Sign in with Medicare (sandbox)
We connect to sandbox.bluebutton.cms.gov — CMS's official developer sandbox — and pull a synthetic beneficiary's claim history. Nothing real, nothing stored. You'll see the same Claire Simulation dataset every demo.
Sign in with MedicareSandbox only — no real beneficiary data
What we do with the data: read Patient + Coverage + ExplanationOfBenefit (read-only), match one claim line to your uploaded MSN, pre-fill Form CMS-20027, and hand you a printable packet. Session is 60 minutes, cookie-only, cleared on tab close.
