Stanford Authorized Users are collectively allowed 24,000 Searches / 1,200,000 Documents annually.  These limits are University wide; searches from either of Stanford access credentials count against these limits, and it only resets at the start of each calendar year.  We ask you to be conscientious and courteous with your usage of the API, since your use of the API counts against these overall limits for other users.

Use Nexis Uni and the LexisNexis Web Services API User Interface to refine and optimize your search query ahead of time, as this does not count against the University wide usage limit.  We strongly encourage you to review Getting Started with the API while waiting for API access to be granted.

In addition to the University’s overall annual limit, LexisNexis imposes a throttle on searches, limiting the amount of content that can be accessed each minute, hour, and day.

The LexisNexis API throttle limits are:

• 5 searches per minute
• 200 searches per hour
• 1000 searches per day

Each credential is also limited to accessing 50,000 documents per day.  As users approach throttle limits, they may notice reduced performance.

A single "search" is equal to fifty (50) documents. A search that exceeds 50 documents will count as multiple searches. For example, a search that retrieves 150 documents will be counted as 3 searches.

A “document” is defined as the metadata and/or full-text of a news article.
