🔧 Requirements

Required Environment Variables

Scripts automatically read MinerU Token from environment variables (choose one):

# Option 1: Set MINERU_TOKEN
export MINERU_TOKEN="your_api_token_here"

# Option 2: Set MINERU_API_KEY
export MINERU_API_KEY="your_api_token_here"

Required Command-Line Tools

curl - For HTTP requests (usually pre-installed)
unzip - For extracting results (usually pre-installed)

Optional Tools

jq - For enhanced JSON parsing and security (recommended but not required)
- If not installed, scripts will use fallback methods
- Install: apt-get install jq (Debian/Ubuntu) or brew install jq (macOS)

Optional Configuration

# Set API base URL (default is pre-configured)
export MINERU_BASE_URL=
