## Response

<ResponseField name="base_fee" type="integer" required>
  Base fee rate in basis points. For example, a value of 200 represents a 2% fee (200 basis points).
</ResponseField>

### Response Example

```json

## Understanding Fee Rates

Fee rates are expressed in basis points (bps):
- **1 basis point** = 0.01% = 0.0001
- **100 basis points** = 1%
- **200 basis points** = 2%

### Example Calculation

For a trade of 1000 USDC with a base_fee of 200 bps:
```bash
Fee = 1000 × (200 / 10000) = 1000 × 0.02 = 20 USDC
```bash
