Hebcal Developer API minor updates

Posted on by

We’re pleased to share a couple of brief and minor updates to our collection of Developer APIs.

  1. We now recommend using HTTPS for all of our APIs. We’ve updated our documentation to reflect this. Most of our JSON APIs still support HTTP. Some of our APIs now return a 301 redirect from the HTTP version to the HTTPS version.

  2. We implemented some simplistic rate-limiting to throttle clients who are sending too many API queries. You may receive a 429 “Too Many Requests” error if your client makes more than 90 requests in a 10-second window. Remember, this is a free service; please be polite and send batch API requests slowly over a longer period of time.
