Prerequisites

Ensure you have an API key with the HyperEVM network enabled.

Make calls

curl

Run the following command in your terminal, replacing <YOUR-API-KEY> with your actual Infura API key:

curl https://hyperevm-mainnet.infura.io/v3/<YOUR-API-KEY> \
  -X POST \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc": "2.0", "method": "eth_blockNumber", "params": [], "id": 1}'

Node (JavaScript)

In these examples, you'll use npm as your package manager.

Node Fetch

1. In your project folder, install the node-fetch package using npm:

   npm i node-fetch

2. Create your JavaScript file and copy the following code:

   Replace <YOUR-API-KEY> with your actual Infura API key.

   index.js

   import fetch from "node-fetch"
   
   fetch("https://hyperevm-mainnet.infura.io/v3/<YOUR-API-KEY>", {
     method: "POST",
     headers: {
       "Content-Type": "application/json",
     },
     body: JSON.stringify({
       jsonrpc: "2.0",
       method: "eth_blockNumber",
       params: [],
       id: 1,
     }),
   })
     .then((response) => response.json())
     .then((data) => {
       console.log(data)
     })
     .catch((error) => {
       console.error(error)
     })

3. Run the code using the following command:

   node index.js

Axios

1. In your project folder, install the axios package using npm:

   npm i axios

2. Create your JavaScript file and copy the following code:

   Replace <YOUR-API-KEY> with your actual Infura API key.

   index.js

   const axios = require("axios")
   
   axios
     .post("https://hyperevm-mainnet.infura.io/v3/<YOUR-API-KEY>", {
       jsonrpc: "2.0",
       method: "eth_blockNumber",
       params: [],
       id: 1,
     })
     .then((response) => {
       console.log(response.data)
     })
     .catch((error) => {
       console.error(error)
     })

3. Run the code using the following command:

   node index.js

Python

1. In your project folder, install the requests library:

   pip install requests

2. Create your Python file and copy the following code:

   Replace <YOUR-API-KEY> with your actual Infura API key.

   index.py

   import requests
   import json
   
   url = "https://hyperevm-mainnet.infura.io/v3/<YOUR-API-KEY>"
   
   payload = {
     "jsonrpc": "2.0",
     "method": "eth_blockNumber",
     "params": [],
     "id": 1
   }
   
   headers = {"content-type": "application/json"}
   
   response = requests.post(url, data=json.dumps(payload), headers=headers).json()
   
   print(response)

3. Run the code using the following command:

   python index.py

Next steps

Now that you have successfully made a call to HyperEVM mainnet, you can explore more JSON-RPC methods in the HyperEVM JSON-RPC API documentation.
