Usage

From OpenClaw

text

user: Secure this API key: sk-abc123xyz

claw: I'll create a secure, self-destructing note for that.
      [runs: echo "sk-abc123xyz" | fadnote]

      🔗 https://fadnote.com/n/abc123# decryption-key-here

      Share it with the recipient via any channel and this link will self-destruct after first view.

CLI Usage

bash

  Usage: fadnote [options] [text]
         echo "text" | fadnote [options]

  Create secure self-destructing notes that can only be viewed once.

  Options:
    -h, --help          Show this help message and exit
        --ttl <secs>    Time until note expires (default: 86400 = 24h)
        --json          Output JSON with noteId, expiresIn, and decryptionUrl

  Environment:
    FADNOTE_URL         API endpoint (default: https://fadnote.com)

  Examples:
    # Standard
    fadnote "My secret message" # direct input
    echo "My secret" | fadnote # from stdin

    # With options
    fadnote --ttl 3600 "Expires in 1 hour" # Custom TTL
    fadnote --json --ttl 7200 "JSON output" # JSON output:
      # {noteId: string, expiresIn: number, decryptionUrl: string}

    # File and clipboard input
    cat file.txt | fadnote --ttl 86400 # from stdin with options
    pbpaste | fadnote  # macOS clipboard
    xclip -o -selection clipboard | fadnote # from clipboard (Linux with xclip)
    xsel -b | fadnote # from clipboard (Linux with xsel)

Single Output: Single line with the shareable URL.

JSON Output:

json

{
  noteId: string,
  expiresIn: number,
  decryptionUrl: string
}

Triggers

I (OpenClaw) will automatically use the FadNote skill when you say any of:

• "Secure this [content]"
• "FadNote this [content]"
• "Create a secure link for [content]"
• "Share this securely: [content]"
• "One-time note: [content]"
• "Encrypt and share [content]"

With email delivery (if email skill is present):

• "Secure this and email to [recipient]: [content]"
• "FadNote this to [email]"
• "Send secure note to [email]"

Examples:

text

- Secure this API key: sk-live-12345

- FadNote this password for the server

- Create a secure link for these credentials

- Share this securely: my private SSH key

- One-time note: the meeting location

---

Security

• Client-side encryption — AES-256-GCM with PBKDF2 (600k iterations)
• Zero knowledge — Server receives only encrypted blobs
• One-time read — Note deleted immediately after first fetch
• Auto-expire — Default 24 hour TTL
• Open Source — Server code is publicly auditable at https://github.com/easyFloyd/fadnote

The decryption key is embedded in the URL fragment (#key) and never sent to the server.

FADNOTE_URL not set	Environment variable missing	export FADNOTE_URL=https://fadnote.com
Empty note	No input provided	Pipe text into fadnote: echo "secret" | fadnote
404 Not Found	Server endpoint wrong	Check FADNOTE_URL points to a running FadNote instance
Connection refused	Server unreachable	Verify server is up or use the live service
Crypto not available	Node.js < 18	Upgrade to Node.js 18+
