LIBRARY RULES
===============
From library maintainers:
- All amount fields (sellAmount, buyAmount, fees) are BigInt, not number or string. API transmits hex strings but SDK exposes BigInt.
- Use getBaseUrl() for swap/dca/token/staking services. Use getImpulseBaseUrl() for market data (impulse) service.
- Actions follow build/execute pattern: *ToCalls() returns Call[], execute*() handles normal flow & paymaster support.
- Pagination uses Page<T> type with content, totalElements, totalPages, hasNext. Not simple arrays.
- Paymaster integration uses InvokePaymasterParams with provider (PaymasterInterface from starknet), params (ExecutionParameters), and active boolean flag.

### Get Token Quotes and Execute Swap

Source: https://github.com/avnu-labs/avnu-sdk/blob/develop/README.md

Use getQuotes to fetch swap quotes and executeSwap to perform the token exchange. Requires sell token, buy token, sell amount, and taker address. Ensure slippage is set.

```typescript
import { getQuotes, executeSwap } from '@avnu/avnu-sdk';

const quotes = await getQuotes({
  sellTokenAddress: '0x...',
  buyTokenAddress: '0x...',
  sellAmount: 1000000n,
  takerAddress: account.address,
});

await executeSwap({
  quote: quotes[0],
  slippage: 0.01, // 1%
  account,
});
```
