General
What professions does VeriflowAPI currently support?
VeriflowAPI currently supports medical doctors (MD and DO) in all 50 US states via NPPES and OIG, with deep state-level data for California, Texas, New York, Florida, and Illinois. Nursing, pharmacy, mental health practitioners, and contractor licenses are in development. Email support@veriflowapi.com to request priority support for a specific profession.How accurate is VeriflowAPI?
VeriflowAPI pulls directly from authoritative government databases — NPPES, OIG, and state medical boards. Accuracy is as good as the source data. We normalize and validate data on ingestion to reduce errors from inconsistent source formatting. For high-stakes decisions, we recommend using both NPI and DOB in your request to maximize match accuracy.Can VeriflowAPI verify providers in all 50 states?
Yes, for basic NPI and OIG screening. For full state-level license status — including expiry date and disciplinary history — we currently support the Big 5 states: California, Texas, New York, Florida, and Illinois. Additional states are being added based on customer demand.Do you support international license verification?
Not currently. VeriflowAPI is focused on the US market. Canada and UK are on the roadmap for 2027.Technical
What happens if a government site is down?
VeriflowAPI serves cached data when a source is temporarily unavailable. The response will include"cached": true and "source_live": false. The cache_expires_at field tells you when fresh data will next be attempted.
Our 99.9% uptime SLA covers our API availability, not the availability of individual government source sites.
How do I know if my result is from cache or live?
Check thecached and source_live fields in the response:
What does verified: false mean exactly?
verified: false means one of the following:
- Provider was not found in any checked sources (
status: "not_found") - License status is not active (
status: "inactive","suspended","expired", or"revoked") - Provider is on the OIG exclusion list (
oig_excluded: true)
status and oig_excluded fields for the specific reason.
Can I use VeriflowAPI for non-medical professions?
Not yet. Medical doctors are the current focus. Nursing, pharmacy, legal, and contractor licenses are in active development.What is the difference between disciplinary_flags and oig_excluded?
disciplinary_flags: truemeans the provider has disciplinary actions on record with their state medical board. This could be a warning, probation, or other board action. It is a signal that requires human review — not necessarily a disqualifier.oig_excluded: truemeans the provider is on the federal HHS exclusion list. This is a hard disqualifier. You cannot employ or contract with this provider if you receive federal healthcare funding (Medicare, Medicaid).
