Real-Time Progress Tracking
| Field | Priskribo |
|---|---|
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). |

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).
Tradukado
Ni uzas la plej modernajn malfermkodajn tradukajn modelojn funkciantajn sur nia propra GPU-infrastrukturo. Ĉiuj modeloj estas komerce licencitaj (Apache 2.0).
| & Modelo: | Lingvoj | Plej bona por |
|---|---|---|
| Helsinki-NLP/opus-mt | 50+ lingvoparoj | Komunaj lingvoj (EN, ES, FR, DE, IT, PT, RU, ZH, JA, ktp.) |
| Google MADLAD-400 | 400+ lingvoj | Raraj lingvoj, ampleksa kovro |
La API aŭtomate elektas la plej bonan modelon por via lingva paro. Vi povas opcione doni engine parametro:
| Motoro | Priskribo |
|---|---|
"auto" |

"madlad" |
Force MADLAD-400 (pli ol 400 lingvoj) |
Erarotraktado
La API uzas standardajn HTTP-statusajn kodojn por indiki sukceson aŭ malsukceson.
| Kodo | Priskribo |

| 202 | Accepted — Batch job queued successfully |
| 400 | Bad Request — Invalid parameters (missing text, unsupported language, etc.) |
| 401 | Neaŭtorizita - Nevalida aŭ mankanta API- ŝlosilo |
| 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 |

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:
| Plano | Signoj/monato | Batch API | Documents | Prezo | |

Kiam vi superos vian limigon, vi ricevos 402 Payment Required respondo ĝis la venonta monato aŭ vi ĝisdatigos.
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.
