Public surface / Payer Patient Access APIs
Cigna Patient Access API
This endpoint declares a complete, interoperable public surface.
Observed surface

- Payer Patient Access APIs
- Availability
- answered 58 of the last 58 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 418 ms | HTTP 200 |
github-actions/ubuntu-latest | reached | answered in 591 ms | HTTP 200 |
github-actions/windows-latest | reached | answered in 655 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
Observed since 2026-08-05; no changes to declared capability recorded.
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 | not declared: the field is absent | the document has no token_endpoint_auth_methods_supported | SMART discovery: token_endpoint_auth_methods_supported |
| Declares the client_credentials grant, which SMART Backend Services uses | not declared: the field is absent | the document has no grant_types_supported | SMART discovery: grant_types_supported |
| Declares the client-confidential-asymmetric capability | not listed | capabilities lists 5 and not client-confidential-asymmetric | SMART discovery: capabilities |
| Declares system-level scopes | not declared: the field is absent | the document has no scopes_supported | 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 | not listed | 0 canonicals are instantiated and none is Bulk Data's | CapabilityStatement: instantiates |
