# Felo Web Fetch Skill

When to Use

Trigger this skill when the user wants to:

• Fetch 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):

• fetch webpage, scrape URL, fetch page content, web fetch, url to markdown
• Explicit: /felo-web-fetch, "use felo web fetch"
• 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

• Visit felo.ai
• Open Settings -> API Keys
• Create and copy your API key

2. Configure environment variable

Linux/macOS: ``bash export FELO_API_KEY="your-api-key-here" ` Windows PowerShell: `powershell $env:FELO_API_KEY="your-api-key-here" `

How to Execute

Option A: Use the bundled script or packaged CLI

Script (from repo): `bash node felo-web-fetch/scripts/run_web_fetch.mjs --url "https://example.com/article" [options] ` Packaged CLI (after npm install -g felo-ai): same options, with short forms allowed: `bash felo web-fetch -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 fetch | | --format | markdown | Output format: html, text, markdown | | --target-selector | - | CSS selector: fetch only this element (e.g. article.main, #content) | | --wait-for-selector | - | Wait for this selector before fetching (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: "Fetch 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" / "Fetch 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 | |-------------|---------| | "Fetch this page as plain text" | --url "..." --format text | | "Get only the main content area" | --url "..." --target-selector "main" or article | | "Fetch 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: `bash # Basic: fetch as Markdown node felo-web-fetch/scripts/run_web_fetch.mjs --url "https://example.com" # Article-style with readability node felo-web-fetch/scripts/run_web_fetch.mjs --url "https://example.com/article" --readability --format markdown # Raw HTML node felo-web-fetch/scripts/run_web_fetch.mjs --url "https://example.com" --format html --json # Only the element matching a CSS selector (e.g. main article) node felo-web-fetch/scripts/run_web_fetch.mjs --url "https://example.com" --target-selector "article.main" --format markdown # Specific output format + target selector node felo-web-fetch/scripts/run_web_fetch.mjs --url "https://example.com" --target-selector "#content" --format text `

Option B: Call API with curl

`bash 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}' `

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).
