# Agentic Commerce

> The commerce capabilities that let an AI application discover, quote, checkout, and pay.

Prava is more than a payment token. It provides the **commerce capabilities** an AI application needs to
turn an intent to buy into a completed order: discovering products, pricing them accurately, and
completing a real checkout on the merchant's site.

## The capability pipeline

```mermaid theme={null}

    D["Discover<br/>UCP search & catalog"]
    Q["Quote<br/>live price, reconciled"]
    C["Checkout<br/>Browser Harness"]
    P["Pay<br/>one-time tokenized card"]
    D --> Q --> C --> P
```

Two capabilities do the heavy lifting, and they work as a pair:

<CardGroup cols={2}>
  <Card title="UCP" icon="magnifying-glass" href="/integration/ucp">
    Search products, read catalogs, and open quotes across participating Shopify merchants via the
    Universal Commerce Protocol.
  </Card>

  <Card title="Browser Harness" icon="robot" href="/integration/browser-harness">
    Prava's checkout automation confirms the true total from a UCP quote and completes the real merchant
    checkout.
  </Card>
</CardGroup>

## Who this is for

AI applications and agents that want to **find and buy** on a user's behalf rather than only
process a payment. These same capabilities power [Prava Pay's agentic shopping](/prava-pay/shopping)
(`prava shop search → product → quote → checkout`); this section explains what's behind those commands.

<Note>
  Whichever surface you use, the card is always collected on Prava's secure surface and turned into a
  one-time, merchant-scoped credential; the AI application never handles a raw card.
</Note>

## How the pieces fit

<Steps>
  <Step title="Discover with UCP">
    Search across participating Shopify merchants and read product/variant details. See
    [UCP](/integration/ucp).
  </Step>

  <Step title="Quote the real price">
    UCP opens a checkout for an initial price; the [Browser Harness](/integration/browser-harness)
    reconciles it against the live checkout so the amount is correct before anyone commits.
  </Step>

  <Step title="Complete checkout">
    The Browser Harness fills the checkout, confirms the final total, pays with the one-time token, and
    returns a verifiable order.
  </Step>
