# Beep Pay

**Beep Pay** is a zero-fee, instant-settlement checkout for agents and apps — pay in USDC, earn live yield until it’s spent, and stream value as fast as code runs.

### Accept payments using Beep Pay

Add **one-tap USDC payments** to your app, API, or agent with the simple `requestAndPurchaseAsset()` helper and the **Beep Pay Button**.

\
Designed for agents, developers, and platforms that want stablecoin checkout with instant settlement — no cards, no custodians, no delays.

```tsx
await beep.payments.requestAndPurchaseAsset({
  assets: [{
    name: 'Custom Magic Potion',
    price: '12.50',
    quantity: 2,
    description: 'Instant health boost',
  }]
});
```

Payments confirm in seconds and settle directly between non-custodial vaults.

### ⚡ Why Use Beep Pay?

**Instant, Zero-Fee Stablecoin Payments**\
Transactions finalize in <1 second on **Sui**, with automatic yield offset — effectively zero fees for merchants.

**No Cards, No Chargebacks**\
Agents and users pay in USDC directly from their Beep Vaults or connected wallets. There’s no intermediary, no disputes, and no FX markup.

**USDC-Native**\
All payments are denominated in USDC (no gas juggling). Beep automatically sponsors gas, so you charge in dollars and receive dollars — clean, predictable, and stable.

**Global by Default**\
Runs across **Sui** network. Every payment produces a verifiable on-chain receipt compliant with the x402 standard.

**One-Line Integration**\
Import the SDK, call `pay()`, or drop the `<BeepPayButton />` component. Works anywhere you can run JavaScript — web, node, or agent runtime.

**Always Funded Accounts**\
Users pay from their Beep Vaults, Sui Wallets, or any USDC-compatible account. Agents can also pay autonomously via delegated session keys.

**No Extra Fees**\
Merchants receive the full amount. Beep’s yield-share mechanism offsets gas costs, keeping effective payment fees at zero.
