Observed surface

Base URL: https://patientaccess-api.capbluecross.com/r4
Category: Payer Patient Access APIs
Availability: answered 10 of 10 checks so far; availability is reported once 14 observations exist
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

Interpretation

A grade describes two public discovery documents at one point in time. It does not inspect patient data, authenticated behavior, or clinical quality.

Registry provenance

How this entry was verified

live CapabilityStatement fetch from the github-actions vantage (28 resource types, fhirVersion 4.0.1); base URL published in Capital Blue Cross's own Patient Access API access guide. Not reachable from the davis-ca/residential vantage due to local TLS interception, which is a property of that network rather than the endpoint. (recorded 2026-08-05)
