I recently created a new company and the French tax authority assigned me a tax number. Unfortunately it's not in some database yet, which means if I try to use it on a European provider like Hetzner, it'll reject my VAT number.
So I made (with a little help from GPT-4o/Claude 3.5 Sonnet) a Telegram bot to send me a message when the VAT number finally becomes valid.
I check that using the VIES API provided by the European Commission.
Unfortunately you'll need to deploy the bot yourself if you want to run it, I'm not running it as a general-purpose but right now.
It's fun though!
