验证

1inch 开发者门户 API 使用 API 密钥来验证请求。您可以在仪表板和应用程序菜单中查看您的 API 密钥。

您的 API 密钥具有许多权限，因此请务必保证它们的安全！请勿在可公开访问的区域（例如 GitHub、客户端代码等）共享您的秘密 API 密钥。

API 的身份验证是通过 API 密钥执行的。提供您的 API 密钥作为 Authorization: Bearer 标头：

curl -X 'GET' \
  'https://api.1inch.dev/swap/v5.2/1/tokens' \
  -H 'accept: application/json' \
  -H 'Authorization: Bearer YOUR-API-KEY'

如何使用 1inch Swap API

第 2 步：设置您的环境

const Web3 = require("web3");
const fetch = require("node-fetch");
const yesno = require("yesno");

const chainId = 56; // Chain ID for Binance Smart Chain (BSC)
const web3RpcUrl = "https://bsc-dataseed.binance.org"; // URL for BSC node
const walletAddress = "0x...xxx"; // Your wallet address
const privateKey = "0x...xxx"; // Your wallet's private key. NEVER SHARE THIS WITH ANYONE!

第 3 步：定义交换参数

const swapParams = {
  src: "0x111111111117dc0aa78b770fa6a738034120c302", // Token address of 1INCH
  dst: "0x1af3f329e8be154074d8769d1ffa4ee058b1dbc3", // Token address of DAI
  amount: "100000000000000000", // Amount of 1INCH to swap (in wei)
  from: walletAddress,
  slippage: 1, // Maximum acceptable slippage percentage for the swap (e.g., 1 for 1%)
  disableEstimate: false, // Set to true to disable estimation of swap details
  allowPartialFill: false // Set to true to allow partial filling of the swap order
};

第 4 步：定义 API URL、您的 API 密钥并初始化 Web3 库

const broadcastApiUrl = "https://api.1inch.dev/tx-gateway/v1.1/" + chainId + "/broadcast";
const apiBaseUrl = "https://api.1inch.dev/swap/v6.0/" + chainId;
const web3 = new Web3(web3RpcUrl);
const headers = { headers: { Authorization: "Bearer YOUR_API_KEY", accept: "application/json" } };

第 5 步：定义辅助函数

// Construct full API request URL
function apiRequestUrl(methodName, queryParams) {
  return apiBaseUrl + methodName + "?" + new URLSearchParams(queryParams).toString();
}

// Post raw transaction to the API and return transaction hash
async function broadCastRawTransaction(rawTransaction) {
  return fetch(broadcastApiUrl, {
    method: "post",
    body: JSON.stringify({ rawTransaction }),
    headers: { "Content-Type": "application/json", Authorization: "Bearer YOUR-API-KEY" }
  })
    .then((res) => res.json())
    .then((res) => {
      return res.transactionHash;
    });
}

// Sign and post a transaction, return its hash
async function signAndSendTransaction(transaction) {
  const { rawTransaction } = await web3.eth.accounts.signTransaction(transaction, privateKey);

  return await broadCastRawTransaction(rawTransaction);
}

第 6 步：检查代币限额

const allowance = await checkAllowance(swapParams.src, walletAddress);
console.log("Allowance: ", allowance);
