## Product facts

- Supported document formats: PDF, DOCX, PPTX, and XLSX.
- The REST API uses an asynchronous submit, poll, and download workflow.
- The remote MCP integration can check credits, create translation tasks, poll progress, and download results from compatible AI clients.
- The API, MCP integration, and web workspace use a shared credits balance.
- API and MCP document translation is charged at 1,500 credits per billable page.
- PDF billing uses physical pages, PPTX uses slides, DOCX uses embedded page count with a one-page fallback, and XLSX uses worksheets.
- For a local file larger than 20 MB, use the REST API upload workflow instead of MCP.
- Layout retention depends on source quality, document structure, scans, images, and formatting complexity. Users should review translated output before delivery.

## Pricing summary

- New users receive 5,000 trial tokens for web-workspace testing.
- Individual web users can pay as needed and use single-document billing without a subscription.
- Ordinary text documents are approximately CNY 0.10 per page; scans, images, and complex layouts can cost more.
- Enterprise localization and long-running team workflows are quoted after requirements are reviewed.
