+# Ethereum Classic Transaction Broadcast with Node.js
+
+This documentation provides a guide to broadcast Ethereum Classic transactions to the mainnet using a Node.js script and the CryptoAPIs service.
+
+## Requirements
+
+- Node.js installed on your machine
+- [Axios'](https://www.npmjs.com/package/axios) library for making HTTP requests
+
+## Setup
+
+1. Install the required package by running:
+
+   ```bash
+   npm install axios
+
+2. Obtain an API Key from CryptoAPIs:
+   - Sign up for [cryptoapis.io](https://my.cryptoapis.io/login)
+   - Create a new api-key [here](https://my.cryptoapis.io/api-keys)
+
+## Script 
+Create a new file called `broadcastETCTransaction.js` 
+and add the following script:
+
+```js
+const axios = require('axios');
+
+// Replace with your API key
+const apiKey = 'your-api-key-here';
+
+// Replace with your signed transaction hex
+const signedTransactionHex = 'your-signed-transaction-hex-here';
+
+const broadcastTransaction = async () => {
+  try {
+    const response = await axios.post(
+      'https://rest.cryptoapis.io/blockchain-tools/ethereum-classic/mainnet/transactions/broadcast?context=broadcastETC',
+      {
+        context: '', // Optional
+        data: {
+          item: {
+            signedTransactionHex: signedTransactionHex
+          }
+        }
+      },
+      {
+        headers: {
+          'x-api-key': apiKey,
+          'Content-Type': 'application/json'
+        }
+      }
+    );
+
+    console.log('Transaction Broadcasted Successfully:', response.data);
+  } catch (error) {
+    console.error('Error broadcasting transaction:', error.response ? error.response.data : error.message);
+  }
+};
+
+broadcastTransaction();
+
+```
+
+## Running the script
+1. Replace the `apiKey` and `signedTransactionHex` variables with your actual API key and signed transaction hex.
+2. Run the script:
+  ```
+  node broadcastETCTransaction.js
+  ```
+
+## Response
+
+If successful, the script will output a JSON object with the following structure:
+```json
+{
+  "apiVersion": "string",
+  "requestId": "string",
+  "context": "string",
+  "data": {
+    "item": {
+      "transactionId": "string"
+    }
+  }
+}
+```
+The response will contain the following fields:
+
+- `apiVersion` (string): The version of the API.
+
+- `requestId` (string): The ID of the request.
+
+- `context` (string): The context of the response.
+
+- `data` (object):
+
+  - `item` (object):
+
+    - `transactionId` (string): The ID of the broadcasted transaction.
