# Rate limits

The SWYCO API has various safeguards to maintain stability during high-traffic periods. Users sending numerous requests in a short period may receive error responses with status code 429. The API includes:

* A rate restriction that caps the number of requests per second, with a limit of 2 requests/second.
* A concurrency restriction that limits the number of active requests at a given time. This restriction is less frequent than the rate restriction, but it may impact resource-intensive tasks. Consider these restrictions as upper bounds and avoid creating unnecessary demand. We may adjust restrictions to prevent abuse or increase limits for well-behaved high-traffic accounts.
