## Usage

  ```tsx code
  import { fetchOnrampConfig } from '@coinbase/onchainkit/fund';

  // When using with OnchainKitProvider
  const config = await fetchOnrampConfig();

  // When using without OnchainKitProvider or in non-React environment
  const config2 = await fetchOnrampConfig('your-api-key');
  ```

  ```js return value
  {
    countries: [
      {
        id: "US",
        subdivisions: ["CA", "NY", "TX"],
        paymentMethods: [
          {
            id: "CARD",
            name: "Credit or debit card",
            description: "Pay with Visa or Mastercard",
            currencies: ["USD", "EUR"],
            minAmount: { value: "10.00", currency: "USD" },
            maxAmount: { value: "1000.00", currency: "USD" }
          }
        ]
      }
    ]
  }
  ```
