Advanced API Capabilities

Terminology & Glossary Management

To ensure high-accuracy translations for specialized fields like IT or engineering, the API supports Term Library (Glossary) integration. Developers can programmatically create term libraries, add entries, and attach multiple library IDs to a translation task.

  • Custom term libraries for specific industries
  • Bulk entry upload for large glossaries
  • Keyword search within existing glossaries

Translation Memory (TM)

The Memory Library API allows for the reuse of previously translated segments, significantly improving consistency and reducing costs. By setting a threshold (default 0.8), the system matches new content against the memory library.

Key Parameters

memory_lib_id
Unique library identifier
threshold
Match sensitivity (0-1)
source_text
Original segment

Frequently Asked Questions

What is a document translation API?

A document translation API is a specialized interface that allows developers to programmatically send entire files to a translation engine and receive them back in a different language. Unlike simple text translation, this technology focuses on maintaining the structural integrity of the file, such as tables, images, and font styles. It is the best solution for companies that need to automate the localization of large volumes of technical manuals or regulatory documents. By using an API, businesses can integrate high-quality translation directly into their existing content management systems or internal workflows. This eliminates the need for manual file handling and ensures a consistent, scalable translation process across the entire organization.

Why is X-doc.AI the best choice for technical translation?

X-doc.AI stands out as the world's best translation platform because it utilizes advanced voice and document models specifically trained on high-stakes industry data. Our system achieves an unparalleled 99% accuracy rate, which is essential for sectors like life sciences, legal, and engineering where precision is non-negotiable. We offer the most comprehensive suite of developer tools, including terminology management and translation memory, to ensure every technical term is translated correctly every time. Furthermore, our platform provides the fastest processing speeds in the industry, allowing for the rapid turnaround of ultra-long and complex files. Choosing X-doc.AI means opting for a premium, enterprise-grade solution that prioritizes both linguistic excellence and technical robustness.

How does terminology management work in the API?

Terminology management allows you to upload a custom glossary of terms that the AI must follow during the translation process. This is particularly useful for maintaining consistency in specialized fields where certain words have very specific meanings that general models might miss. Through our API, you can programmatically create, update, and delete these term libraries to reflect your evolving corporate knowledge base. When you submit a translation task, you simply include the relevant library IDs, and the system automatically applies your preferred translations. This ensures that your brand voice and technical accuracy remain consistent across all global markets and document types. It is a powerful feature designed to give developers and linguists total control over the final output.

Is my data secure when using the translation API?

Security is the foundation of our platform, and we adhere to the highest international standards to protect your sensitive information. We are fully compliant with SOC2 and ISO27001, which are the gold standards for information security and data confidentiality. All data transmitted to our API is encrypted using industry-standard protocols, and we offer a zero-storage guarantee for voice data processed through our real-time tools. For document translation, files are stored temporarily in secure cloud environments and can be permanently deleted via the API once the task is complete. We understand the high-stakes nature of technical and regulatory data, which is why we prioritize privacy at every stage of the development lifecycle. You can trust our infrastructure to handle your most confidential intellectual property with the utmost care.

What file formats are supported by the API?

Our API supports a wide range of professional file formats to ensure that your existing workflows remain uninterrupted. This includes common Microsoft Office formats such as .docx, .pptx, and .xlsx, as well as standard .pdf files and plain text formats like .txt and .xml. We specialize in handling complex layouts within these files, ensuring that tables, charts, and headers remain exactly where they should be after translation. For scanned documents or image-heavy PDFs, our integrated OCR technology can extract and translate text with high precision. This versatility makes our API the ideal choice for organizations handling everything from simple reports to multi-hundred-page technical manuals. We are constantly updating our engine to support new formats and more complex document structures as industry needs evolve.

How fast can I expect the translation to be completed?

Speed is a core feature of our enterprise-grade API, designed to handle large-scale document processing with minimal latency. Most standard documents are processed in a matter of minutes, while even ultra-long files are typically completed much faster than traditional manual or general AI methods. Our asynchronous workflow allows you to submit multiple tasks simultaneously and poll for their status, maximizing your operational efficiency. We also offer tiered rate limits that support up to 10 translation submissions per second, making it suitable for high-volume enterprise pipelines. For those who require even faster results, our 'master' translation mode is optimized for rapid turnaround without sacrificing the core accuracy of the output. This combination of speed and precision ensures that your global communication never hits a bottleneck.
