# Rate Limits & Throttling

The Sway Charts REST API supports per-client configurable maximum API access rate. This rate limits how frequently the API can be accessed. There are three types of rate limits:

* For login requests based on IP of the request. Default value 1 per second
* For 'get data' requests based on client session, default value 2 per second.
* For trading requests(placing / modifying / canceling orders) based on client session, default value 1 per second. Default value permits accessing each resource available to client no faster than once a second.

If access rate is exceeded, the server responds with the `429 Too Many Requests`.
