med-attest is a patient-controlled consent broker for AI tools reading EHR data. Sign up, checkout, get a DID — your tool authenticates against the broker and reads patient data under signed grants. Every call lands a cryptographic receipt the patient can verify.
Stripe checkout → Ed25519 keypair → broker allowlist → welcome email. No sales call, no manual approval.
Patients authorize via a PWA wallet — every grant is a W3C VC they signed and can revoke. Your tool sees only what the patient said yes to.
Every tool call lands a broker-signed receipt batched into a Merkle tree and anchored on Cheqd. Auditors verify independently.
