# Introduction

> Nuvion is a global banking infrastructure platform. Use our APIs to issue accounts, move money, accept payments, and offer FX to your users — anywhere in the world.

Nuvion gives platforms and marketplaces the financial infrastructure to operate globally. Through a single API integration, you can issue multi-currency accounts for your entities, accept payments across dozens of rails, send funds to any country, and enable stablecoin transactions — without building relationships with banks, payment networks, or liquidity providers yourself.

## How Nuvion works

Nuvion sits between your platform and the global financial system.

You integrate the Nuvion API once. We handle the bank relationships, payment network connectivity, compliance infrastructure, and liquidity — so your team focuses on your product.

```
Your Platform
    │
    ▼
Nuvion API
    │
    ├── Accounts & Balances
    ├── Payment Rails (bank, card, local methods)
    ├── Payout Networks (wire, local, real-time)
    ├── Stablecoin Networks
    └── FX & Currency Conversion
```

Your entities interact with financial products through your platform. Nuvion never surfaces directly to them.

## Core concepts

Before making your first API call, familiarize yourself with these building blocks:

<CardGroup cols={2}>
  <Card title="Entities" icon="user" href="/core-concepts/entities">
    The individuals or businesses your platform serves. Entities own accounts and initiate transactions.
  </Card>

  <Card title="Accounts" icon="wallet" href="/core-concepts/accounts">
    Multi-currency containers that hold balances. An entity can have multiple accounts across different currencies.
  </Card>

  <Card title="Webhooks" icon="webhook" href="/webhooks/overview">
    Real-time event notifications for payment settlements, account status changes, and transaction updates.
  </Card>
</CardGroup>
