## About

## What it does
VAT Batch Validator checks up to 10 VAT numbers in a single request and returns a per-item result for each one.

Send a `vat_numbers` array of strings in the request body. The response returns a `data` array, where each item includes the original `vat` and a boolean `valid` flag. If a lookup fails for a specific item, that entry can also include an `error` string so you can separate invalid numbers from verification issues.

Use VAT Batch Validator when you need to screen customer, supplier, or invoice records before storing them, billing them, or routing them into a tax workflow. Batch validation is useful for import jobs, CRM cleanup, and checkout or onboarding flows where you want to catch bad VAT numbers early without making one request per record.

The service is limited to small batches, so it fits lightweight validation pipelines and UI-driven checks where fast, structured feedback matters.
