Public surface / Payer Patient Access APIs
Cox HealthPlans Interoperability API
This endpoint declares a solid public surface with minor gaps.
Observed surface
- Base URL
https://api.coxhealthplanfhir.com/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 300 ms | HTTP 200 |
github-actions/ubuntu-latest | reached | answered in 691 ms | HTTP 200 |
github-actions/windows-latest | reached | answered in 484 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.

Findings
Declared capability changes
- 2026-10-02: software_version: '4.0.1 3.9.0 v1.0.0-rc+202607151200 bc93922' -> '4.0.1 3.11.2 v1.0.0-rc+202609291200 22bf7ee'
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.

Registry provenance
How this entry was verified
base URL published by the plan at coxhealthmedicareadvantage.com/interoperability/, which prints the capability-statement address and labels it as covering both the Patient Access and Provider Directory APIs; the base is that string minus /metadata. The page sits on the plan's Medicare Advantage domain but speaks throughout as Cox HealthPlans and its FAQ extends the rule to ACA marketplace coverage, which is this roster entry. Host is plan-branded rather than a vendor template. 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.
