# Get Quote

This endpoint will return currently available routes with estimated target token amount for your quote. You can also designate specific bridges or aggregator to customize the route. If there is no available route, it will return an error\_code, which you can reference [here](/bridge-aggregator-integration/xy-finance-api-multiple-bridges-aggregator/error-message.md) to get error detail.

### Parameter/Response Details

* Use `0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE` as the address for the native token in your parameter.
* If you would like to know more about **commissionRate** fields and fee collection function, please refer to [Monetization / Take Fees](/bridge-aggregator-integration/xy-finance-api-multiple-bridges-aggregator/monetization-take-fees.md)
* If you would like to know latest supported bridge provider and swap provider, please refer to [Supported Blockchains/Bridges/DEXs](/bridge-aggregator-integration/xy-finance-api-multiple-bridges-aggregator/supported-blockchains-bridges-dexs.md)
* The `estimatedGas` field in the API response is an estimated value. For now, please use a method similar to RPC, such as [eth\_estimateGas](https://www.quicknode.com/docs/ethereum/eth_estimateGas), to re-estimate the actual gas limit. You can refer to the following sample code to do that:

```python
from web3 import Web3
import requests
​
if __name__ == "__main__":
    # 1st: get tx data from xy aggregator api
    endpoint = 'https://aggregator-api.xy.finance/v1/buildTx?srcChainId=137&srcQuoteTokenAddress=0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE&srcQuoteTokenAmount=9000000000000000000&dstChainId=56&dstQuoteTokenAddress=0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d&slippage=1&receiver=0x9cEEEbdF49cF5DEa891C9D74f8ea03af2aCf284F&bridgeProvider=yBridge&srcBridgeTokenAddress=0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174&dstBridgeTokenAddress=0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d&srcSwapProvider=OneInch%20V4%20DexAggregator&affiliate=0x512E00f66217714BAee5F0736428b026e8c30AF5'
    resp = requests.get(endpoint)
    resp_json = resp.json()
​
    # 2nd: get estimateGas by calling web3 rpc
    rpc_endpoint = 'https://polygon.llamarpc.com'
    w3 = Web3(Web3.HTTPProvider(rpc_endpoint))
    estimate_gas = w3.eth.estimate_gas(resp_json["tx"])
​
    # 3rd: Combine the estimateGas with the tx data
    tx = resp_json["tx"]
    tx["gas"] = estimate_gas
​
    # 4th: sign the tx & send it
    priv_key = "0x"
    tx_signed = w3.eth.account.sign_transaction(tx, priv_key)
    tx_hash = w3.eth.send_raw_transaction(tx_signed.rawTransaction)
```

### Example Request

```shell
$ curl "https://aggregator-api.xy.finance/v1/quote?srcChainId=10&srcQuoteTokenAddress=0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE&srcQuoteTokenAmount=1000000000000000000&dstChainId=56&dstQuoteTokenAddress=0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE&slippage=1&bridgeProviders=yBridge
```

This request is asking a quote of **1 ETH** on **Optimism** to **ETH** on **Arbitrum Chain** and designate yBridge as bridgeProvider.

{% hint style="warning" %}
**`IMPORTANT:`**` ``Note that the amount parameter should be padded with zeroes. For example, pass`` `**`100000000`**` ``instead of`` `**`100`**` ``if the decimals of the token is 6.`
