Live validation · FHIR R4

Try the validation cascade.

Paste a FHIR R4 resource or Bundle and run it through the live API—the same POST /v1/validate endpoint, across all eight layers. Pick an example to see conformant, non-conformant, and clinically impossible results.

Use synthetic data only. Requests are proxied to the live service and dropped after scoring—never stored—but this is a public sandbox. Do not paste real PHI.
