GLM-OCR Text Extraction Skill

Extract text from images and PDFs using the GLM-OCR layout parsing API.

When to Use

• Extract text from images (PNG, JPG, PDF)
• Convert screenshots to text
• Process scanned documents
• OCR photos containing text (including handwritten text)
• Recognize tables and formulas in documents
• User mentions "OCR", "文字识别", "文档解析"

Key Features

• Table recognition: Detects and converts tables to Markdown format
• Formula extraction: LaTeX format output
• Handwriting support: Strong recognition for handwritten text
• Local file & URL: Supports both local files and remote URLs

Prerequisites

• ZHIPU_API_KEY configured (see Setup below)

Security Notes

• No runtime package installation is performed by the scripts.
• OCR requests use the fixed official GLM endpoint and do not accept custom API URLs.
• Only ZHIPU_API_KEY (and optional timeout) is read from environment variables.

⛔ MANDATORY RESTRICTIONS - DO NOT VIOLATE ⛔

1. ONLY use GLM-OCR API - Execute the script python scripts/glm_ocr_cli.py
2. NEVER parse documents directly - Do NOT try to extract text yourself
3. NEVER offer alternatives - Do NOT suggest "I can try to analyze it" or similar
4. IF API fails - Display the error message and STOP immediately
5. NO fallback methods - Do NOT attempt text extraction any other way

Setup

1. Get your API key: https://www.bigmodel.cn/usercenter/proj-mgmt/apikeys
2. Configure: python scripts/config_setup.py setup --api-key YOUR_KEY

How to Use

Extract from URL

python scripts/glm_ocr_cli.py --file-url "URL provided by user"

Extract from Local File

python scripts/glm_ocr_cli.py --file /path/to/image.jpg

Save result to file (recommended)

python scripts/glm_ocr_cli.py --file-url "URL" --output result.json

CLI Reference

python {baseDir}/scripts/glm_ocr_cli.py (--file-url URL | --file PATH) [--output FILE] [--pretty]

Response Format

{
  "ok": true,
  "text": "# Extracted text in Markdown...",
  "layout_details": [[...]],
  "result": { "raw_api_response": "..." },
  "error": null,
  "source": "/path/to/file.jpg",
  "source_type": "file"
}

Key fields:

• ok — whether extraction succeeded
• text — extracted text in Markdown (use this for display)
• layout_details — layout analysis details
• result — raw API response
• error — error details on failure

Error Handling

API key not configured:

Error: ZHIPU_API_KEY not configured. Get your API key at: https://www.bigmodel.cn/usercenter/proj-mgmt/apikeys

→ Show exact error to user, guide them to configure

Authentication failed (401/403): API key invalid/expired → reconfigure

Rate limit (429): Quota exhausted → inform user to wait

File not found: Local file missing → check path
