| Chain ID | Name         | Notes                                      |
|----------|--------------|--------------------------------------------|
| 1        | Ethereum     | Mainnet, widely used for Uniswap trades   |

### Tools and Prompts

#### 1. `getPrice`
Fetches a price quote for a Uniswap swap.

**Schema**:
- `chainId`: Number (default: 1)
- `tokenIn`: String (e.g., `"NATIVE"` or token address)
- `tokenOut`: String (e.g., `"NATIVE"` or token address)
- `amountIn`: String (optional, required for `"exactIn"`)
- `amountOut`: String (optional, required for `"exactOut"`)
- `tradeType`: `"exactIn"` or `"exactOut"` (default: `"exactIn"`)

Example prompt:

```
