Prices exclude the service fee. `buyable now` is a boolean, not a count —
remaining stock is the organizer's information and is not published; create
a checkout session to find out whether a given quantity fits.

## Buying this for a person

Two ways, depending on what you can do:

- You can pay with a Stripe Shared Payment Token: buy it yourself through the
  API (see "Buying this through the API" below, when this event has it).
- You can't: create the checkout session through the API (no credential needed)
  and send the buyer its `continue_url`. They pay there with a card, Apple Pay or
  Google Pay and no Gomry account.
  Or send the buyer the link for the ticket they want below. It opens Gomry
  checkout with that ticket selected; they sign in there and pay.

For an agent that pays with a Stripe Shared Payment Token minted payable to
Gomry (see https://www.gomry.com/auth.md#payment). The purchase finishes without the
buyer leaving your conversation.

No token? Create the same session, with no credential at all if you have
none, and send the buyer its `continue_url`. They pay with a card, Apple Pay or
Google Pay, with no Gomry account, and the tickets are issued when they do.

The `ticket type id` column above is `items[].id` below. This body is
complete and can be sent as it stands, with the buyer details replaced:

```
POST https://www.gomry.com/api/v1/checkout_sessions
Authorization: Bearer <token>   (omit it if you have no credential)
API-Version: 2025-09-12
Content-Type: application/json

{
  "items": [
    {
      "id": "external:ticketnetwork%3A1202778164",
      "quantity": 1
    }
  ],
  "buyer": {
    "name": "Ada Lovelace",
    "email": "ada@example.com"
  }
}
```

The response `totals` is the authoritative price — it includes the service
fee, which is not in the table above and depends on the cart and the
organizer's fee settings. Never compute a total from this document.

Quoting and `continue_url` need no credential. Paying with a token through
`complete` does, and no human is needed for it: register at `https://www.gomry.com/api/mcp/oauth/register`
for the `client_credentials` grant. Full flow: https://www.gomry.com/auth.md
