01 / What it does

A prepaid-credits ledger for AI products.

  • 01

    Spend with the work

    Credits are debited inside the same database transaction as the work, so a failed spend rolls the work back too.

  • 02

    Safe by default

    Live Stripe keys are refused until you opt in, and webhook signatures are verified before any grant.

  • 03

    Append-only

    Balances are the sum of append-only entries, with idempotent retries, refunds and clawbacks.

02 / The record

What it can prove, and where it stops.

Proven safeguard
Live Stripe keys are refused until you opt in, and a balance cannot go below zero, even under concurrent requests.
Limits
Version 0.x and experimental: a real Postgres test suite, but no external audit and little production volume yet. It is a single-entry ledger, Stripe is the only payment adapter, and tax and invoicing are yours.
