Authentication

Before using, configure your API token (get one from https://mineru.net):

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

Token resolution order: --token flag > MINERU_TOKEN env > ~/.mineru/config.yaml.

Supported input formats

The extract command accepts the following input types:

• PDF (.pdf) — primary use case, supports scanned and digital PDFs
• Images (.png, .jpg, .jpeg, .webp, .gif,.bmp) — use --ocr for best results on scanned content
• DOCX (.docx) — Microsoft Word documents
• URLs — remote files are downloaded automatically

The crawl command accepts any HTTP/HTTPS URL and extracts web page content.

Default behavior

• Table recognition: ON by default. Tables in documents are extracted and converted to Markdown tables. Use --no-table to disable.
• Formula recognition: ON by default. Mathematical formulas are extracted as LaTeX. Use --no-formula to disable.
• Language: defaults to ch (Chinese). Use --language en for English documents.
• Model: auto-selected. Use --model vlm for complex layouts, --model pipeline for speed.

Quick start

mineru extract report.pdf                    # PDF → Markdown to stdout
mineru extract report.pdf -o ./out/          # Save to file
mineru extract report.pdf -f md,docx         # Multiple formats
mineru crawl https://example.com/article     # Web page → Markdown

Core workflow

1. Authenticate: mineru auth or set MINERU_TOKEN
2. Extract: mineru extract <file-or-url> for documents
3. Crawl: mineru crawl <url> for web pages
4. Check results: output goes to stdout (default) or -o directory

Commands

extract — Document extraction

Convert PDFs, images, and other documents to Markdown or other formats.

mineru extract report.pdf                         # Markdown to stdout
mineru extract report.pdf -f html                 # HTML to stdout
mineru extract report.pdf -o ./out/               # Save to directory
mineru extract report.pdf -o ./out/ -f md,docx    # Multiple formats
mineru extract *.pdf -o ./results/                # Batch extract
mineru extract --list files.txt -o ./results/     # Batch from file list
mineru extract https://example.com/doc.pdf        # Extract from URL
cat doc.pdf | mineru extract --stdin -o ./out/    # From stdin

extract flags

crawl — Web page extraction

Fetch web pages and convert to Markdown.

mineru crawl https://example.com/article              # Markdown to stdout
mineru crawl https://example.com/article -f html      # HTML to stdout
mineru crawl https://example.com/article -o ./out/     # Save to file
mineru crawl url1 url2 -o ./pages/                     # Batch crawl
mineru crawl --list urls.txt -o ./pages/               # Batch from file list

crawl flags

auth — Authentication management

mineru auth              # Interactive token setup
mineru auth --verify     # Verify current token is valid
mineru auth --show       # Show current token source and masked value

status — Async task status

Query the status of a previously submitted extraction task.

mineru status <task-id>                      # Check status once
mineru status <task-id> --wait               # Wait for completion
mineru status <task-id> --wait -o ./out/     # Wait and download results
mineru status <task-id> --wait --timeout 600 # Custom timeout

status flags

version — Version info

mineru version    # Show version, commit, build date, Go version, OS/arch

Global flags

These flags apply to all commands:

Output behavior

• No -o flag: result goes to stdout; status/progress messages go to stderr
• With -o flag: result saved to file/directory; progress messages on stderr
• Batch mode: requires -o to specify output directory
• Binary formats (docx): cannot output to stdout, must use -o
• Markdown output includes extracted images saved alongside the .md file

Examples

Single PDF extraction

mineru extract report.pdf -o ./output/
# Output: ./output/report.md + ./output/images/

Extract with OCR and specific pages

mineru extract scanned.pdf --ocr --pages "1-5" -o ./out/

Multi-format output

mineru extract paper.pdf -f md,html,docx -o ./out/
# Output: ./out/paper.md, ./out/paper.html, ./out/paper.docx

Batch processing from file list

# files.txt contains one path per line
mineru extract --list files.txt -o ./results/

Extract to LaTeX

mineru extract paper.pdf -f latex -o ./out/
# Output: ./out/paper.tex

English document with specific language

mineru extract english-report.pdf --language en -o ./out/

Extract Word document to Markdown

mineru extract resume.docx -o ./out/
# Output: ./out/resume.md

Pipe workflow

# Download and extract in one pipeline
curl -sL https://example.com/doc.pdf | mineru extract --stdin --stdin-name doc.pdf

Web crawling

mineru crawl https://example.com/docs/guide -o ./docs/

Batch crawl with URL list

echo -e "https://example.com/page1\
https://example.com/page2" | mineru crawl --stdin-list -o ./pages/

Use with other tools

# Extract and pipe to another tool
mineru extract report.pdf | wc -w              # Word count
mineru extract report.pdf | grep "keyword"     # Search content
mineru extract report.pdf -f json | jq '.[]'   # Parse structured output

Agent guidelines

When using this skill on behalf of the user:

• Always ask for the file path if the user didn't specify one. Never guess or fabricate a filename.
• Quote file paths that contain spaces or special characters with double quotes in commands. Example: mineru extract "report 01.pdf", NOT mineru extract report 01.pdf.
• Don't run commands blindly on errors — if the user asks "提取失败了怎么办", explain the exit code and troubleshooting steps instead of re-running the command.
• Installation questions ("mineru 怎么安装") should be answered with the install instructions, not by running mineru extract.
• DOCX as input is supported — if the user asks "这个 Word 文档能转 Markdown 吗", use mineru extract file.docx.
• Table extraction — tables are extracted by default as part of the Markdown output. There is no "tables only" mode; the full document is always extracted.
• For stdout mode (no -o), only one text format can be output at a time. If the user wants multiple formats, suggest adding -o.

Default output directory

When the user does NOT specify an output path (-o), the agent MUST generate a default output directory to prevent file overwrites. Use:

~/MinerU-Skill/<name>_<hash>/

Naming rules:

• <name>: derived from the source, then sanitized for safe directory names.

- For URLs: last path segment (e.g. https://arxiv.org/pdf/2509.22186 → 2509.22186) - For local files: filename without extension (e.g. report.pdf → report) - Sanitization: replace spaces and shell-unsafe characters (space, (, ), [, ], &, ', ", !, #, $, ` `) with _. Collapse consecutive _ into one. Keep alphanumeric, -, _, .`, and CJK characters.

• <hash>: first 6 characters of the MD5 hash of the full original source path or URL (before sanitization). This ensures:

- Different URLs with similar basenames get unique directories - Re-running the same source reuses the same directory (idempotent)

Examples:

How the agent should generate the hash:

echo -n "https://arxiv.org/pdf/2509.22186" | md5sum | cut -c1-6

Or on macOS:

echo -n "https://arxiv.org/pdf/2509.22186" | md5 | cut -c1-6

When the user specifies -o: use the user's path as-is, do NOT override with the default directory.

Exit codes

Troubleshooting

• "no API token found": Run mineru auth or set MINERU_TOKEN env variable
• Timeout on large files: Increase with --timeout 600 (seconds)
• Batch fails partially: Check stderr for per-file status; succeeded files are still saved
• Binary format to stdout: Use -o flag; docx cannot stream to stdout
• Private deployment: Use --base-url https://your-server.com/api
• Extraction quality is poor: Try --model vlm for complex layouts, or --ocr for scanned documents
• Formula not recognized: Ensure --no-formula is NOT set; try --model vlm for better formula support

Notes

• All status/progress messages go to stderr; only document content goes to stdout
• Batch mode automatically polls the API with exponential backoff
• Token is stored in ~/.mineru/config.yaml after mineru auth
• The CLI wraps the MinerU Open SDK (github.com/OpenDataLab/mineru-open-sdk)
