Screenshot → Telegram (Direct)

Capture website screenshots and send them to Telegram, bypassing OpenClaw's broken image delivery pipeline.

Quick Start

# 1. Setup environment
cp .env.example .env
# Edit .env with your tokens

# 2. Run the helper script
./screenshot-send.sh https://github.com

Setup

1. Get API Credentials

Telegram Bot Token:

• Message @BotFather
• Send /mybots → Select bot → Copy API token

Telegram Chat ID:

• Personal: Message @userinfobot
• Group: Add @RawDataBot to group

Snap API Key:

# Register for free API key
curl -s -X POST https://snap.llm.kaveenk.com/api/register \
  -H "Content-Type: application/json" \
  -d '{"name":"my-agent"}'
# Save the "key" from response

2. Configure

cp .env.example .env
# Edit .env:
# TELEGRAM_BOT_TOKEN=your_token
# TELEGRAM_CHAT_ID=your_chat_id
# SNAP_API_KEY=your_snap_key

# Source it (temporary)
source .env

3. Auto-Load .env (Recommended for OpenClaw)

Option A: Add to shell profile (always available)

Add to ~/.bashrc or ~/.zshrc:

# Auto-load screenshot-telegram-direct env vars
SKILL_DIR="$HOME/.openclaw/workspace/skills/screenshot-telegram-direct"
if [ -f "$SKILL_DIR/.env" ]; then
    export $(grep -v '^#' "$SKILL_DIR/.env" | xargs)
fi

Then reload: source ~/.bashrc

Option B: Source before each OpenClaw session

In your OpenClaw workspace, create load-env.sh:

#!/bin/bash
source "$HOME/.openclaw/workspace/skills/screenshot-telegram-direct/.env"
echo "✅ Environment loaded from screenshot-telegram-direct/.env"

Run before using: source load-env.sh

Option C: Script auto-sources .env

The screenshot-send.sh script automatically sources .env from its directory if present.

3. Make Script Executable

chmod +x screenshot-send.sh

Usage

Basic screenshot

./screenshot-send.sh https://example.com

Custom caption

./screenshot-send.sh https://github.com "Latest PR status"

Multiple URLs

for url in "https://github.com" "https://news.ycombinator.com"; do
  ./screenshot-send.sh "$url"
  sleep 2
done

Configuration Options

Snap API Options

Edit screenshot-send.sh to customize:

# Full page screenshot
curl -s -X POST "https://snap.llm.kaveenk.com/api/screenshot" \
  -H "Authorization: Bearer $SNAP_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "'$URL'",
    "full_page": true,
    "width": 1920,
    "height": 1080,
    "dark_mode": true,
    "wait_ms": 2000
  }' \
  -o "$OUTPUT_FILE"

Send as Document (No Compression)

Replace sendPhoto with sendDocument in the script:

curl -s -X POST \
  -F "chat_id=$CHAT_ID" \
  -F "document=@$OUTPUT_FILE" \
  -F "caption=$CAPTION" \
  "https://api.telegram.org/bot$TOKEN/sendDocument"

Automation (Cron)

# Daily dashboard screenshot
0 9 * * * cd /home/pi/.openclaw/workspace/skills/screenshot-telegram-direct && ./screenshot-send.sh https://status.example.com

# Hourly monitoring
0 * * * * cd /home/pi/.openclaw/workspace/skills/screenshot-telegram-direct && ./screenshot-send.sh https://uptime.example.com

Security

• ✅ .env is gitignored — never commit secrets
• ✅ .env.example shows required variables without values
• ✅ Script fails if env vars are missing
• ✅ No hardcoded credentials

Troubleshooting

Why Not Use OpenClaw Native?

See OpenClaw issue #63137: Images sent via read tool render locally but never reach mobile clients — silent failure with no error logs.

This skill bypasses OpenClaw's Telegram channel entirely using direct HTTP API calls.
