Dokumentatioun
D'Integratioun vun de verschiddenen Applikatiounen an der REST API ass ganz einfach.
Erfuerschung
D' TranslateAPI bitt eng einfach REST Interface fir Text tëscht 180+ Sproochen ze iwwersetzen. All API Endpunkte ginn JSON Äntwerten zréck.

|---|---|---|---|
text |
string | Ja | Text ze iwwersetzen (maximal 50. 000 Zeichen) |

source_language or set it to "auto" to automatically detect the source language. The detected language is returned in the source_language response field.
Multi-Target Iwwersetzung
Iwwersetzt Text a méi Sproochen an enger eenzeger Ufro. Benotzt de selwechten Endpunkt wéi eng eenzeg Iwwersetzung.

Ufrokörper
{
"text": "Hello, world!",
"target_languages": ["es", "fr", "de", "ja"],
"source_language": "en"
}
Verwenden target_languages (Array) anstatt target_language (String) fir méi Zieler.
Äntwert

Real-Time Progress Tracking
| Field | Beschreiwung |
|---|---|
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). |
Multi-Language Batch
Méi Texter a méi Sproochen op eemol iwwersetzen:
{
"texts": ["Hello", "Goodbye"],
"target_languages": ["es", "fr"],
"source_language": "en"
}
Completed result_data

"processing_time": 2.45
}
Parameter ufroen
| Parameter | Typ | Erfuerderlech | Beschreiwung |
|---|---|---|---|
texts |
array | Ja | Array of strings to translate |
target_language |
string | Ja* | Zielsproochcode fir eng eenzeg Sprooch |
target_languages |
array | Ja* | Array vu Zilsproochcode fir verschidde Sproochen |
source_language |
string | Nee | Source language code. Default: "auto" |
* Gitt entweder target_language oder target_languages, net béid.
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.

Re-submitting the same source/language pair updates your existing suggestion instead of creating a duplicate (returns 200 with "created": false).
Iwwersetzungsmodell
Mir benotze state-of-the-art Open Source Iwwersetzungsmodeller déi op eiser eegene GPU Infrastruktur lafen. All Modeller sinn kommerziell lizenzéiert (Apache 2.0).
| Modell | Sproochen | Bescht fir |
|---|---|---|
| Helsinki-NLP/opus-mt | Lëscht vu lëtzebuergeschen Dichter | D'Lëtzebuerger Sprooch (Lëtzebuergesch, Däitsch, Franséisch, Italienesch, Spuenesch, Russesch, etc.) |
| Google MADLAD-400 | 400 Sproochen | Lëscht vu lëtzebuergesche Sproochen |
D'API wielt automatesch dat bescht Modell fir Äert Sproochpaar aus. Dir kënnt optional e spezifizéieren engine Parameter:
| Motor | Beschreiwung |
|---|---|
"auto" |
Standard. Probéiert HuggingFace als éischt, geet zréck op MADLAD-400 |
"huggingface" |
Force HuggingFace/MarianMT (schnellst, 50+ Sproochen) |
"madlad" |
Mäerz 1940 (400 Säiten). |

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.
