I am pleased to announce the new release of the VATValidation. With this new release, VATValidation supports BZSt, VIES, HMRC and new Swiss UID). The CLI got some improvements to be able to switch between VIES and BZSt. UID is automatically choosen, as soon as an swiss UID is detected (similar to HMRC).

Great job! 👏 Tax validation APIs often become targets for enumeration or automation abuse. Curious how you are approaching rate limiting and response consistency across VIES, BZSt and HMRC?

@nautillo since it is a local client, which sends the requests from the local network of the users and not centrally, the rate limit is (luckily) not an issue. The interfaces itself can be choosen manually (e.g. VIES and BZSt), but for british or swiss entries, the VATValidation choose automatically the right interface. This also minimize the risk of "flooding" the interfaces itself.
