Flexpa Endpoint Directory

Flexpa's directory is a comprehensive index of Payer Patient Access APIs and is the largest of its kind. The information is continuously generated from our live database of connected endpoints. The directory provides detailed information about each payer's connection status, authorization information, and FHIR API capabilities.

Endpoints are:

• FHIR-compliant REST API servers that implement the Patient Access API standard
• Protected by SMART on FHIR authorization flows
• Operated by health insurance payers to fulfill CMS Interoperability requirements

If you're a payer or vendor and would like to update your information or discuss testing partnerships, please reach out to us at interop@flexpa.com.
