# QuickStart guide

1. Sign Up: [Request an API key](https://www.unizen.io/developer). Choose the plan or contact us to discuss about your needs.
2. Fetch a Single-Chain Swap Quote: just a simple call to our api passing the api key as header.

```bash
curl -X 'GET' \
  'https://api.zcx.com/trade/v1/56/quote/single?fromTokenAddress=0x0000000000000000000000000000000000000000&toTokenAddress=0x55d398326f99059ff775485246999027b3197955&amount=10000000000000000000&sender=0x54c47034887C582Fc1Af4a9a3b68180a8a9eF2d2&receiver=0x54c47034887C582Fc1Af4a9a3b68180a8a9eF2d2&slippage=0.005&excludedDexes=%7B%0A%20%20%221%22%3A%20%5B%0A%20%20%20%20%220x0000000000000%22%0A%20%20%5D%0A%7D&priceImpactProtectionPercentage=0.5&slippageProtectionPercentage=0.5' \
  -H 'accept: application/json' \
  -H 'Authorization: Bearer <YOUR API KEY>'
```

3. The response is an array of quotes, choose the desired quote (the first is the best in terms of amount out) and take the transactionData and just a few fields and call the swap endpoint.

```bash
curl -X 'POST' \
  'https://api.zcx.com/trade/v1/56/swap/single' \
  -H 'accept: application/json' \
  -H 'Authorization: Bearer <YOUR API KEY>' \
  -H 'Content-Type: application/json' \
  -d '{

4. Finally in the response of this swap endpoint you have the data to conduct the trade on the user's wallet.
