PaddleOCR Document Parsing — AMD Radeon Cloud Edition

FREE PaddleOCR-VL 1.5 document parsing, powered by AMD Radeon Cloud. No API key required.

This skill extracts structured Markdown/JSON from PDFs and document images using PaddleOCR-VL 1.5 running on AMD Radeon Cloud — completely free, with no authentication or token needed.

Security Notice

• This skill does not read or transmit any API keys or tokens. The Radeon Cloud endpoint is free and requires no authentication.
• By default, results are printed to stdout. Use --output to save to a file when needed. No temporary files are created unless you explicitly choose to save.

When to Use This Skill

Trigger keywords (routing): Bilingual trigger terms (Chinese and English) are listed in the YAML description above — use that field for discovery and routing.

Use this skill for:

• Documents with tables (invoices, financial reports, spreadsheets)
• Documents with mathematical formulas (academic papers, scientific documents)
• Documents with charts and diagrams
• Multi-column layouts (newspapers, magazines, brochures)
• Complex document structures requiring layout analysis
• Any document requiring structured understanding

Do not use for:

• Simple text-only extraction
• Quick OCR tasks where speed is critical
• Screenshots or simple images with clear text

Installation

Scripts declare their dependencies inline (PEP 723). No separate install step is needed — uv resolves dependencies automatically:

uv run scripts/layout_caller.py --help

How to Use This Skill

> Working directory: All uv run scripts/... commands below should be run from this skill's root directory (the directory containing this SKILL.md file).

Basic Workflow

1. Identify the input source:
   - User provides URL: Use the --file-url parameter
   - User provides local file path: Use the --file-path parameter

2. Execute document parsing:

bash uv run scripts/layout_caller.py --file-url "URL provided by user" --pretty

Or for local files:

bash uv run scripts/layout_caller.py --file-path "file path" --pretty

Optional: explicitly set file type:

bash uv run scripts/layout_caller.py --file-url "URL provided by user" --file-type 0 --pretty

• --file-type 0: PDF
• --file-type 1: image
• If omitted, the type is auto-detected from the file extension. For local files, a recognized extension (.pdf, .png, .jpg, .jpeg, .bmp, .tiff, .tif, .webp) is required; otherwise pass --file-type explicitly. For URLs with unrecognized extensions, the service attempts inference.

> Performance note: Parsing time scales with document complexity. Single-page images typically complete in 1-5 seconds; large PDFs (50+ pages) may take several minutes. Allow adequate time before assuming a timeout.

Default behavior: output JSON to stdout:
- By default, the script prints JSON to stdout — no files are created on disk
- Use --output FILE to save the result to a specific file path
- This avoids leaving sensitive document data in temp directories

3. Parse JSON response:
   - Check the ok field: true means success, false means error
   - The output contains complete document data: text, tables, formulas (LaTeX), figures, seals, headers/footers, and reading order
   - Use the appropriate field based on what the user needs:

   • text — full document text across all pages
   • result.result.layoutParsingResults[n].markdown.text — page-level markdown
   • result.result.layoutParsingResults[n].prunedResult — structured layout data with positions and confidence
   • Handle errors: If ok is false, display error.message

4. Present results to user:
   - Display content based on what the user requested (see "Complete Output Display" below)
   - If the content is empty, the document may contain no extractable text
   - In save mode, always tell the user the saved file path and that full raw JSON is available there

What to Do After Parsing

Common next steps once you have the structured output:

• Save as Markdown: Write the text field to a .md file — tables, headings, and formulas are preserved
• Extract specific tables: Navigate result.result.layoutParsingResults[n].prunedResult to access individual layout elements with position and confidence data
• Feed to RAG / search pipeline: The text field is structured markdown, ready for chunking and indexing
• Poor results: See "Tips for Better Results" below before retrying

Complete Output Display

Display the COMPLETE extracted content based on what the user asked for. The parsed output is only useful if the user receives all of it — truncation silently drops data.

• If user asks for "all text", show the entire text field
• If user asks for "tables", show ALL tables in the document
• If user asks for "main content", filter out headers/footers but show ALL body text
• Do not truncate with "..." unless content is excessively long (>10,000 chars)
• Do not say "Here's a preview" when user expects complete output

Example - Correct:

User: "Extract all the text from this document"
Agent: I've parsed the complete document. Here's all the extracted text:

[Display entire text field or concatenated regions in reading order]

Document Statistics:
- Total regions: 25
- Text blocks: 15
- Tables: 3
- Formulas: 2
Quality: Excellent (confidence: 0.92)

Example - Incorrect:

User: "Extract all the text"
Agent: "I found a document with multiple sections. Here's the beginning:
'Introduction...' (content truncated for brevity)"

Understanding the Output

The script returns an envelope with ok, text, result, and error. Use text for the full document content; navigate result.result.layoutParsingResults[n] for per-page structured data.

For the complete schema and field-level details, see references/output_schema.md.

Usage Examples

Example 1: Extract Full Document Text (stdout)

uv run scripts/layout_caller.py \
  --file-url "https://example.com/paper.pdf" \
  --pretty

Then use:

• Top-level text for quick full-text output
• result.result.layoutParsingResults[n].markdown when page-level output is needed

Example 2: Extract Structured Page Data

uv run scripts/layout_caller.py \
  --file-path "./financial_report.pdf" \
  --pretty

Then use:

• result.result.layoutParsingResults[n].prunedResult for structured parsing data (layout/content/confidence)

Example 3: Save result to a file

uv run scripts/layout_caller.py \
  --file-url "URL" \
  --output "./result.json" \
  --pretty

By default the script prints JSON to stdout. Use --output to save to a file.

Configuration

Set PADDLEOCR_DOC_PARSING_API_URL to the AMD Radeon Cloud endpoint URL:

export PADDLEOCR_DOC_PARSING_API_URL="http://134.199.132.159/layout-parsing"

No API key, no token, no sign-up needed. The AMD Radeon Cloud free PaddleOCR-VL 1.5 service requires no authentication.

Optional overrides:
- PADDLEOCR_DOC_PARSING_TIMEOUT — Request timeout in seconds (default: 600)

Handling Large Files

For PDFs, the maximum is 100 pages per request.

Optimize Large Images Before Parsing

For large image files, compress before uploading — this reduces upload time and can improve processing stability:

uv run scripts/optimize_file.py input.png output.jpg --quality 85
uv run scripts/layout_caller.py --file-path "output.jpg" --pretty

--quality controls JPEG/WebP lossy compression (1-100, default 85); it has no effect on PNG output. Use --target-size (in MB, default 20) to set the max file size — the script iteratively downscales until the target is met.

Use URL for Large Local Files (Recommended)

For very large local files, prefer --file-url over --file-path to avoid base64 encoding overhead:

uv run scripts/layout_caller.py --file-url "https://your-server.com/large_file.pdf"

Process Specific Pages (PDF Only)

If you only need certain pages from a large PDF, extract them first:

# Extract pages 1-5
uv run scripts/split_pdf.py large.pdf pages_1_5.pdf --pages "1-5"

# Mixed ranges are supported
uv run scripts/split_pdf.py large.pdf selected_pages.pdf --pages "1-5,8,10-12"

# Then process the smaller file
uv run scripts/layout_caller.py --file-path "pages_1_5.pdf"

Error Handling

All errors return JSON with ok: false. Show the error message and stop — do not fall back to your own vision capabilities. Identify the issue from error.code and error.message:

API service error (5xx) — error.message contains "API service error"

• Temporary server issue; retry after a moment

Rate limit exceeded (429) — error.message contains "API rate limit exceeded"

• Wait and retry

Unsupported format — error.message contains "Unsupported file format"

• File format not supported, convert to PDF/PNG/JPG

No content detected:

• text field is empty
• Document may be blank, image-only, or contain no extractable text

Tips for Better Results

If parsing quality is poor:

• Large or high-resolution images: Compress with optimize_file.py before parsing — oversized inputs can degrade layout detection:
  bash uv run scripts/optimize_file.py input.png optimized.jpg --quality 85
• Check confidence: result.result.layoutParsingResults[n].prunedResult includes confidence scores per layout element — low values indicate regions worth reviewing

Testing the Skill

To verify the skill is working properly:

uv run scripts/smoke_test.py
uv run scripts/smoke_test.py --skip-api-test
uv run scripts/smoke_test.py --test-url "https://..."

The first form tests configuration and API connectivity. --skip-api-test checks configuration only. --test-url overrides the default sample document URL.
