req.Header.Set("Authorization", "Bearer YOUR_API_KEY")
req.Header.Set("Content-Type", "application/json")

resp, _ := http.DefaultClient.Do(req)
defer resp.Body.Close()

var result map[string]interface{}
json.NewDecoder(resp.Body).Decode(&result)
fmt.Println(result["translated_text"])  // "Hola, mundo!"
var client = new HttpClient();
client.DefaultRequestHeaders.Add("Authorization", "Bearer YOUR_API_KEY");

var content = new StringContent(
    JsonSerializer.Serialize(new {
        text = "Hello, world!",
        target_language = "es"
    }),
    Encoding.UTF8,

翻译文本

将文本翻译为单一目标语言 。

POST https://api.translateapi.ai/api/v1/translate/
请求机构
参数 类型 所需 说明
text string 是 是 要翻译的文本 (最多 50,000 个字符)
target_language string 是* Target language code (e.g., "es", "fr", "de")
source_language string 否 无 Source language code. Default: "auto" (auto-detect)
engine string 否 无 Translation engine: "auto" (default), "huggingface", or "madlad". See Translation Models. 翻译模型.

* 使用 target_language 单语或单语(字符串),或 target_languages 多重 (数组) 。 见 多目标翻译.

响应
{
    "translated_text": "Hola, mundo!",
    "source_language": "en",
    "target_language": "es",
    "translations": {
        "es": "Hola, mundo!"
    },

    "translation_time": 0.45
}
Auto-Detection: Omit source_language or set it to "auto" to automatically detect the source language. The detected language is returned in the source_language response field.

多目标翻译

在单一请求中将文本翻译为多种语言。 使用与单一翻译相同的端点 。

POST https://api.translateapi.ai/api/v1/translate/
请求机构
{
    "text": "Hello, world!",
    "target_languages": ["es", "fr", "de", "ja"],
    "source_language": "en"
}

使用 target_languages (阵列)而不是 target_language (string) 针对多个目标。

响应
{
    "source_language": "en",
    "translations": {
        "es": "Hola, mundo!",
        "fr": "Bonjour, monde!",
        "de": "Hallo, Welt!",
        "ja": "こんにちは、世界!"
    },
    "character_count": 52,
    "translation_time": 2.31
}
提示 : 您可以在一次请求中翻译多达50种语言。

批批次翻译

立即翻译多个文本并进行同步处理。 提交批次和民意测验结果 。

Limits: Max 100 texts per batch, max 300 total items (texts × target languages). Jobs time out 45 minutes after processing starts.
Speed: Common languages (ES, FR, DE) use fast models (~0.1s/text). Less common languages use our multilingual model (~1-3s/text).
POST https://api.translateapi.ai/api/v1/translate/batch/

Real-Time Progress Tracking
Field 说明
status pending (queued, waiting for a GPU worker), processing (actively translating), completed, failed
processed_texts Number of individual translations completed so far. Updates in real time as each text is translated.
progress_percentage Completion percentage (0-100). Calculated from processed_texts / total_texts.
queue_position Your position in the queue when status is "pending" (1 = next up). Null when processing or completed. Use this to estimate wait time and show queue status to your users.
processing_time Total processing time in seconds (available when completed).
多语言批次

{
    "texts": ["Hello", "Goodbye"],
    "target_languages": ["es", "fr"],
    "source_language": "en"
}
已完成结果_ 数据

        {"es": "Adiós", "fr": "Au revoir"}
    ],
    "source_language": "en",
    "target_languages": ["es", "fr"],
    "character_count": 24,
    "processing_time": 2.45
}
请求参数
参数 类型 所需 说明
texts array 是 是 要翻译的字符串排列
target_language string 是* 单一语言目标语言代码
target_languages array 是* 多种语文目标语言代码的排列
source_language string 否 无 Source language code. Default: "auto"

* 提供 target_languagetarget_languages不是两者兼而有之

Best Practices for Large Workloads
  • Send 1 target language per batch request. This keeps each batch fast and makes progress easy to track.
  • Keep batches at 50-100 texts. Smaller batches complete faster and give you more frequent progress updates.
  • Submit as many batch jobs as you need — our GPU cluster auto-scales to handle demand. Jobs are processed in parallel across multiple instances.
  • On timeout, re-poll the same job_id instead of submitting a new batch. The original job may still be processing on the GPU.
  • Poll every 3-5 seconds. More frequent polling does not speed up processing.

在保存格式的同时翻译整个文档。 支持多个文件格式 。

POST https://api.translateapi.ai/api/v1/translate/document/
请求(多部分/格式数据)

Auto-Scaling Cloud Infrastructure

TranslateAPI runs on dedicated NVIDIA A100 GPU instances with automatic horizontal scaling. When demand increases, additional GPU instances are launched within minutes to maintain fast response times. All requests are queued and processed — send hundreds of concurrent requests and they'll all be handled. Real-time translations get priority, batch jobs process in the background.
