EU VAT number validation against the official VIES registry, and global LEI validation with corporate ownership chains against GLEIF. Choose a plan, pay with PayPal, and your API key arrives by email. No marketplace in the middle, no reseller markup.
Two HTTP APIs, sold as a subscription. Every plan includes both products. Both are operated by the same developer who wrote them.
Validate EU and UK VAT numbers against the European Commission VIES registry. One call returns the registration status, the registered company name and the registered address.
Validate Legal Entity Identifiers against a locally indexed copy of the complete GLEIF registry, and resolve the corporate ownership chain around an entity.
Prepaid monthly plans. Every plan is a hard quota, so you are never billed for overage. There is no automatic renewal — you decide each month whether to continue.

This is a small, developer-run shop. Orders are fulfilled by hand, which is why the process below is explicit about what happens after you pay.
Pick the request volume you need. Every plan covers both APIs.
Clicking the plan button opens the PayPal checkout. The payment is sent to our PayPal
account (paypal.me/godchin520). You may pay with a PayPal balance, a
linked bank account, or a card.
Email your PayPal receipt, or the PayPal transaction ID, to godchin520@163.com. That is how we match the payment to your order.
We reply with your API key, the base URL and the endpoint reference. Keys are issued within one business day, usually much sooner.
This store is operated by the developer of the APIs sold on it. The details below are the same ones registered with PayPal for this merchant account.

| VAT data source | European Commission VIES registry, queried live and cached. Results are provided as-is and do not constitute tax or legal advice. |
|---|---|
