API Key

If you want to use our API for performing event studies in a programmatic manner, you need an API key - this applies both to the R package and any other implementation you develop on your own. You can purchase your personal EST API Key here. The API key costs 9 USD and will be valid for one month from the time of purchase. Your support is essential for us to be able to further maintain and develop this website!

Please note: up till September 2020, we provided a free API key (573e58c665fcc08cc6e5a660beaad0cb), which now ceased to work. If you were using this key, you now need to obtain your personal EST API Key.
