All our applications can be used free of charge in the browser. If you want to run analyses
programmatically instead, use the EST APIs together with our client libraries for R, Python,
Stata, MATLAB, SAS and PHP: github.com/EventStudyTools.
The underlying protocol is documented on the API documentation page.
Free research keys are available to academic users. To qualify, request your key with your
university email address: either an address ending in .edu or an address belonging to a
recognized European university or business school. Student and departmental addresses
(for example [email protected]) work as well. General (non-academic) key access
is currently paused.
How the keys work
- Keys are valid for one month; the exact expiry date is included in the delivery email.
- One key per address: a new key can be requested once the current one has expired.
- We are soft-starting the program with a batch of 50 keys: at most
50 keys are active at any time for now, and we will raise the batch size as the
program settles in. When the batch is fully allocated, new requests join a waitlist and receive
their key automatically, in order, as current keys expire.
- Fair use: the free tier covers up to 250 analyses per day and
1,500 analyses per key month. We send a heads-up as you approach the monthly
allowance; exceeding it excludes the address from future free keys, so the shared research
infrastructure stays responsive for everyone. If your project needs more capacity,
talk to us.
