Screenshot Telegram Direct

Capture website screenshots and send to Telegram via direct API. Works around OpenClaw's broken image delivery (issue

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

Quick Start

bash

# 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:

bash

# 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

bash

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:

bash

# 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:

bash

#!/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: Modify screenshot-send.sh to auto-source

The script already checks for env vars. To auto-source .env if it exists, add at the top:

bash

# Auto-source .env if it exists in script directory
SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
if [ -f "$SCRIPT_DIR/.env" ]; then
    source "$SCRIPT_DIR/.env"
fi

3. Make Script Executable

bash

chmod +x screenshot-send.sh

Usage

Basic screenshot

bash

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

Custom caption

bash

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

Multiple URLs

bash

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:

bash

# 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"

Option	Description
full_page	Capture entire scrollable page
width/height	Viewport size
dark_mode	Emulate dark color scheme
wait_ms	Wait for JS rendering
format	png or jpeg

Send as Document (No Compression)

Replace sendPhoto with sendDocument in the script:

bash

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)

bash

# 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

File Structure

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

Issue	Fix
Missing environment variables	Check .env exists and is sourced
Failed to capture screenshot	Check SNAP_API_KEY is valid
chat not found	Verify TELEGRAM_CHAT_ID
bot was blocked	Send /start to bot in Telegram

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.
