How is this different from consumer translation tools?

This is a REST API designed to run inside your application, not a copy-paste tool. You send JSON, you get JSON back — with the translated content in a predictable structure your code can rely on. You also control voice tone and pass domain context (for example product data or HR copy), which generic translators ignore.

How many languages does the Translation API support?

The API translates between 80+ languages, including all major European, Asian and Middle Eastern languages. You simply pass the target language name as a parameter of the POST request.

Does the API preserve formatting of the source text?

Yes. The translation engine keeps the structure of the source content — paragraphs, lists and inline markup — so translated e-commerce descriptions, emails or help articles drop straight back into your templates without manual cleanup.

What do the voice_tone and context parameters do?

voice_tone instructs the AI to keep a specific style (professional, funny, neutral, brand-specific phrasing), while context tells it what the text is (a product page, a job offer, a support reply). Both parameters make translations match your domain instead of sounding generic.

How does the asynchronous job workflow work?

Every POST request creates a translation job and immediately returns a status_url. Your application polls that URL (or uses one of our SDKs that poll for you) and receives the finished, structured JSON result — a pattern that scales cleanly for batch localization pipelines.

How much does the Translation API cost?

Pricing is subscription-based and starts at $50/month, with usage counted in processed words. Every new account gets a 14-day free trial with 100,000 words included — no credit card required.

How the Async Job Workflow Works

One pattern for every SharpAPI endpoint — built to survive batch localization jobs.

1. Submit

POST your content with target language, voice_tone and context. The API instantly returns a job ID and a status_url.

2. Poll

Poll the status_url (or let an SDK do it). Jobs are processed asynchronously in a queue — usually within seconds.

3. Consume JSON

Receive the translation as structured JSON with a stable schema, ready to store or render — no parsing heuristics.

Call it from any stack

Submit a job, poll the status URL, get structured JSON. SDKs available for PHP, Laravel, Python, Node.js, .NET and Flutter.

curl -X POST "https://sharpapi.com/api/v1/content/translate" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"content": "Free shipping on orders over $49. Returns accepted within 30 days.", "language": "Spanish", "voice_tone": "professional", "context": "E-commerce store policy page"}'

$response = Http::withToken('YOUR_API_KEY')
    ->post('https://sharpapi.com/api/v1/content/translate', {"content": "Free shipping on orders over $49. Returns accepted within 30 days.", "language": "Spanish", "voice_tone": "professional", "context": "E-commerce store policy page"});

$statusUrl = $response->json('status_url'); // poll until status = success

import requests

response = requests.post(
    "https://sharpapi.com/api/v1/content/translate",
    headers={"Authorization": "Bearer YOUR_API_KEY"},
    json={"content": "Free shipping on orders over $49. Returns accepted within 30 days.", "language": "Spanish", "voice_tone": "professional", "context": "E-commerce store policy page"},
)
status_url = response.json()["status_url"]  # poll until status == "success"

{
    "data": {
        "id": "5de4887a-0dfd-49b6-8edb-9280e468c210",
