# Introduction

# Introduction

**VeriflowAPI** is a high-availability REST API for verifying professional licenses across fragmented US government databases. One API call replaces days of manual credentialing.

## What VeriflowAPI does

When you submit a provider's details, VeriflowAPI simultaneously checks:

* **NPPES NPI Registry** — federal database of all licensed healthcare providers
* **OIG Exclusion List** — HHS list of excluded individuals from federal programs
* **State Medical Boards** — deep license status for TX, FL, IL, WA, CO, CT, and AL (more added by demand)

We normalize inconsistent data formats across all sources and return a single, clean JSON response in under 200ms — even when government sites are slow or down.

## Who uses VeriflowAPI

* **Telehealth platforms** verifying providers before onboarding
* **Credentialing software** automating provider enrollment workflows
* **Healthcare staffing platforms** screening candidates at scale
* **Insurance and compliance teams** running periodic license audits
* **Medical staffing agencies** validating contractor credentials
