VAT Validation
Abstract's VAT Validation & Rates API checks whether an EU VAT number is currently registered, returns the associated company name and address, and calculates VAT-inclusive prices using its live per-country rate table. Its free tier is a one-time 100-request lifetime trial rather than a recurring monthly allowance, so most integrations move to the $99/month Standard plan (60,000 requests/month) or higher.
