# Create Credit Pack Checkout

`POST /api/billing/credits/checkout`

One-time Stripe Checkout to buy a prepaid credit pack (PAYG tier).

Unlike the subscription checkout, this is ``mode="payment"`` — a single
charge of ``credits × $0.15`` with no recurring plan. The card is collected
here (a PAYG org needs none until its first purchase). Multiple concurrent
purchases are legitimate, so this does NOT use the one-subscription-per-org
single-flight guard; a Stripe idempotency_key guards double-clicks and the
webhook credits the ledger idempotently via a UNIQUE stripe_ref.
