EbayKleinanzeigenCrawler

.NET 5.0 based crawler that parses Ebay Kleinanzeigen classified ads and notifies via a Telegram Bot.

Features:

• Notifies you reliably about new articles within 5 minutes!
• Searches for keywords in title and description!
• Specify which search keywords to include and which to exclude!
• Specify a subscription by simply copying the URL from your browser
• Uses Telegram as interface for notifications and control
• Supports multiple Subscribers and Subscriptions
• You can easily add different interfaces (Console, E-Mail, SMS, ...)
• Persists data in JSON files

Before use:

• Create your own Telegram Bot
• Set the environment variable TELEGRAM_BOT_TOKEN to your token.

How to use:

• Send /help to the Telegram bot for instructions
• Currently only works with Desktop-Browser links, not mobile browser links. (https://www.ebay-kleinanzeigen.de/....)
• Ebay Kleinanzeigen obfuscates its HTML with JavaScript, when more than 40 queries are made within the last 5 minutes. This software considers this limit.
• This software is work in progress. There are many TODOs in the code. Feel free to contribute :-)
