API live — 330+ canonical drug records seeded

Drug normalization API for
telehealth teams

Messy free-text in → canonical RxNorm/NDC out. One call returns the canonical code, dosage form, lay description, and cited interaction evidence — everything you lost when RxNav DDI shut down.

Why RxBridge

Everything your med stack needs, one endpoint away

Built for post-seed telehealth and e-prescribing teams who can’t afford FDB but need something better than raw openFDA labels.

🧪

Fuzzy normalization

Resolves misspellings, abbreviations (HCTZ, MetXR), and free-text dose noise that exact lookup misses. Returns confidence score + ranked alternates.

📋

Canonical RxNorm / NDC

330+ seed records today, growing. Every match returns RXCUI, NDC, ingredient, brand, dosage form, and strength — ready to store.

💬

Lay descriptions

Plain-English patient-friendly summaries for every canonical drug. Explicit source field — never a black box. Degrades gracefully to null.

⚠️

Cited interaction evidence

DDI pairs with severity tags (minor / moderate / major), cited source identifier + snippet, and a mandatory not-medical-advice disclaimer. Evidence, not verdicts.

⚡

One-call combined endpoint

POST a list of messy texts, get back canonical codes + lay descriptions + interaction evidence in a single round-trip. Replace four separate API calls.

🔑

Self-serve API keys

Signup form → instant key. Free tier with monthly quota, paid tiers for volume. Usage meter visible in your dashboard. No sales call needed.
