# Introduction

> MinerU – The SOTA open-source PDF parsing model, as a production-ready API.

## What is ParseRouter?

ParseRouter turns documents — PDFs and images — into clean, structured output through [MinerU](https://github.com/opendatalab/MinerU) the state-of-the-art open-source document parsing model, served as a production-ready API.

You don't run GPUs, manage model weights, or stitch together OCR pipelines. You send a file, you get back Markdown and structured blocks. And unlike a typical parsing endpoint, you always know **exactly which model** processed your document — at a **flat, per-page price**. No black boxes.

## Why ParseRouter?

## How it works

1. **Get an API key** from your dashboard (`sk-pr-…`).
2. **Upload a document** to the parse endpoint as multipart form data.
3. **Receive structured output** – Markdown plus per-page blocks (titles, paragraphs, tables, and more).

```bash theme={null}
curl -X POST https://api.parserouter.com/v1/mineru/parse \
  -H "Authorization: Bearer sk-pr-..." \
  -F "file=@invoice.pdf" \
  -F "model=mineru2.5-pro-2605"
```
