## About

## What it does
VAT Company Lookup lets you verify a VAT number and retrieve the company details associated with it. Send a single `vat` value in the request body, and get back the validation result plus the matching company record when it is available.

Use it when you need to confirm customer or supplier tax IDs during onboarding, invoicing, or checkout. The response includes `valid` along with the company `name`, `address`, `vat_number`, and `country_code` inside `data`, so you can decide whether to trust the identifier and display the registered business details.

It is a good fit for compliance checks, B2B account creation, and reducing manual review of VAT entries. If the number is invalid or cannot be resolved, the API still gives you a structured response you can handle programmatically.

Keep the input to the full VAT number, including the two-letter country prefix.
