APIs

Application Program Interfaces (APIs) are available to users to retrieve data from several drug information sources, including RxNorm, MED-RT and RxTerms. Currently these APIs are available:

The APIs are also available as part of RxNav-in-a-Box, which provides users with a locally-installable version of RxNav, RxClass, and the APIs.

The API resources can also be used interactively or in batch mode with RxMix.

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."
