This is very simple Telegram bot checking new ads on Ebay-Kleinanzeigen.de.
It accepts just a link to a page with the search results (i.e. https://www.ebay-kleinanzeigen.de/s-pc-zubehoer-software/grafikkarten/81825/anzeige:angebote/preis:100:500/c225l16390r150+pc_zubehoer_software.art_s:grafikkarten) and then starts monitoring this page (by default every 15 minutes).
When some new ad appears, you'll be notified.
No rocket science here, I made it just for myself and the simplest approach worked well. Bot remembers the topmost
item in the list for the current chat_id and during subsequent checks prints all the ads until the last remembered item
is met. Obviously, this will cause a full update if the last item disappeared, but during ~2 weeks of usage I haven't really noticed
such a case.
Python 3.6+ and Docker (preferrably)
The bot can be run in webhook and polling modes. For webhook, bot has to be accessible over HTTPS from external Internet.
Commands for running:
git pull
docker-compose build
docker-compose up -d
NOTE: I do not plan to host this bot publicly available (in contrast with Munich Termin Notifier bot) because it seems to have much more personalized queries and there is no point in analyzing the data in a single place.
