# Billing

> How checkout, keys, and invoices work — Zuplo Developer Portal, then Stripe.

When you subscribe, you leave **geometry.app** on purpose. Keys and quotas come from our **Zuplo** Developer Portal. Card checkout, invoices, and cancel run on **Stripe**. We do not store full payment card numbers.

<Note>
  This is the usual pattern for a hosted API: the product site explains the plan; a payment processor takes the card; a gateway issues the key. Same hop as [geometry.app/pricing](https://geometry.app/pricing/).
</Note>

## Checkout path

1. Open **[Pricing](https://geometry.app/pricing/)** (or follow an upgrade link after a quota `429`).
2. **Upgrade** / **Get a Free sandbox key** opens the **official Zuplo Developer Portal** (same URL as below). Create the portal account, pick a plan, and subscribe.
3. **Stripe Checkout** collects the card. After pay, the portal shows your subscription and a raw key (`zpka_…`).
4. Paste the key onto the branded MCP URL — [Where your key goes](/connect-and-keys). The tool URL stays `https://mcp.geometry.app/mcp` (never a `*.zuplo.app` MCP host).

## Official Developer Portal

This is the production checkout host. **geometry.app/pricing** Upgrade and Get a Free sandbox key open the same page. The hostname is assigned by Zuplo. It is the official portal, not a lookalike.

https://geometry-main-bf0a4d2.zuplo.site/pricing
```

<Note>
  `geometry-main-bf0a4d2.zuplo.site` is Zuplo's assigned Production Developer Portal. That vendor host is expected. It is **not** the MCP tool URL. Do not use `*.zuplo.app` for tools — that was a temporary gateway host. Tools stay at `https://mcp.geometry.app/mcp`.

| Step                     | Who you see                        | What they do                                               |
| ------------------------ | ---------------------------------- | ---------------------------------------------------------- |
| Plan page                | geometry.app                       | Explains Free vs Starter; starts checkout                  |
| Official portal          | `geometry-main-bf0a4d2.zuplo.site` | Zuplo Production Developer Portal (same URL Upgrade opens) |
| Subscribe / key / usage  | **Zuplo**                          | Developer portal, API keys, quotas, MCP gateway            |
| Card / invoices / cancel | **Stripe**                         | Payment and Stripe Customer Portal                         |

You still call tools at **`mcp.geometry.app`**. Zuplo sits in front as the gateway; Stripe never appears on the tool URL.

## After you have a key

How-to for `?key=`, rotation, and cancel lives on [Where your key goes](/connect-and-keys). Billing card issues stay in the **Stripe** portal (opened from the Developer Portal).

## Lookups (not a public database)

Tool answers are **hosted Postgres lookups**. Builders call MCP/HTTP **tools** only — there is no public SQL console and no table REST API.

## Plans

Same tools and fields on every tier. You pay for **volume**, not features. Current prices: [geometry.app/pricing](https://geometry.app/pricing/).
