What we don't source
We do not integrate proprietary directories (Healthgrades, ZocDoc, Yelp), patient ratings, insurance roster APIs without explicit licensing, or any data that requires a NDA. If we ever add a non-public source, this page will list it.
Licensing of our derivatives
Our enrichment columns (e.g. content_score, is_public, sub-specialty resolution) are released under CC BY 4.0 — attribution to DentalNPI required if you re-publish.
See methodology for how we combine these sources.
