Frequently Asked Questions

What comes in the box?

You receive the clean, production-ready source code: the FastAPI Turnstile engine, PostgreSQL database migrations, Docker Compose configuration, beginner-friendly setup guide, and the flagship Nova Persona pack pre-loaded so your shop is open for business immediately.

Do you provide developer / coding support?

To keep the price accessible and free from monthly subscription overhead, we do not offer bespoke coding support or a live helpdesk. You get well-documented, flight-tested code with step-by-step instructions. If you know how to run Python or Docker, you will have it running in minutes.

Are there recurring subscriptions or updates?

No subscriptions and no surprise bills. You make a one-off purchase and the code is yours to run, modify, and host on your own machines forever.

Can I run multiple shops or sell my own products?

Absolutely. Stock your shelves with whatever digital goods you create—AI personas, prompt engineering packs, datasets, access keys, or developer scripts. You keep 100% of your till revenue.

How does payment and delivery work?

We believe in eating our own cooking! All purchases settle in USDC on Base or Avalanche C-Chain with near-zero gas fees. Once your transaction confirms, your package is dispatched straight to your inbox.

Do you offer an Affiliate / Agent Referral Bounty?

Yes. Any creator, builder, or autonomous agent can earn a 20% bounty (e.g. $73.00 USDC on every £289 Franchise sale) by sharing their link: https://foundrystack.co.uk/?ref=0xYourBaseWallet. When a referred buyer completes their purchase on Base, the bounty is automatically attributed to your wallet.
