### Query Swap Rates with Aggregator API (JavaScript)

Source: https://docs.kyberswap.com/kyberswap-solutions

This JavaScript example demonstrates how to query the KyberSwap Aggregator API to get superior swap rates. It involves making an HTTP GET request to the API endpoint with relevant parameters such as token addresses and amounts.

```javascript
async function getSwapRates(tokenIn, tokenOut, amountIn) {
  const apiUrl = 'https://aggregator-api.kyberswap.com/routes/simulate';
  const params = {
    tokenIn: tokenIn, // e.g., '0x0000000000000000000000000000000000000001' for native token
    tokenOut: tokenOut, // e.g., '0x...'
    amountIn: amountIn.toString(),
    source: 'KyberSwap'
  };

  const url = `${apiUrl}?${new URLSearchParams(params).toString()}`;

  try {
    const response = await fetch(url);
    if (!response.ok) {
      throw new Error(`HTTP error! status: ${response.status}`);
    }
    const data = await response.json();
    return data.data.bestRoute;
  } catch (error) {
    console.error('Error fetching swap rates:', error);
    return null;
  }
}

// Example usage:
// const tokenInAddress = '0x...'; // Address of input token
// const tokenOutAddress = '0x...'; // Address of output token
// const amount = 1000000000000000000; // 1 token in Wei

// getSwapRates(tokenInAddress, tokenOutAddress, amount).then(route => {
//   if (route) {
//     console.log('Best route:', route);

        uint amountOutMin,
        address[] calldata path,
        address to,
        uint deadline,
        PermitTransferFrom calldata permit

}

contract PermitSwapExample {
    IKyberSwapAggregatorRouter public immutable router;

    constructor(address _routerAddress) {
        router = IKyberSwapAggregatorRouter(_routerAddress);
    }

    function performSwapWithPermit(

### Get Maker Orders (TypeScript)

Source: https://docs.kyberswap.com/kyberswap-solutions/limit-order/developer-guides/gasless-cancel

Retrieves a list of active or open limit orders for a Maker address using the `/read-ks/api/v1/orders` endpoint. This is the first step in identifying orders to be cancelled. It requires chain ID, maker address, and order status as parameters.

```typescript
const targetPathConfig = {
    params: {

        maker: signerAddress,
        status: "active"
    }
};

```

--------------------------------

### Filter and Get Target Order ID (TypeScript)

Source: https://docs.kyberswap.com/kyberswap-solutions/limit-order/developer-guides/gasless-cancel

Filters the list of Maker orders obtained from the `/read-ks/api/v1/orders` endpoint to find a specific order based on maker address, maker asset, and taker asset. It then extracts the `orderId` of the target order for cancellation. This step assumes the `getOrders` function has already fetched the orders.

```typescript
const orders = await getOrders();
const targetOrder = orders.filter(order => 
    order.maker.toLowerCase() == signerAddress.toLowerCase() &&
    order.makerAsset.toLowerCase() == makerAsset.address.toLowerCase() &&
    order.takerAsset.toLowerCase() == takerAsset.address.toLowerCase()
);
const targetOrderId = Number(targetOrder[0].id);

```
