## Rate Limits EGYM MMS API v2 has a rate limiter against bursts of incoming traffic to help maximize its stability. **API allows 60 requests per 10 seconds for the given [API Key](/mms-api-v2/authentication)** In other words, if in a given window of 10 seconds we already received 60 requests for the given API Key then the next request will be rejected with status code `429` (see [Client Error Codes](/mms-api-v2/errors#429-too-many-requests) for details)
