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}'

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).
