Limit on API calls

יוסף 1 month ago updated by Michael J. Radwin 1 month ago 1

Hello everyone, I have a question Is there a limit to how many API calls can be made in one minute to the system?

I have an automation process that converts a foreign date to me and it is important for me to know that everything will work and not break due to the load of API calls

Thanks for using the Hebcal APIs!


You may receive a 429 “Too Many Requests” error if your client makes more than 90 requests in a 10-second window.

Many of our APIs support batch queries, and those should be used when possible to avoid hitting our rate limits. We also generate proper HTTP Cache-Control and/or Expires headers so your client can optionally use a caching proxy to avoid actually incurring load on our APIs if you end up fetching the same information multiple times. By design Hebcal APIs are stateless and idempotent.

If for some reason you are running up against the rate limits can you please share your use case with us? If you have a use case we haven't considered we would love to hear about it!
