Where can I find my VAT Invoice?

Invoices are generated automatically. Log in to your Dashboard, go to Settings > Billing History. You can download PDF invoices there instantly.

Why is my API Key not working?

Ensure you are using the correct endpoint: https://api.indexchecker.link/v1/. Check if you have active credits. If credits are 0, the API returns a 402 Payment Required error.
