Terms of Service

In order to avoid overloading the Indexing Initiative servers, NLM requires that users conform to the following restrictions:

Requests that exceed these limits may not be serviced and IP addresses will be blocked from further use of our tools. Service will not be restored until you contact us directly. This policy is in place to ensure that the service remains available and accessible to all users.

If you have a specific use case that requires you to send a large number of requests to one of our interfaces or Web API, and thus exceed the request rate limit outlined in this policy, please contact us prior to beginning. NLM staff will evaluate your request and determine if an exception may be granted.

We invite you to develop computer and mobile applications using National Library of Medicine (NLM) resources. We request that any application that makes use of NLM data include the following statement:

"This product uses publicly available data from the U.S. National Library of Medicine (NLM), National Institutes of Health, Department of Health and Human Services; NLM is not responsible for the product and does not endorse or recommend this or any other product."

Developers may not use the NLM name and/or logo in conjunction with their applications.

DISCLAIMER: It is not the intention of NLM to provide specific medical advice, but rather to provide users with information to better understand their health and their medications. NLM urges you to consult with a qualified physician for advice about medications.
