API Documentation

Integrate powerful translation into your applications with our simple REST API.

Getting Started

Bidh an TranslateAPI a' toirt eadar-aghaidh REST sìmplidh dhut airson teacsa eadar 180+ cànan a thionndadh. Bidh freagairtean JSON air ais aig gach ceann-phuing API.

1. Get Your API Key

Create a free account and generate your API key from the dashboard:

  1. Sign up at translateapi.ai/signup
  2. Go to Dashboard → API Keys
  3. Click "Create API Key" and copy your key

API keys start with ta_ followed by 56 hex characters.

Bun-URL: https://api.translateapi.ai/api/v1/
2. Make Your First Request

Replace YOUR_API_KEY with the key from your dashboard:

Batch Translation

Translation multiple texts at once with async processing. Submit a batch and poll for results.

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).

Real-Time Progress Tracking
Field Cur-seachad
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).

Paramadairean iarrtais
Paramadair Seòrsa Riatanas Cur-seachad
texts array Tha Sreath de shreathan ri eadar-theangachadh
target_language string Tha* Còd na cànain-targaid airson cànan singilte
target_languages array Tha* Array of target language codes for multiple languages
source_language string Chan eil Source language code. Default: "auto"

* Cuir an dàrna cuid target_language no target_languages, chan e an dà chuid.

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.

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:

Plana Characters/Month Batch API Documents Praghas

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.
