# Create Da Project Checkout

`POST /api/v1/da-project/checkout`

## Request

- Base URL: `https://api.casaintelligence.com.au` (the document declares no server; this is the origin it was published from)

- Auth: HTTP bearer

Create a $1,999 Stripe checkout + a pending ci_tp_projects row.

Authenticated (§H.3.4): the website proxy forwards the applicant's session
JWT. The identity used downstream is the AUTHENTICATED one — a body that
names someone else's user_id/org is overridden/rejected, so a stolen or
replayed request cannot create projects under another account.
