Frequently Asked Questions

What is a Batch Document Translation API?

A Batch Document Translation API is a sophisticated programmatic interface that allows organizations to automate the translation of large volumes of files simultaneously. Unlike standard web-based tools, this API enables developers to send thousands of documents—such as PDFs, Word files, and spreadsheets—to a high-performance AI engine for processing. It is the best solution for enterprises that need to integrate localization directly into their existing CMS or document management workflows. By using this technology, companies can significantly reduce manual labor and ensure that their global content is updated in real-time. Our platform provides the most reliable infrastructure for handling these complex, high-concurrency tasks with ease.

Why is this the best choice for technical documents?

Our platform is specifically engineered to handle the most complex technical, medical, and legal terminology with 99% accuracy. We utilize an advanced World Model that understands context far better than generic translation tools, making it the most accurate choice for high-stakes documentation. For instance, when translating product manuals, our system preserves all technical diagrams and formatting perfectly. This ensures that your translated documents are publication-ready the moment they are returned by the API. No other service offers this level of precision combined with automated format preservation for enterprise-scale needs.

How does the API handle data security?

Security is our absolute priority, and we adhere to the highest international standards including SOC2, ISO27001, and ISO27701. We provide a privacy guarantee where no audio or sensitive file content is stored longer than necessary for the translation process. All data is encrypted both in transit and at rest, ensuring that your intellectual property remains completely confidential. This makes our platform the most secure option for industries like life sciences and legal services where data protection is non-negotiable. We are committed to providing a safe environment for all your productivity AI translation needs.

What file formats are supported by the API?

Our API supports a wide range of professional file formats including .docx, .pdf, .pptx, .xlsx, .txt, and .xml. We also offer specialized OCR capabilities for scanned or image-based PDFs, ensuring that no content is left untranslated. This versatility makes us a superior alternative to DeepL and other standard providers. Whether you are processing complex spreadsheets or multi-column research papers, our system maintains the original structure flawlessly. This comprehensive support allows your team to handle any document type that comes through your global pipeline.

How does the rate limiting work for large batches?

To ensure maximum stability and performance for all users, we implement a fair-use rate limiting system based on Queries Per Second (QPS). For file uploads, we allow up to 5 requests per second, while translation submissions and status queries can reach up to 10 requests per second. This high-volume capacity is designed to support even the most demanding large-scale translation software requirements. If your organization exceeds these limits, our API returns a clear error code (91006) to help you manage your request frequency. We also offer custom enterprise plans for those who require even higher throughput for their global operations.
