Use Cases

Patterns agents use Epic on FHIR API API for, with concrete tasks.

★ AI Agent FHIR Data Retrieval

AI agents access Epic patient data through Jentic using FHIR R4 resources without manually configuring Epic's authentication or endpoint discovery. An agent searches for 'retrieve patient from Epic' and Jentic returns the Patient resource schema with required parameters. The agent executes the query and receives standardized FHIR JSON, enabling health data workflows across Epic's network of hospitals and clinics.

Search for patient John Smith by name using GET /Patient with family=Smith and given=John, then retrieve their latest hemoglobin lab observation

Patient Record Lookup

Search and retrieve patient demographics from Epic-connected health systems using standard FHIR search parameters. The Patient resource supports search by name, date of birth, identifier (MRN), gender, and address. Results return full FHIR R4 Patient resources with telecom, address, and managing organization details for care coordination.

Search for patients with last name 'Garcia' and date of birth '1985-03-15' using GET /Patient, then retrieve the full record for the matching patient ID

Clinical Observations and Lab Results

Query Observation resources to retrieve lab results, vital signs, and other clinical measurements for a specific patient. FHIR Observations are categorized by type (laboratory, vital-signs, social-history) and include value, units, reference ranges, and interpretation codes. Supports date range filtering for longitudinal clinical trend analysis.

Retrieve all Observation resources of category 'laboratory' for patient ID abc123 from the last 90 days and list any values flagged as abnormal

Medication History Review

Fetch active and completed medication requests for medication reconciliation and drug interaction checking. The MedicationRequest resource includes drug name, dosage instructions, prescriber, dispensing pharmacy, and status. Supports filtering by status (active, completed, stopped) for current medication list generation.

Get all active MedicationRequest resources for patient ID xyz789 and list the drug names, dosages, and prescribing providers

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Epic API keys and SMART on FHIR tokens are stored encrypted in the Jentic vault (MAXsystem). Agents receive pre-configured authorization headers — raw credentials and client secrets never enter the agent's context.

Intent-based discovery

Agents search by intent (e.g., 'retrieve patient labs from Epic') and Jentic returns matching FHIR resource operations with their query parameter schemas, so the agent can construct the correct request without navigating Epic's FHIR documentation.

Time to first call

Direct Epic integration: 2-4 weeks for app registration, credential setup, and FHIR endpoint configuration per organization. Through Jentic: under 1 hour — search, load schema, execute.

FAQs

Specific to using Epic on FHIR API API through Jentic.

Why is there no official OpenAPI spec for Epic on FHIR API?

Epic does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call Epic on FHIR API via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.

What authentication does the Epic on FHIR API use?

The Epic on FHIR API uses an API key passed in the Authorization header. In practice, Epic implementations typically use SMART on FHIR (OAuth 2.0-based) for production access with client credentials or authorization code flows depending on the app type. Through Jentic, credentials are stored in the MAXsystem vault and agents receive pre-configured authorization headers.

Can I retrieve lab results with the Epic on FHIR API?

Yes. The GET /Observation endpoint returns clinical observations including lab results when queried with category=laboratory and a patient reference. Results include LOINC codes, numeric values with units, reference ranges, and interpretation flags (normal, abnormal, critical).

How many patient records can I access through Epic on FHIR?

Epic's network serves over 305 million patient records across connected hospitals and health systems. Access depends on your application's registration with individual Epic organizations. Each organization grants access to their patient population through the FHIR endpoint.

How do I search for a patient through Jentic?

Search Jentic for 'look up patient in Epic' to discover the GET /Patient endpoint. The agent loads the schema which accepts search parameters like family (last name), given (first name), birthdate, and identifier (MRN). Install via pip install jentic and use the search-load-execute flow to query without manual configuration.

What FHIR resources does the Epic on FHIR API support?

This spec covers Patient (demographics and identifiers), Observation (labs, vitals, social history), and MedicationRequest (prescriptions and medication orders). These three resources cover the core clinical data retrieval use cases for patient-facing and provider-facing applications.
