Why Leyr

Everything you need to integrate EHRs

Leyr turns months of vendor-specific plumbing into one clean, consistent API - sandboxed, secured, and documented end to end.
  • 40+ EHR vendors
    Epic, Oracle Health (Cerner), TakeCare, Cliniko, DIPS, and more behind a single integration.
  • Unified data model
    Patients, appointments, notes, documents, and invoices - the same schema on every vendor.
  • Full-featured sandbox
    Realistic test data and per-vendor guides, with Leyr-provided credentials to start instantly.
  • Built on standards
    FHIR and HL7 aligned, with openEHR support where vendors expose it.
  • Secure by design
    EHR credentials are encrypted with your own key that we never store - even we cannot see them.
  • AI-ready
    MCP servers for the docs and the live API - let your assistant write the integration.
One API, all EHR Systems
Connect to Epic, Oracle Health (Cerner), TakeCare, Cliniko, DIPS, and more through a single unified API. Adding a new EHR is configuration, not a new codebase.
A REST API developers actually enjoy
Get patient data, add medical notes, book appointments, pay invoices - clear endpoints that work consistently across all EHR vendors, backed by an interactive OpenAPI reference.
# Get patient data
GET /patients/{patient_id}

# Book an appointment
POST /appointments

# Add medical note
POST /medical-notes

# Get available time slots
GET /timeslots
Test against real EHR data models
Every vendor ships with dedicated test data, patient IDs, and step-by-step guides. Start instantly with Smart Mock and Leyr-provided credentials - bring your own EHR when you are ready.
