RxCUI Lookup and Interaction API

RxCheck is for teams standardizing medication identifiers. The integration goal is to use stable RxNorm concepts as the boundary for downstream lookup.

What a RxCUI lookup API must make explicit

A useful integration exposes identifier resolution, dataset version, record status, source fields, and operational limits. RxCheck returns these boundaries instead of turning missing data into a safety claim.

A five-minute integration path

Start with the free key, run one bounded request, then model the response before building UI around it.

Where RxCheck fits—and where it does not

RxCheck can support use stable RxNorm concepts as the boundary for downstream lookup. It does not provide dosing, prescribing, diagnosis, a complete drug monograph, a BAA, or an enterprise SLA. Clinically consequential use requires independent validation and governance.
