Search-param builder

Pick a resource, check the search params you want, and Run the assembled query against your sandbox. Date params support the FHIR comparison prefixes (eq, gt, ge, lt, le).

No sandbox token set

Get one from the "Open the playground" link on your key-reveal page, or paste a sandbox token here. Never a production key — sandbox keys are verified before they're saved, and a production key is rejected. Once verified, it's stored in sessionStorage on this origin and sent with every request this page runs. See Sandbox quickstart if you don't have one yet.
