an API key from the
API Keyssection
For server-side code, keep the API key in an environment variable or secret manager. For browser-based single lookups on paid plans, use request-origin auth instead of exposing an API key in frontend code.
Authentication
1. API Key
client, err := ipgeolocation.NewClient(&ipgeolocation.Config{
APIKey: os.Getenv("IPGEO_API_KEY"),
})2. Request-Origin Auth
client, err := ipgeolocation.NewClient(&ipgeolocation.Config{
RequestOrigin: "https://app.example.com",
}) RequestOrigin must be an absolute http or https origin with no path, query string, fragment, or userinfo.
Plan Behavior
Feature availability depends on your plan and request parameters.
| Capability | Free | Paid |
|---|---|---|
| Single IPv4 and IPv6 lookup | Supported | Supported |
| Domain lookup | Not supported | Supported |
| Bulk lookup | Not supported | Supported |
Non-English lang | Not supported | Supported |
| Request-origin auth | Not supported | Supported for /v3/ipgeo only |
Optional modules via include | Not supported | Supported |
include: ["*"] | Base response only | All plan-available modules |
Paid plans still need include for optional modules. fields and excludes only trim the response. They do not turn modules on or unlock paid data.
Client Configuration
| Field | Type | Default | Notes |
|---|---|---|---|
APIKey | string | unset | Required for bulk lookup. Optional for single lookup if RequestOrigin is set. |
RequestOrigin | string | unset | Must be an absolute http or https origin. |
BaseURL | string | https://api.ipgeolocation.io | Override the API base URL. |
ConnectTimeout | time.Duration | 10 * time.Second | Time to open the connection or wait for response headers. |
ReadTimeout | time.Duration | 30 * time.Second | Time to wait while reading the response body. |
Create a client with NewClient . Config values are validated when the client is created. Request values are validated before each request is sent.
Available Methods
| Method | Returns | Notes |
|---|---|---|
LookupIPGeolocation(ctx, request) | *APIResponse[*IPGeolocationResponse] | Single lookup. Typed JSON response. |
LookupIPGeolocationRaw(ctx, request) | *APIResponse[string] | Single lookup. Raw JSON or XML string. |
BulkLookupIPGeolocation(ctx, request) | *APIResponse[[]BulkLookupResult] | Bulk lookup. Typed JSON response. |
BulkLookupIPGeolocationRaw(ctx, request) | *APIResponse[string] | Bulk lookup. Raw JSON or XML string. |
Close() | void | Closes idle HTTP connections and marks the client closed. |

Examples
The examples below assume you already have a configured client in scope:
apiKey := os.Getenv("IPGEO_API_KEY")
client, err := ipgeolocation.NewClient(&ipgeolocation.Config{
APIKey: apiKey,
})
if err != nil {
panic(err)
}
defer client.Close()1. Caller IP
Leave IP empty to look up the public IP of the machine making the request.
response, err := client.LookupIPGeolocation(context.Background(), nil)
if err != nil {
panic(err)
}
if response.Data.IP != nil {
fmt.Println(*response.Data.IP)
}2. Domain Lookup
Domain lookup is a paid-plan feature.
response, err := client.LookupIPGeolocation(context.Background(), &ipgeolocation.LookupRequest{
IP: "ipgeolocation.io",
})
if err != nil {
panic(err)
}
if response.Data.Domain != nil {
fmt.Println(*response.Data.Domain) // ipgeolocation.io
}3. Security and Abuse
response, err := client.LookupIPGeolocation(context.Background(), &ipgeolocation.LookupRequest{
IP: "9.9.9.9",
Include: []string{"security", "abuse"},
})
if err != nil {
panic(err)
}
if response.Data.Security != nil && response.Data.Security.ThreatScore != nil {
fmt.Println(*response.Data.Security.ThreatScore)
}
if response.Data.Abuse != nil && len(response.Data.Abuse.Emails) > 0 {
fmt.Println(response.Data.Abuse.Emails[0])
}4. User-Agent Parsing
To parse a visitor user-agent string, pass Include: []string{"user_agent"} and send the visitor string in the request User-Agent header.
visitorUA := "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_2) AppleWebKit/601.3.9 (KHTML, like Gecko) Version/9.0.2 Safari/601.3.9"
response, err := client.LookupIPGeolocation(context.Background(), &ipgeolocation.LookupRequest{
IP: "115.240.90.163",
Include: []string{"user_agent"},
Headers: map[string]string{
"User-Agent": visitorUA,
},
})
if err != nil {
panic(err)
}
if response.Data.UserAgent != nil && response.Data.UserAgent.Name != nil {
fmt.Println(*response.Data.UserAgent.Name)
}5. Filtered Response
response, err := client.LookupIPGeolocation(context.Background(), &ipgeolocation.LookupRequest{
IP: "8.8.8.8",
Include: []string{"security"},
Fields: []string{"location.country_name", "security.threat_score", "security.is_vpn"},
Excludes: []string{"currency"},
})
if err != nil {
panic(err)
}
if response.Data.Location != nil && response.Data.Location.CountryName != nil {
fmt.Println(*response.Data.Location.CountryName)
}
if response.Data.Security != nil && response.Data.Security.IsVPN != nil {
fmt.Println(*response.Data.Security.IsVPN)
}
fmt.Println(response.Data.Currency == nil)6. Raw XML
response, err := client.LookupIPGeolocationRaw(context.Background(), &ipgeolocation.LookupRequest{
IP: "8.8.8.8",
Output: ipgeolocation.ResponseFormatXML,
})
if err != nil {
panic(err)
}
fmt.Println(response.Data)7. Bulk Lookup
response, err := client.BulkLookupIPGeolocation(context.Background(), &ipgeolocation.BulkLookupRequest{
IPs: []string{"8.8.8.8", "1.1.1.1"},
})
if err != nil {
panic(err)
}
for _, result := range response.Data {
if result.IsSuccess() && result.Data != nil && result.Data.IP != nil {
fmt.Println(*result.Data.IP)
continue
}
if result.Error != nil {
fmt.Println(result.Error.Message)
}
}8. Raw Bulk JSON
response, err := client.BulkLookupIPGeolocationRaw(context.Background(), &ipgeolocation.BulkLookupRequest{
IPs: []string{"8.8.8.8", "1.1.1.1"},
})
if err != nil {
panic(err)
}
fmt.Println(response.Data)Response Metadata
Every method returns APIResponse[T] , where:
-
Datacontains the typed object or raw response string -
Metadatacontains response details such as:-
CreditsCharged -
SuccessfulRecords -
StatusCode -
DurationMS -
RawHeaders
-
Example:
fmt.Println(response.Metadata.StatusCode)
fmt.Println(response.Metadata.DurationMS)
fmt.Println(response.Metadata.FirstHeaderValue("content-type"))Errors
The SDK returns typed errors instead of leaving you to parse error bodies yourself.
| Error Type | When it happens |
|---|---|
*ValidationError | Invalid config, invalid request values, or typed XML request |
*RequestTimeoutError | Connect timeout or read timeout |
*TransportError | Network or transport failure |
*SerializationError | Request or response serialization failure |
*APIError | API returned a non-2xx response |
*APIError has status-specific types:
-
*BadRequestError -
*UnauthorizedError -
*ForbiddenError -
*NotFoundError -
*MethodNotAllowedError -
*ContentTooLargeError -
*UnsupportedMediaTypeError -
*LockedError -
*TooManyRequestsError -
*CustomStatus499Error -
*InternalServerError
Example:
var validationErr *ipgeolocation.ValidationError
_, err := client.LookupIPGeolocation(context.Background(), &ipgeolocation.LookupRequest{
Output: ipgeolocation.ResponseFormatXML,
})
if err != nil {
if errors.As(err, &validationErr) {
fmt.Println(validationErr.Message)
return
}
fmt.Println(err)
}Troubleshooting
- Bulk lookup always requires
APIKey.RequestOriginis not enough. - Typed methods only support JSON. Use the raw methods for XML.
- If you need security, abuse, user-agent, or hostname data, include those modules explicitly.
-
FieldsandExcludesfilter the response. They do not unlock paid data. -
RequestOriginmust be an origin only. Do not include a path, query string, fragment, or userinfo. - Response fields are pointers so omitted fields stay omitted.
Frequently Asked Questions
Can I use this SDK without an API key?
Only for single lookup with paid-plan request-origin auth. Bulk lookup always requires an API key.
Can I request XML and still get typed models?
No. Typed methods only support JSON. Use LookupIPGeolocationRaw or BulkLookupIPGeolocationRaw for XML.
Why are many response fields pointers?
Pointers let the SDK preserve omitted fields instead of inventing zero values for data the API did not send.
Does domain lookup work on the free plan?
No. Domain lookup is a paid-plan feature.
