Felo Web Extract Skill

When to Use

Trigger this skill when the user wants to:

• Extract or scrape content from a webpage URL
• Get article/main text from a link
• Convert a webpage to Markdown or plain text
• Capture readable content from a URL for summarization or processing

Trigger keywords (examples):

• extract webpage, scrape URL, fetch page content, web extract, url to markdown
• Explicit: /felo-web-extract, "use felo web extract"
• Same intent in other languages (e.g. 网页抓取, 提取网页内容) also triggers this skill

Do NOT use for:

• Real-time search or Q&A (use felo-search)
• Generating slides (use felo-slides)
• Local file content (read files directly)

Setup

1. Get API key

1. Visit felo.ai
2. Open Settings -> API Keys
3. Create and copy your API key

2. Configure environment variable

Linux/macOS:

export FELO_API_KEY="your-api-key-here"

Windows PowerShell:

$env:FELO_API_KEY="your-api-key-here"

How to Execute

Option A: Use the bundled script or packaged CLI

Script (from repo):

node felo-web-extract/scripts/run_web_extract.mjs --url "https://example.com/article" [options]

Packaged CLI (after npm install -g felo-ai): same options, with short forms allowed:

felo web-extract -u "https://example.com" [options]
# Short forms: -u (url), -f (format), -t (timeout, seconds), -j (json)

Options:

| Option | Default | Description |

|--------|---------|-------------|

| --url | (required) | Webpage URL to extract |

| --format | markdown | Output format: html, text, markdown |

| --target-selector | - | CSS selector: extract only this element (e.g. article.main, #content) |

| --wait-for-selector | - | Wait for this selector before extracting (e.g. dynamic content) |

| --readability | false | Enable readability processing (main content only) |

| --crawl-mode | fast | fast or fine |

| --timeout | 60000 (script) / 60 (CLI) | Request timeout: script uses milliseconds, CLI uses seconds (e.g. -t 90) |

| --json / -j | false | Print full API response as JSON |

How to write instructions (target_selector + output_format)

When the user wants a specific part of the page or a specific output format, phrase the command like this:

• Output format: "Extract as text" / "Get markdown" / "Return html" → use --format text, --format markdown, or --format html.
• Target one element: "Only the main article" / "Just the content inside #main" / "Extract only article.main-content" → use --target-selector "article.main" or the selector they give (e.g. #main, .main-content, article .post).

Examples of user intents and equivalent commands:

| User intent | Command |

|-------------|---------|

| "Extract this page as plain text" | --url "..." --format text |

| "Get only the main content area" | --url "..." --target-selector "main" or article |

| "Extract the div with id=content as markdown" | --url "..." --target-selector "#content" --format markdown |

| "Just the article body, as HTML" | --url "..." --target-selector "article .body" --format html |

Examples:

# Basic: extract as Markdown
node felo-web-extract/scripts/run_web_extract.mjs --url "https://example.com"

# Article-style with readability
node felo-web-extract/scripts/run_web_extract.mjs --url "https://example.com/article" --readability --format markdown

# Raw HTML
node felo-web-extract/scripts/run_web_extract.mjs --url "https://example.com" --format html --json

# Only the element matching a CSS selector (e.g. main article)
node felo-web-extract/scripts/run_web_extract.mjs --url "https://example.com" --target-selector "article.main" --format markdown

# Specific output format + target selector
node felo-web-extract/scripts/run_web_extract.mjs --url "https://example.com" --target-selector "#content" --format text

Option B: Call API with curl

curl -X POST "https://openapi.felo.ai/v2/web/extract" \
  -H "Authorization: Bearer $FELO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"url": "https://example.com", "output_format": "markdown", "with_readability": true}'

Response

Success (200):

{
  "code": 0,
  "message": "success",
  "data": {
    "content": { ... }
  }
}

Extracted content is in data.content; structure depends on output_format.

Error codes

| HTTP | Code | Description |

|------|------|-------------|

| 400 | - | Parameter validation failed |

| 401 | INVALID_API_KEY | API key invalid or revoked |

| 500/502 | WEB_EXTRACT_FAILED | Extract failed (server or page error) |

Output Format

On success (script without --json):

• Print the extracted content only (for direct use or piping).

With --json:

• Print full API response including code, message, data.

Error response to user:

## Web Extract Failed

- Error: <code or message>
- URL: <requested url>
- Suggestion: <e.g. check URL, retry, or use --timeout>

Important Notes

• Always check FELO_API_KEY before calling; if missing, return setup instructions.
• For long articles or slow sites, consider --timeout or timeout in request body.
• Use output_format: "markdown" and with_readability: true for clean article text.
• API may cache results; use with_cache: false in body only when fresh content is required (script does not expose this by default).
