# Document Processing

Gradio demo with two tabs sharing one Bearer API key from the environment.

## Tabs

| Tab | Gateway | Notes |
|-----|---------|--------|
| **Smart Doc** | `https://connect.zhihuiya.com/rd-llm/v1/documents/doc_parsing` | Multipart upload · `output_format=both` · **10 MB** max |
| **Translation** | `https://connect.zhihuiya.com/hiro_translation` | `stream`: SSE via `POST /translate`; `fast`: async submit + poll (`POST /translate/async` → `GET /translate/async/{taskId}`) |

## Auth

Set under Space **Settings → Variables / Secrets** (or local env):

1. `HIRO_API_KEY` (preferred)
2. else `RD_LLM_API_KEY`

No API key field in the UI.

## Files

| File | Purpose |
|------|---------|
| `app.py` | Gradio UI (tabs + streaming translation + document parse) |
| `api_client.py` | HTTP clients for translation + Smart Doc |
| `requirements.txt` | Python dependencies (`requests`; Gradio is pre-installed on Spaces) |

## Local run

```bash
pip install -r requirements.txt
export HIRO_API_KEY="sk-..."   # or RD_LLM_API_KEY
python app.py
```
