Every field traces to an official record.
Our outward data is built from authoritative records — not star ratings, not ads. Each field carries the source it came from and the date we checked it, so you can stand behind what you build on it.
The official U.S. registry of healthcare providers. Anchors a provider’s identity and NPI.
Certification status for healthcare and telehealth merchants. Shown only with a verification date.
Active professional licensing on file, attributed per state. Reported vs. board-verified is labelled distinctly.
Screened against FDA warning letters. A provider is “clear” only when we’ve run the screen; “flagged” when a letter is on file.
Official quality and certification data for applicable verticals (e.g. senior care). Added per vertical as coverage expands.
Merchant-submitted
Pricing and service details a provider submits through a claim. Always labelled provider-reported until independently verified.
What we won’t do
- No platform scraping in outward fields. Third-party directory ratings never become an outward xcircl fact.
- No invented values. A field we can’t source is returned empty or “not yet verified” — never filled by a model.
- Verified means verified. A signal is only marked verified when we hold both a source and a verification date.
Source-data migration is ongoing. We describe our method and sources here; we publish specific verified-coverage figures on the coverage page as they grow, rather than overclaiming today.
