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
