Receipt
Verifiable
Verifiable usage receipts for every billable AI request.
VaaS Ledger turns each chargeable request into a receipt customers can use for reconciliation, downstream billing, enterprise audits, agent payments, and dispute review.

Receipts that stay operator-usable
The point is not cryptography for its own sake. Each receipt must connect request, route, model, cost, billing, and trace data so finance, customer success, and security teams can use it.
- Bind request id, model id, route, fallback state, cost, timestamps, and execution metadata into one receipt.
- Keep plaintext prompts out of the verifier layer when customers only need proof of integrity.
- Use the same receipt surface across online inference, media tasks, and batch jobs.
Independent receipt verification
Customers can verify that a billable request receipt matches the request and ledger data they are reconciling.
- Expose receipt id, trace id, cost metadata, and verification status next to the request.
- Keep receipt verification independent from the running application.
- Optionally anchor references on-chain when external timestamp proof matters.
