For Agents

Search and create FHIR-style Patient and Observation records to integrate clinical data exchange into a healthcare workflow.

Install Jentic One Beta

Connect the Open Health Hub API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Open Health Hub API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

Capabilities

What an agent can do with Open Health Hub API.

Search the patient register using FHIR-style query parameters such as identifier, name, or birthdate

Create a new Patient resource with demographic and identifier data for downstream clinical workflows

Retrieve a single Patient resource by ID for record review or clinical decision support

Use Cases

Patterns agents use Open Health Hub API for, with concrete tasks.

★ Remote Patient Monitoring Data Capture

A remote monitoring application can record blood pressure, weight, or symptom-questionnaire responses by POSTing Observation resources tied to a Patient. Because the schema is FHIR-aligned, the same payload can be relayed into a downstream EHR or analytics warehouse without remapping. New patients can be created via POST /Patient at enrolment time.

Create a new Patient with the supplied demographics, then POST an Observation resource for systolic blood pressure of 138 mmHg referencing the new patient ID.

Patient Lookup for a Care Coordination App

Care coordinators can search GET /Patient by identifier or name to find an existing record before creating a new one. Once found, GET /Patient/{id} returns the full demographic block used to populate a care plan UI. The FHIR-style response keeps the integration portable across other FHIR systems.

Search GET /Patient by identifier 'NHS:9876543210' and, if a record is returned, fetch GET /Patient/{id} to return the patient's name, date of birth, and gender.

Population Health Observation Reporting

Analysts running population-level reports can pull observations through GET /Observation filtered by code or date range to assemble a cohort view. The FHIR Observation shape carries code, valueQuantity, and effective date so downstream tools can compute trends without bespoke parsing.

Call GET /Observation with code=85354-9 (blood pressure) and a date range covering the last 30 days, then return the count and average systolic value.

AI Agent Clinical Data Exchange via Jentic

Clinical agents that read or write patient data can call Open Health Hub through Jentic so the X-API-Key never enters the prompt. Jentic returns the FHIR resource payload as a structured object and the agent can decide what subset to surface to the user, with full audit logging at the platform layer.

Use Jentic to search for 'find a patient by identifier in open health hub', execute GET /Patient with the identifier query, and return the matching Patient resource ID.

Key Endpoints

5 endpoints — open health hub exposes a fhir-shaped rest api for exchanging core clinical data between healthcare applications.

Why Jentic?

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

Credential isolation

The X-API-Key header is stored in the Jentic MAXsystem vault. Agents call the API by intent and never see the raw key, which is critical for clinical workloads where credential leakage is a compliance event.

Intent-based discovery

Agents search Jentic with intents such as 'find a patient' or 'record a vital sign' and receive the matching Open Health Hub operation with its FHIR-aligned schema, ready to execute.

Time to first call

Direct integration: 2-4 days to handle FHIR schema mapping, key management, and error handling. Through Jentic: under 1 hour.

FAQs

Specific to using Open Health Hub API through Jentic.

What authentication does the Open Health Hub API use?

API key authentication via the X-API-Key request header. Through Jentic the key is stored in the MAXsystem vault and injected at request time, so it is never exposed to the agent or logged in clear text.

Can I record patient vital signs with the Open Health Hub API?

Yes. POST /Observation accepts a FHIR Observation resource referencing a Patient, including code, valueQuantity, and effectiveDateTime fields. This is the standard path for vitals, weight, and questionnaire responses.

What are the rate limits for the Open Health Hub API?

The published spec does not state a hard rate limit. Treat the API as fair-use, batch large patient or observation imports, and contact Open Health Hub for production-grade quota agreements before high-volume use.

How do I search for a patient by identifier with the Open Health Hub API through Jentic?

Search Jentic for 'find a patient by identifier in open health hub', load GET /Patient, and execute it with an identifier query parameter (e.g. NHS:9876543210). Jentic adds the X-API-Key header from the vault.

Is the Open Health Hub API FHIR-compatible?

The resource shapes for Patient and Observation follow FHIR conventions, so payloads can be relayed into FHIR-compliant EHRs and analytics systems with minimal mapping. Verify the exact FHIR version against the Open Health Hub developer documentation before relying on niche elements.

What clinical resources are available through the Open Health Hub API?

The current spec exposes Patient (search, create, get) and Observation (search, create), totalling 5 endpoints. Other FHIR resources are not part of this OpenAPI surface.
