EvidenceLens is a research tool — not medical advice. Open Payments lookups are computed from public records via fuzzy matching and may contain false positives. Always verify against primary sources.

Licensing

Licenses & attribution

EvidenceLens itself is MIT. Each upstream source keeps its own terms — we respect the most restrictive applicable license per record, and never serve full text where a source forbids it. Where a license is per-record, the document page links back to the original so you can check its specific terms.
