Epic on FHIR public sandbox: endpoint report
Everything this project observed about this one endpoint, everything it did not observe, and what would change the result. Free to read, link, print and hand on; there is nothing here behind a sign-in and nothing to buy.

What was observed, and what was not
This report covers 9 checks. 9 ran. 0 were asked from every reporting vantage and answered by none. 0 were never asked, because nothing was retrieved for them to read. The three are different facts and none of them is a zero: a check that did not run publishes no number, no mark against this endpoint, and nothing below to act on.
Reachability
| Check | State | What this run observed |
|---|---|---|
| R1 | Pass | /metadata answers with HTTP 2xx over HTTPS: 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 |
| R2 | Pass | /metadata responded in 391 ms (median across 3 reachable vantages on one network) |
Capability transparency
Interop readiness
| Check | State | What this run observed |
|---|---|---|
| I1 | Pass | US Core / CARIN / Da Vinci profiles declared in CapabilityStatement.instantiates, rest.resource.supportedProfile |
| I2 | Pass | SMART discovery document present and complete |
| I3 | Pass | OAuth/SMART security service declared in CapabilityStatement |
What each vantage saw
| Vantage | Result | What it saw | Condition |
|---|---|---|---|
github-actions/macos-latest | reached | answered in 225 ms | HTTP 200 |
github-actions/ubuntu-latest | reached | answered in 447 ms | HTTP 200 |
github-actions/windows-latest | reached | answered in 391 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.
What would change this
Nothing is listed here: every check that ran passed. Checks that did not run are in the section above, and they are not failures.
If this does not match what you see
Every number here describes two public documents at one moment, read from the vantages listed above. If it does not match what you serve, the difference is worth knowing.
Correct or dispute this record. There is no sign-in, no fee, and nothing to buy: this report is free to read, link, print and hand on, and this project collects nothing about the people who read it.
Where this came from
live CapabilityStatement fetch on fhir.epic.com; software identifies as 'Epic May 2026' (recorded 2026-08-05). Re-checked 2026-08-19: live CapabilityStatement re-fetch from the davis-ca residential vantage; fhirVersion 4.0.1, 60 resource types, publisher 'no publisher field', software 'Epic August 2026'.
The same run, as data: this endpoint's JSON, what its CapabilityStatement declares, resource by resource, and every observation on record for it, with the dates it answered and the dates it did not.
This is an observational snapshot of a public, unauthenticated surface. It is not an audit, a ranking of care quality, or a statement about anyone's regulatory compliance. Grades are comparable within a category only. See how we grade.
