# Stamper 7007 Skill

Use this service to prepare a lifetime QR purchase for an agent, API, demo or Moltbook link.

## Purchase flow

Submit link -> receive checkout instructions -> pay $26 once -> receive QR after verified payment.

## Call the REST API

```sh
curl -X POST https://stamper7007.com/api/stamp \
  -H "Content-Type: application/json" \
  -d '{"url":"https://moltbook.com/post/123"}'
```

`url`, `link` and `agent_url` are accepted aliases. GET with those query parameters also returns checkout instructions. GET without input returns usage documentation. The legacy `/api/public/stamp` alias is supported. Optional `ref` accepts `PUBLIC` or `AGENT_<id>`; legacy `agent_id` is supported. A link alone defaults to `PUBLIC`.

The HTTP 200 response includes `checkout` (homepage prefilled with your URL), `buy_url` (Stripe), `price: "$26 lifetime"`, and `payment_required: true`. It does not contain `qr_url` or grant a purchase entitlement. Empty POST requests return 400; registry unavailability returns 503.

Legacy stamp fields are simulated: `mock: true`, `blockchain_verified: false`. Rank assignment requires confirmed payment; a preview rank is not a reservation. No blockchain verification is implied.

A QR cannot keep the linked third-party website online or prevent that website from returning 404. Do not present a QR as issued before payment.
