Traduci testo
Tradurre il testo in un'unica lingua di destinazione.
POST https://api.translateapi.ai/api/v1/translate/
Organo di richiesta
| Parametro | Tipo | Richiesto | Designazione delle merci |
|---|---|---|---|
text |
string | Sì | Testo da tradurre (max 50.000 caratteri) |
target_language |
string | Sì | Target language code (e.g., "es", "fr", "de") |
source_language |
string | No. | Source language code. Default: "auto" (auto-detect) |
engine |
string | No. | Translation engine: "auto" (default), "huggingface", or "madlad". See Translation Models. Modelli di traduzione. |
* Uso target_language (stringa) per la lingua unica o target_languages (array) per multipli. Vedi Traduzione multi-target.
Risposta
{

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

"translation_time": 0.45
}
source_language or set it to "auto" to automatically detect the source language. The detected language is returned in the source_language response field.
Traduzione multi-target
Tradurre il testo in più lingue in una singola richiesta. Usa lo stesso endpoint della traduzione singola.
POST https://api.translateapi.ai/api/v1/translate/
Organo di richiesta
{
"text": "Hello, world!",
"target_languages": ["es", "fr", "de", "ja"],
"source_language": "en"
}
Uso target_languages (array) invece di target_language Per bersagli multipli.
Risposta

"translations": {
"es": "Hola, mundo!",
"fr": "Bonjour, monde!",
"de": "Hallo, Welt!",
"ja": "こんにちは、世界!"
},

Real-Time Progress Tracking
| Field | Designazione delle merci |
|---|---|
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). |

Parametri di richiesta
| Parametro | Tipo | Richiesto | Designazione delle merci |
|---|---|---|---|
texts |
array | Sì | Array di stringhe da tradurre |
target_language |
string | Sì | Codice della lingua di destinazione per la lingua unica |
target_languages |

string | No. | Source language code. Default: "auto" |
* Fornire sia target_language oppure target_languages, non tutte e due.
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.

Submit Corrections
Suggest a better translation for a given source text. Corrections enter a moderation queue; once approved by our team they surface as "Community Verified" translations for that text.
https://translateapi.ai/api/v1/ (not the api. translation host), and requires an API key.POST https://translateapi.ai/api/v1/suggestions/
Organo di richiesta
| Parameter | Tipo | Designazione delle merci |
|---|---|---|
source_text |
string | The original text that was translated. |
source_language |
string | Source language code (e.g. "en"). |
target_language |
string | Target language code (e.g. "es"). |
machine_translation |
string | The machine translation you are correcting. |
suggested_translation |
string | Your improved translation (must differ from machine_translation). |
Example Request
curl -X POST https://translateapi.ai/api/v1/suggestions/ \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"source_text": "Hello, world!",
"source_language": "en",

}'
Risposta
{
"id": 4213,
"status": "pending",
"created": true,

}
Re-submitting the same source/language pair updates your existing suggestion instead of creating a duplicate (returns 200 with "created": false).
Modelli di traduzione
Utilizziamo modelli di traduzione open source all'avanguardia in esecuzione sulla nostra infrastruttura GPU. Tutti i modelli sono in licenza commerciale (Apache 2.0).
| Modello | Lingue | Meglio per |
|---|---|---|
| Helsinki-NLP/opus-mt | 50+ coppie di lingue | Lingue comuni (EN, ES, FR, DE, IT, PT, RU, ZH, JA, ecc.) |
| Google MADLAD-400 | 400+ lingue | Lingue rare, copertura completa |
L'API seleziona automaticamente il modello migliore per la coppia linguistica. È possibile specificare opzionalmente un engine parametro:
| Motore | Designazione delle merci |
|---|---|
"auto" |
Predefinito. Prova prima HuggingFace, rientra in MADLAD-400 |
"huggingface" |
Forza HuggingFace/MarianMT (più veloce, 50+ lingue) |
"madlad" |
Forza MADLAD-400 (400+ lingue) |
Gestione degli errori
L'API utilizza codici di stato HTTP standard per indicare il successo o il fallimento.
| Codice | Designazione delle merci |
|---|---|
| 200 | Successo |
| 202 | Accepted — Batch job queued successfully |
| 400 | Bad Request — Invalid parameters (missing text, unsupported language, etc.) |
| 401 | Non autorizzato - Chiave API non valida o mancante |
| 402 | Payment Required — Character credits exhausted. Upgrade your plan or purchase a top-up. |
| 403 | Forbidden — API key lacks required scope or IP not in whitelist |
| 503 | Servizio Non disponibile - Motore di traduzione temporaneamente inattivo |
Formato di risposta dell'errore
{
"error": "insufficient_credits",
"credits_remaining": 0
}
Usage Limits
TranslateAPI has no request rate limits. All requests are queued and processed by our auto-scaling GPU cluster. Your plan determines your monthly character allowance:

Quando supererai il tuo limite, riceverai un 402 Payment Required risposta fino al mese successivo o si aggiorna.
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.
