Overview
Gender Detector works by analyzing the name provided and predicting the likely gender of the person. It uses a machine learning model trained on a large dataset of names and their associated genders to make the prediction.

Endpoint
One host, one path per API. The block below shows this call in four languages; every one of them is the same HTTP request. Making requests covers the timeouts, retries and parameter rules that apply to all of them. The SDKs wrap the same call in a typed client.
curl "https://api.apiverve.com/v1/genderdetector?name=John%20Mcdonald&country=US" \
-H "x-api-key: your_api_key_here"const res = await fetch('https://api.apiverve.com/v1/genderdetector?name=John%20Mcdonald&country=US', {
headers: { 'x-api-key': 'your_api_key_here' },
});
if (!res.ok) throw new Error(`${res.status} ${await res.text()}`);
const { data } = await res.json();
console.log(data);import requests
res = requests.get(
"https://api.apiverve.com/v1/genderdetector?name=John%20Mcdonald&country=US",
headers={"x-api-key": "your_api_key_here"},
timeout=15,
)
res.raise_for_status()
print(res.json()["data"])package main
import (
"fmt"
"io"
"net/http"
)
func main() {
req, _ := http.NewRequest("GET", "https://api.apiverve.com/v1/genderdetector?name=John%20Mcdonald&country=US", nil)
req.Header.Set("x-api-key", "your_api_key_here")
res, err := http.DefaultClient.Do(req)
if err != nil {
panic(err)
}
defer res.Body.Close()
out, _ := io.ReadAll(res.Body)
fmt.Println(string(out))
}Replace your_api_key_here with the key from your dashboard. When the inputs arrive as a list rather than one at a time, batch requests run up to 200 of them through this same API in a single call.
Authentication
Send your key in the x-api-key header. That is the only auth step — there is no token exchange and no per-endpoint scope to configure. Authentication covers creating, rotating and revoking keys.
A 401 means the key is missing, invalid or expired. A 403 means the key is valid but not permitted here — blocked by a key restriction or an IP allow-list. Running out of credits is a 429.
Parameters
Sent in the query string. Premium parameters are accepted on every plan but only take effect on plans that include them.
| Parameter | Type | Description |
|---|---|---|
nameRequired | string | The name for which you want to detect the gender |
countryOptional | string | The country code for the name (e.g., US). Recorded and echoed back in the response, but detection does not yet vary by country - the same name returns the same gender whichever code you pass default us · length 2–2 |
Response
Every API returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape. Response format covers the envelope, the other output formats and how premium fields are withheld.
{
"status": "ok",
"error": null,
"data": {
"name": "John Mcdonald",
"country": "US",
"detected": true,
"gender": "male"
}
}
Response fields
Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.
| Field | Type | Example | Description |
|---|---|---|---|
name | string | "John Mcdonald" | The input name submitted for gender detection analysis |
country | string | "US" | The country code as submitted, echoed back. Detection does not yet vary by country |
detected | boolean | true | Always true on a successful response - a name the detector cannot place returns a 404 rather than detected: false |
gender | string | "male" | The predicted gender of the person based on name analysis |
Errors
Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change. Error handling covers the full status list and which of them are worth retrying.
| Status | Meaning | What to do |
|---|---|---|
400 | Input was rejected | Read error; it names the parameter. |
401 | Key missing or invalid | Check the header name and the key value. |
403 | Key valid, but not permitted | A key restriction or IP allow-list; see key scoping. |
429 | Rate limited, or out of credits | Read error to tell them apart; see rate limits. |
Use cases
- Email Salutation Selection
- When drafting automated outreach, sales platforms choose correct honorifics and greeting styles based on the predicted gender returned for each recipient.
- Account Profile Onboarding
- Assign default avatars and profile pronouns automatically when a user signs up by matching their entered first name against regional gender predictions.
- Audience Demographic Audits
- To evaluate subscriber breakdowns without intrusive survey forms, newsletter editors tabulate aggregate gender distributions across their imported subscriber lists.
- Personalized Catalog Navigation
- Ecommerce fashion apps preselect relevant apparel landing tabs for new accounts by checking customer first names against country-specific gender results.
