CamelCamelCamel Alerts

Automatically monitor your CamelCamelCamel RSS feed for Amazon price drops and get notified on Telegram.

Quick Start

Get your RSS feed URL from CamelCamelCamel:
- Go to https://camelcamelcamel.com/ and set up price alerts
- Get your personal RSS feed URL (format: https://camelcamelcamel.com/alerts/YOUR_UNIQUE_ID.xml)
Create a cron job with YOUR feed URL (not someone else's!):

cron add \
  --job '{
    "name": "camelcamelcamel-monitor",
    "schedule": "0 */12 * * *",
    "task": "Monitor CamelCamelCamel price alerts",
    "command": "python3 /path/to/scripts/fetch_rss.py https://camelcamelcamel.com/alerts/YOUR_UNIQUE_ID.xml"
  }'

Important: Replace YOUR_UNIQUE_ID with your own feed ID from step 1. Each person needs their own feed URL!

Clawdbot will:
- Fetch your feed every 4 hours
- Detect new price alerts
- Send you Telegram notifications

How It Works

The skill uses two components:

`scripts/fetch_rss.py`

Fetches your CamelCamelCamel RSS feed
Parses price alert items
Compares against local cache to find new alerts
Outputs JSON with new items detected
Caches item hashes to avoid duplicate notifications

Cron Integration

Runs on a schedule you define
Triggers fetch_rss.py
Can be configured to run hourly, every 4 hours, daily, etc.

Setup & Configuration

Troubleshooting

Alert Cache

The script maintains a cache at /tmp/camelcamelcamel/cache.json to track which alerts have been notified. This prevents duplicate notifications.

Clear the cache to re-test notifications:

rm /tmp/camelcamelcamel/cache.json

Notification Format

When a new price drop is detected, you'll receive a Telegram message like:

🛒 *Price Alert*

*PRODUCT NAME - $XX.XX (Down from $YY.YY)*

Current price: $XX.XX
Historical low: $ZZ.ZZ
Last checked: [timestamp]

View on Amazon: [link]

Customization

Check Frequency

Adjust the cron schedule (6th parameter in the schedule field):

0 * * * * → every hour
0 */4 * * * → every 4 hours (default)
0 */6 * * * → every 6 hours
0 0 * * * → daily

Message Format

Edit scripts/notify.sh to customize the Telegram message layout and emoji.

Troubleshooting
