## 制作人员、未知结果和用途

成功完成且返回 gender: null 的预测，按所选模式扣除积分。电话号码验证即使返回 valid: false，也消耗 1 积分。计费前的输入验证错误不扣除积分；预测失败且退款已确认时，净消耗为 0。

正的起始余额足以开始单个请求或批次。最后扣除可能会使余额为负数。例如，从 1 个积分开始，使用需要 2 个积分的 AI 操作，则余额为 -1。零余额或负余额会阻止需要积分的新操作。退款仍然是可能的。

检查meta.usage.billing_status。值not_charged表示没有扣除积分，charged_credits: 0。值 confirmed 表示最终成本已知。 unconfirmed表示charged_credits为null，需要检查计费结果。 remaining_credits 可以为负，如果不可用则为 null。该平衡会在操作完成时记录，并且可能会在其他请求同时运行时发生变化。

GET /使用是免费的。它返回 remaining_credits 和 expires_at。对于 IP 试用，它还返回 resets_at、limit 和 period_seconds。试用限制为10积分，期限为86400秒。对于 API 密钥帐户，这些仅限试用的字段为 null。 resets_at是试用重置时间，而不是订阅到期日期。

V1 和 v2 使用相同的贷方余额。 v1 和 v2 的同时余额更新可能会发生冲突。不要假设计费保证在两个版本中只发生一次。

```json
{
  "data": {
    "remaining_credits": 9,
    "expires_at": "2026-09-26T12:00:00.000Z",
    "resets_at": "2026-09-26T12:00:00.000Z",
    "limit": 10,
    "period_seconds": 86400
  },
  "meta": {
    "request_id": "11111111-1111-4111-8111-111111111111",
    "duration_ms": 12,
    "access": {
      "mode": "ip_trial",
      "reason": "api_key_missing"
    },
    "usage": {
      "charged_credits": 0,
      "remaining_credits": 9,
      "billing_status": "not_charged",
      "resets_at": "2026-09-26T12:00:00.000Z",
      "limit": 10,
      "period_seconds": 86400
    }
  }
}
```

## 检查当前余额

GET /api/v2/usage 是免费的，并且采用 Bearer 身份验证，没有查询参数。省略密钥将读取当前的 IP 试用限额。

在您的服务器上运行这些示例。将流程环境中的 GENDERAPI_API_KEY 设置为现有的 API 密钥。确认 meta.access.mode 是 api_key：无法识别的密钥可以回退到 IP 试用。

读取余额无需花费任何积分。它仍然计入请求速率限制。

HTTP 4xx 和 5xx JSON 响应保留错误主体并返回非零退出状态。重试前请检查 code、action 和 meta.usage.billing_status。

**cURL**

cURL 7.76+ 在 POSIX shell 中. 在终端中运行。

```bash
curl --silent --show-error --fail-with-body --max-time 30 \
  --request GET 'https://api.genderapi.io/api/v2/usage' \
  --header "Authorization: Bearer ${GENDERAPI_API_KEY:?Set GENDERAPI_API_KEY}"
```

**JavaScript / Node.js**

Node.js 22+；内置获取. 另存为example.mjs并运行node example.mjs。

```javascript
// Server-side Node.js. Save as example.mjs.
const apiKey = process.env.GENDERAPI_API_KEY;
if (!apiKey) throw new Error("Set GENDERAPI_API_KEY");

const response = await fetch("https://api.genderapi.io/api/v2/usage", {
  method: "GET",
  headers: {
    Authorization: `Bearer ${apiKey}`,
  },
  signal: AbortSignal.timeout(30_000),
  redirect: "error",
});
const raw = await response.text();
if (!(response.headers.get("content-type") ?? "").includes("json")) {
  throw new Error(`HTTP ${response.status}: expected JSON; request ID ${response.headers.get("x-request-id")}`);
}
const result = JSON.parse(raw); // Also accepts application/problem+json.
if (!response.ok) {
  console.error(`HTTP ${response.status}`, result);
  process.exitCode = 1; // A retry is a new operation; inspect billing first.
} else {
  console.log(JSON.stringify(result, null, 2));
  // For batches, inspect every item: HTTP 200 may contain item errors.
}
```

**Python**

Python 3.10+；标准库. 另存为example.py并运行python3 example.py。

```python
import json
import os
import sys
import urllib.error
import urllib.request

api_key = os.environ.get("GENDERAPI_API_KEY")
if not api_key:
    raise RuntimeError("Set GENDERAPI_API_KEY")

class NoRedirect(urllib.request.HTTPRedirectHandler):
    def redirect_request(self, req, fp, code, msg, headers, newurl):
        return None

request = urllib.request.Request(
    "https://api.genderapi.io/api/v2/usage",
    method="GET",
    headers={
        "Authorization": "Bearer " + api_key,
    },
)
opener = urllib.request.build_opener(NoRedirect())
try:
    response = opener.open(request, timeout=30)
except urllib.error.HTTPError as error:
    response = error  # Keep the Problem Details body on non-2xx responses.
with response:
    status = response.status
    raw = response.read().decode("utf-8")
    if "json" not in response.headers.get("Content-Type", ""):
        raise RuntimeError(f"HTTP {status}: expected a JSON response")
    result = json.loads(raw)
print(json.dumps(result, indent=2), file=sys.stderr if status >= 300 else sys.stdout)
if not 200 <= status < 300:
    sys.exit(1)  # Inspect code, action and billing before retrying.
# For batches, inspect every item even when HTTP status is 200.
```

**PHP**

PHP 8+ 带有 cURL 扩展. 另存为example.php并运行php example.php。

```php
<?php
$apiKey = getenv('GENDERAPI_API_KEY');
if (!$apiKey) {
    throw new RuntimeException('Set GENDERAPI_API_KEY');
}

$ch = curl_init('https://api.genderapi.io/api/v2/usage');
curl_setopt_array($ch, [
    CURLOPT_CUSTOMREQUEST => 'GET',
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_FOLLOWLOCATION => false,
    CURLOPT_TIMEOUT => 30,
    CURLOPT_HTTPHEADER => [
        'Authorization: Bearer ' . $apiKey,
    ],
]);
$raw = curl_exec($ch);
if ($raw === false) {
    throw new RuntimeException(curl_error($ch));
}
$status = curl_getinfo($ch, CURLINFO_HTTP_CODE);
$contentType = curl_getinfo($ch, CURLINFO_CONTENT_TYPE) ?: '';
curl_close($ch);
if (strpos($contentType, 'json') === false) {
    throw new RuntimeException("HTTP $status: expected a JSON response");
}
$result = json_decode($raw, true, 512, JSON_THROW_ON_ERROR);
$output = json_encode($result, JSON_PRETTY_PRINT | JSON_THROW_ON_ERROR) . PHP_EOL;
if ($status < 200 || $status >= 300) {
    fwrite(STDERR, $output); // Preserve the Problem Details body.
    exit(1);
}
echo $output;
// For batches, inspect every item; HTTP 200 can contain item errors.
```

**Java**

Java 17+；标准HTTP客户端. 另存为GenderApiExample.java并运行java GenderApiExample.java。

```java
import java.net.URI;
import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;
import java.nio.charset.StandardCharsets;
import java.time.Duration;

public class GenderApiExample {
    private static String requiredEnv(String name) {
        String value = System.getenv(name);
        if (value == null || value.isBlank()) throw new IllegalStateException("Set " + name);
        return value;
    }

    public static void main(String[] args) throws Exception {
        String apiKey = requiredEnv("GENDERAPI_API_KEY");
        HttpClient client = HttpClient.newBuilder()
            .connectTimeout(Duration.ofSeconds(10))
            .followRedirects(HttpClient.Redirect.NEVER)
            .build();
        HttpRequest request = HttpRequest.newBuilder(URI.create("https://api.genderapi.io/api/v2/usage"))
            .timeout(Duration.ofSeconds(30))
            .header("Authorization", "Bearer " + apiKey)
            .GET()
            .build();
        HttpResponse<String> response = client.send(request,
            HttpResponse.BodyHandlers.ofString(StandardCharsets.UTF_8));
        if (!response.headers().firstValue("content-type").orElse("").contains("json")) {
            throw new IllegalStateException("HTTP " + response.statusCode() + ": expected JSON");
        }
        // JSON text; parse with your application's JSON library when integrating.
        if (response.statusCode() < 200 || response.statusCode() >= 300) {
            System.err.println(response.body()); // Includes Problem Details.
            System.exit(1);
        }
        System.out.println(response.body());
        // For batches, inspect each item's data or error, including on HTTP 200.
    }
}
```

**C# / .NET**

.NET 8+ 控制台应用程序. 在控制台项目中用作 Program.cs，然后运行 dotnet run。

```csharp
using System;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Text;
using System.Text.Json;

string RequiredEnv(string name) =>
    !string.IsNullOrWhiteSpace(Environment.GetEnvironmentVariable(name))
        ? Environment.GetEnvironmentVariable(name)!
        : throw new InvalidOperationException($"Set {name}");

var apiKey = RequiredEnv("GENDERAPI_API_KEY");
using var handler = new HttpClientHandler { AllowAutoRedirect = false };
using var client = new HttpClient(handler) { Timeout = TimeSpan.FromSeconds(30) };
using var request = new HttpRequestMessage(HttpMethod.Get, "https://api.genderapi.io/api/v2/usage");
request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", apiKey);

using var response = await client.SendAsync(request);
var raw = await response.Content.ReadAsStringAsync();
if (!(response.Content.Headers.ContentType?.MediaType?.Contains("json") ?? false))
    throw new InvalidOperationException($"HTTP {(int)response.StatusCode}: expected JSON");
using var result = JsonDocument.Parse(raw);
if (!response.IsSuccessStatusCode)
{
    Console.Error.WriteLine(result.RootElement); // Preserve Problem Details.
    Environment.ExitCode = 1;
}
else
{
    Console.WriteLine(result.RootElement);
    // For batches, inspect every item even on HTTP 200.
}
```

**Go**

Go 1.22+；标准库. 另存为main.go并运行go run main.go。

```go
package main

import (
    "encoding/json"
    "fmt"
    "io"
    "net/http"
    "os"
    "strings"
    "time"
)

func requiredEnv(name string) string {
    value := os.Getenv(name)
    if value == "" { panic("Set " + name) }
    return value
}

func run() error {
    apiKey := requiredEnv("GENDERAPI_API_KEY")
    request, err := http.NewRequest("GET", "https://api.genderapi.io/api/v2/usage", nil)
    if err != nil { return err }
    request.Header.Set("Authorization", "Bearer " + apiKey)
    client := &http.Client{
        Timeout: 30 * time.Second,
        CheckRedirect: func(req *http.Request, via []*http.Request) error {
            return http.ErrUseLastResponse
        },
    }
    response, err := client.Do(request)
    if err != nil { return err }
    defer response.Body.Close()
    raw, err := io.ReadAll(response.Body)
    if err != nil { return err }
    if !strings.Contains(response.Header.Get("Content-Type"), "json") || !json.Valid(raw) {
        return fmt.Errorf("HTTP %d: expected a JSON response", response.StatusCode)
    }
    if response.StatusCode < 200 || response.StatusCode >= 300 {
        return fmt.Errorf("HTTP %d: %s", response.StatusCode, raw)
    }
    fmt.Println(string(raw))
    // For batches, inspect every item even on HTTP 200.
    return nil
}

func main() {
    if err := run(); err != nil {
        fmt.Fprintln(os.Stderr, err) // Keep Problem Details for error handling.
        os.Exit(1)
    }
}
