I built a store that sells software to AI agents (and the storefront is a Cloudflare Worker)

Description and use

The author built a sovereign storefront selling software seeds to AI agents, leveraging Cloudflare Workers, Stripe, and Resend. The system handles checkout, webhook verification, KV storage, and a personal vault for product delivery.

Problem

Digital product stacks often bundle storefront, delivery, and customer relationship, taking a cut of sales. The author wanted a sovereign solution that keeps control over the storefront, checkout, and delivery while minimizing fees.

Outcome

The author successfully built a sovereign storefront that sells software seeds to AI agents, handling checkout, delivery, and customer access without platform fees. The system is live and has customers, but has not yet attracted traffic.

Workflow

• 1. Buyer visits the storefront (Cloudflare Worker) and selects a product.
• 2. Checkout is performed via a plain Stripe payment link that includes the product code as metadata.
• 3. Stripe creates a payment intent and sends a webhook to a second Cloudflare Worker.
• 4. The webhook Worker verifies the Stripe signature, writes the buyer’s Customer Access Record to KV, and sends a magic link email via Resend.
• 5. The buyer clicks the magic link to access their personal vault portal.
• 6. The vault streams product files from R2 or grants private GitHub repo access, respecting per‑product quotas.

Evidence

The Grand Bazaar (thefortthatholds.xyz) was built the other way — sovereignty first:

Checkout: plain Stripe payment links. The trick is in the metadata: each link carries a product code (access ID), mirrored into the payment intent.

Delivery: a Stripe webhook lands on a second Worker, which verifies the signature, writes the buyer's Customer Access Record to KV, and emails a magic link (Resend) to a personal vault — a portal where everything the buyer owns lives, with per-product quotas.

The products are "Selfware seeds": the code behind several of them is free and MIT-licensed on GitHub (Fortmail, Beta Reader, Fort Kitchen). The paid seed is a single readable file — the route — that you hand to your own AI agent to set the system up on your own accounts.
