One API for drug information, supplement data, and interaction checks. Built for healthtech developers.
A single API call gives you structured drug and supplement data from authoritative government sources.

Comprehensive drug and supplement data from authoritative sources, delivered through a modern API.
Search 100,000+ drugs by name, RxCUI, or NDC code. Get labels, dosage forms and active ingredients from authoritative FDA sources.
120+ supplements with dosages, interactions, and evidence ratings. Sourced from the NIH Office of Dietary Supplements for reliable, evidence-based data.
Drug-drug and drug-supplement interaction checks. Drug-drug data comes from FDA drug labels (openFDA) plus a curated set of major interactions; drug-supplement data from FDA label text and the NIH supplement records. Severity ratings on curated interactions and labeled clinical detail included. Supplement-supplement coverage is limited, and the assess endpoint reports it per pair as not covered rather than as no interaction found.
All data comes from free, publicly available U.S. government health databases. No proprietary data, no licensing fees.
Drug labels and the NDC directory from the FDA's public API.
Normalized drug naming and RxCUI identifiers from the NLM.
Dietary supplement fact sheets with dosage, safety, and interaction data from the NIH Office of Dietary Supplements.
Start free, scale as you grow. No hidden fees, no long-term contracts.
Every plan includes every endpoint, including stack checks up to 100 items. Plans differ in monthly queries, rate limit, license and support.
Each data request (a search, lookup, interaction check or assessment) is one query. Usage, billing portal and health checks are free. Batch requests count one query per name or pair, and stack checks above 10 items add a quarter query per additional item, rounded up once, so a 40-item stack is 9 queries.
When a key reaches its monthly quota, further requests return 429 until the month resets at 00:00 UTC on the 1st. A stack or batch request made while quota remains is served in full, even if it takes usage past the quota (a stack by up to 23 queries). No overage charges.
Enterprise: Need more than 100,000 queries a month or custom terms? Contact us →
250 queries per month, no credit card required. Your key shows up right here, once, so copy it when it appears. We'll email a confirmation too, but the key itself is never emailed.
MedData runs as an MCP server, so Claude, Cursor, and LangChain agents can call it directly. Install it with one command, or connect the hosted server on Smithery. Agents can self-onboard too: the free signup returns the key in the response.
