Pro & Payments

The portal sells AI Cost Gate Pro as a one-time source-code purchase. There are no subscriptions and no recurring charges.

What you get

For a single $29 payment you receive:

• Full access to the private ai-cost-gate GitHub repository (collaborator role).
• The docker-compose deployment we ship.
• All updates within the v1.x line.
• 14-day refund window.

How checkout works

1. Click "Get Pro" on the Pro page.
2. The portal creates a pro_license row in the portal's database with status=pending.
3. The portal calls Creem's /v1/checkouts API with a success_url pointing back to /checkout/thanks.
4. Creem redirects the buyer to a payment page.
5. After payment, Creem sends a checkout.completed webhook to the portal.
6. The webhook handler:
   • Verifies the HMAC signature.
   • Marks the pro_license row active.
   • Calls GitHub's PUT /repos/{owner}/{repo}/collaborators/{username} to invite the buyer.
   • Sends a confirmation email to the buyer.
7. The buyer is redirected to /checkout/thanks and given a 14-day refund window.

Refund policy

See the Refund policy. Refunds within 14 days are honoured. The pro_license row is marked refunded and the GitHub invitation is revoked.
