The RentCast API has a rate limit of 20 requests per second.
Our API has a hard limit of 20 requests per second, per API key, regardless of your billing or subscription plan.
If you reach this limit, you will receive an error with a 429 status code and the following body:
{
"status": 429,
"error": "auth/rate-limit-exceeded",
"message": "The rate limit of 20 requests per second has been exceeded"
}
We recommend creating separate API keys for each of your applications or integrations, as well as throttling your usage to stay within this rate limit.
