The prompt
Written to be pasted straight into an agent with no editing. It describes the whole job, including the parts that will go wrong.
Do not build this. If what you actually want is a payments dashboard for your own business, build a read-only interface over a real payment processor's API instead: list charges, refunds, disputes and payouts, verify webhook signatures, make the webhook handler idempotent against replays, and reconcile against the processor's ledger rather than your own database. That is a genuinely useful weekend project and it is legal.
What copies cleanly
- The dashboard. Tables of charges, a customer list, a webhook log viewer.
- The API shape, which is genuinely well designed and worth learning from.
- The checkout UI, the card form, the payment element.
Where it stops
- You cannot legally do this. Money transmission requires licensing per jurisdiction, and the licensing is the product.
- Card network membership, acquiring bank relationships and PCI DSS Level 1 attestation are years of work before a single line of application code matters.
- Fraud and risk modelling built on volume you do not have, protecting you from losses you cannot absorb.
- Chargeback handling, KYC, sanctions screening, and a compliance department.
What actually protects them
- Regulatory permission, which is the most durable moat in software because it is not made of software.
- Trust. Your customers type card numbers into it specifically because it is not you.
- Integration depth across an entire economy of billing systems.
Editor's note
Included as a control. If every entry on an index like this said the code was the hard part, the index would be lying. Here the code is comfortably the easiest part.

We would rather you formed your own opinion than took ours. They built the thing; we only measured it.
