# Rate Limits

A rate limit is the number of requests that a client application can make within a given time period.  Rate limits ensure that EBSCO maintains a high quality of service.  These limits help us provide the most reliable and scalable API for our partner developer communities.

# Rate Limits

* Live Rate Limit per Client Application - 5000 requests per minute
* Sandbox Rate Limit per Client Application - 5000 requests per minute

When a client application has reached their rate limit, Entitlement API will return an API response with an HTTPS Code of 429, Too Many Requests, with the following JSON body:

```json
{
    "fault": {
        "faultstring": "Rate limit quota violation. Quota limit  exceeded. Identifier : XjaumnhwfGpz0KqgrteDnDEGyoi",
        "detail": {
            "errorcode": "policies.ratelimit.QuotaViolation"
        }
    }
}
```
