# Introduction

`vatcheckapi` is the official package for accessing VAT ID data from [vatcheckapi.com](https://vatcheckapi.com). The API requires a registered API key. The free plan provides 100 free monthly requests. You can register an API key [here](https://app.vatcheckapi.com/register). [Premium plans](https://vatcheckapi.com/pricing/) provide access to more requests and more data endpoints. The full API documentation can be found [here](https://vatcheckapi.com/docs/)

## Setting up authentication

After registering your API key, set your API key locally by calling the helper function `vatcheckapi_api_key()` or by manually calling `Sys.setenv(VATCHECKAPI_API_KEY = <key>)`.

## Making your first API request

Call `get_vat_info("LU26375245")` to retrieve all information about the specified VAT ID.

## Available Functions

* `get_api_status()` - can be used to check whether the API is available. Requests do not count towards your monthly request volume. Information about your API key are provided. Available in `free & paid` plans.
* `get_vat_info()` - provides you with information about any VAT ID. Available in `free & paid` plans.

Please read our [API documentation](https://vatcheckapi.com/docs/) for all information.
