VIES Smoother is answering right now. Last checked 12 min ago. It exposes 2 tools.
SLA'd EU VAT validation on VIES. Honest 3-state result, never guesses. 100 free lookups.
Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.
Endpoint below is the one we actually reach during checks — not the one copied from a README. Last verified 12 min ago.
