New Terminology Release API Endpoint

We are pleased to announce the publication of a new API endpoint for NLM terminology releases. This endpoint provides an updated list of releases for RxNorm, SNOMED CT, and UMLS. You can use this endpoint to completely automate the retrieval of the latest release files without having to manually download the files. For example, if you load RxNorm data weekly or monthly, you can monitor our release API and automatically download the data immediately when it becomes available.
