Built a consent proof API — is this actually useful?

Built a consent proof API — is this actually useful?
I just launched ConsentProof. It's an API that records consent events with cryptographic hashes and generates PDF receipts.

User agrees to something → you call the API → we store an immutable, hashed record → you can generate a PDF receipt anytime for audits or disputes.

Basically: proper audit trail instead of just a row in your database.

Is this something you'd actually use?
