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. The following free API key will work still until the end of September: 573e58c665fcc08cc6e5a660beaad0cb

For anytime thereafter, you can purchase your personal EST API Key here. Your API key costs 9 USD and will be valid for one month from the time of purchase. You support is essential for us to be able to further maintain and develop this website!
