## About

## What it does
VAT Number Validator checks whether a VAT number is valid. Send a `vat` string that includes the 2-letter country code prefix, and it returns a boolean result in `data`.

Use it when you need to verify tax IDs during sign-up, invoicing, vendor onboarding, or checkout. The response is intentionally simple, so it fits cleanly into validation flows where you only need a pass or fail signal.

VAT Number Validator is a good fit for systems that accept business customers across multiple countries and need a fast way to reject malformed or invalid VAT entries before they reach your records.

Because the input and output are minimal, it’s easy to add this check in front of a database write, a payment step, or a compliance workflow without extra parsing.

## Usage

Authenticate with an ApyHub API key in the `apy-token` header.
