Public surface / Payer Patient Access APIs
Quartz Patient Access API
This endpoint declares a complete, interoperable public surface.
Observed surface
- Base URL
https://epicproxy.hosp.wisc.edu/FhirProxy/UWHEALTH/api/FHIR/R4- Category
- Payer Patient Access APIs
- Availability
- answered 30 of the last 30 daily checks (100%)
- Last answered
- 2026-10-03 (answered on this run)
- Vantage agreement
- reachable from all 3 vantages, which are 3 hosts on one network (github-actions): one network's view sampled 3 times, not 3 independent networks
What each vantage saw
| Vantage | Result | What it saw | Condition |
|---|---|---|---|
github-actions/macos-latest | reached | answered in 266 ms | HTTP 200 |
github-actions/ubuntu-latest | reached | answered in 861 ms | HTTP 200 |
github-actions/windows-latest | reached | answered in 905 ms | HTTP 200 |
Vantages on one network are one network’s view sampled several times. A rule applied to that network’s address space reaches every one of them at once and reads exactly like agreement.
Interpretation
A grade describes two public discovery documents at one point in time. It does not inspect patient data, authenticated behavior, or clinical quality.

Declared app-to-server access
What the endpoint's own documents declare about app-to-server access, observed on this run. Nothing here was requested or exercised, and none of it is graded. An absent field is reported as absent, not as a refusal: a document that does not mention a field has not said anything about it.
| Question | Answer | What the document says | Where it is declared |
|---|---|---|---|
| Declares private_key_jwt client authentication at the token endpoint | declared | token_endpoint_auth_methods_supported lists private_key_jwt among 3 | SMART discovery: token_endpoint_auth_methods_supported |
| Declares the client_credentials grant, which SMART Backend Services uses | declared | grant_types_supported lists client_credentials among 5 | SMART discovery: grant_types_supported |
| Declares the client-confidential-asymmetric capability | declared | capabilities lists client-confidential-asymmetric among 17 | SMART discovery: capabilities |
| Declares system-level scopes | not listed | none of 5 scopes_supported is a system/ scope | SMART discovery: scopes_supported |
| Declares an export operation | not listed | 3 operations are declared and none is named export | CapabilityStatement: rest.operation and rest.resource.operation |
| Instantiates the Bulk Data Access implementation guide | declared | instantiates http://hl7.org/fhir/uv/bulkdata/CapabilityStatement/bulk-data | CapabilityStatement: instantiates |
Registry provenance
How this entry was verified
base URL printed in the plan's own table (Data Type | FHIR Server Base URL | API Documentation) at https://quartzbenefits.com/contact-quartz/interoperability-apis/, row 'Claims and other member data via the Patient Access API'. Caveat recorded rather than resolved: the host and its /UWHEALTH/ path segment belong to UW Health, a part-owner health system, so the same Epic instance may also serve that system's EHR data; the plan's own label is the basis for treating this as the payer surface. Live CapabilityStatement retrieved (recorded 2026-09-04). No later re-check is recorded, so the date above is the last time anyone checked this entry against the live endpoint.
