UNFAIRShip evidence-backed supplement intelligence inside your app.
Ranked shortlists, product packs, safety screens, and audit trails — from a single REST API.
Creatine Monohydrate
We shape the research. You ship the experiences.
Five ideas to start.
Pass an outcome ID, receive ranked interventions with score breakdowns, grades, and study counts. Drop the array into a chooser and ship.
built with/health-outcomes/{id}/ranked-interventions
Dose, safety, evidence highlights, and related entities arrive together — no N+1, no orchestration.

Alpha-GPC
Choline donor · nootropic
Send candidate + medications + conditions. Get a clear, warn, or block decision — with reasons — before the order, prescription, or plan goes through.
built withPOST /safety/screen
Clear
Ibuprofen · no known interaction
Block
Sertraline (SSRI) + 5-HTP — serotonin syndrome risk
Warn
Recommend prescriber sign-off if continuing
Walk the supplement ↔ outcome graph with graded edges and effect estimates. Power 'why this supplement?' pages your competitors can't.
built with/evidence · /evidence-links
Subscribe to classified releases and diffs. Invalidate only the affected entities, and keep an audit trail your compliance team can sign off on.
built with/releases · /changelog · /diffs · /snapshots
Every endpoint returns deterministic JSON with a versioned contract, cursor pagination, and x-library-version headers you can cache against. Grouped below by what your app is actually trying to do.
