# Limits

## Query/Mutation

To protect our endpoint from being overwhelmed, we have rate limits in place. For query/mutation, there is a 5000 limit per 5 minute interval.

Every response header will have 3 rate-limit headers:

* `Ratelimit-Limit` — The maximum number of api calls in this interval (currently always 5000).
* `Ratelimit-Remaining` — The number of api calls you have left in this interval.
* `Ratelimit-Reset` — A Unix epoch timestamp of when the current interval ends.

Any request beyond the limit would receive an HTTP response code of 429 Too Many Requests.

## Subscription

* Client could listen up to 50 endpoints per web socket connection. Attempting to listen to more would return an error.
* Each endpoint has a buffer size of 30. If client are too slow to read, the particular endpoint would be closed.
* Each IP could establish up to 100 web socket connections.
