Some API endpoints are rate limited, the current endpoints with this enabled are:
If you hit rate limits you will be served with a JSON error message along with 429 status code. Requests made that give a 429 response do not contribute to the rate limiting count.
The current rate limits are a rolling 180 second period, with 50x requests within a period, however this may change in the future. It is best to implement a solution that can handle and retry requests when rate limits are hit.
