The skill document

Ocr Pro

Convert and extract content from .pdf / images (.png/.jpg/.jpeg/.jp2/.webp/.gif/.bmp) using MinerU (mineru-open-api).

Install

npm install -g mineru-open-api
# or via Go (macOS/Linux):
go install github.com/opendatalab/MinerU-Ecosystem/cli/mineru-open-api@latest

Quick Start

# Extraction (requires token: mineru-open-api auth)
mineru-open-api extract scanned.pdf -o ./out/

# From URL
mineru-open-api extract https://example.com/scanned.pdf -o ./out/

# Specify language
mineru-open-api extract scanned.pdf --language en -o ./out/

Authentication

Token required for extract and crawl:

mineru-open-api auth            # Interactive token setup
export MINERU_TOKEN="your-token" # Or via environment variable

Create token at: https://mineru.net/apiManage/token

Capabilities

  • Supports local files and URLs
  • Requires token (mineru-open-api auth or MINERU_TOKEN env)
  • Supported input: .pdf / images (.png/.jpg/.jpeg/.jp2/.webp/.gif/.bmp)
  • Language hint with --language (default: ch, use en for English)
