Public surface / Payer Provider Directory APIs
Blue KC Provider Directory API
This endpoint declares a solid public surface with minor gaps.
Observed surface
- Base URL
https://bluekc.sapphirethreesixtyfive.com/fhir- Category
- Payer Provider Directory 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 3041 ms | HTTP 200 |
github-actions/ubuntu-latest | reached | answered in 2974 ms | HTTP 200 |
github-actions/windows-latest | reached | answered in 3280 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 | not retrieved on this run | the SMART discovery document was requested and not served on this run | SMART discovery: token_endpoint_auth_methods_supported |
| Declares the client_credentials grant, which SMART Backend Services uses | not retrieved on this run | the SMART discovery document was requested and not served on this run | SMART discovery: grant_types_supported |
| Declares the client-confidential-asymmetric capability | not retrieved on this run | the SMART discovery document was requested and not served on this run | SMART discovery: capabilities |
| Declares system-level scopes | not retrieved on this run | the SMART discovery document was requested and not served on this run | SMART discovery: scopes_supported |
| Declares an export operation | not listed | 0 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 |
Registry provenance
How this entry was verified
base URL printed as finished, non-sandbox request URLs across three worked-example pages on Blue KC's own developer portal, and as the Swagger link href on its Provider Directory page. Vendor is Sapphire Digital, named and linked by Blue KC, which prints the finished URLs rather than a template. The portal states the directory 'does not require a user authentication to use'. Live CapabilityStatement retrieved Grade instability recorded on the curation date: repeat probes returned different interop-readiness scores while reachability held, which means this host served different profile declarations on different requests. That is the alternation this project already names, and no single probe's letter is the whole picture. (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.
