Palm quickstart

This quickstart guide will help you set up and make calls on the Palm network using the Infura endpoints.

Prerequisites​

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

Make calls​

curl​

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

curl https://palm-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://palm-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://palm-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

Ethers​

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

    npm install ethers

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

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

    index.js
    const ethers = require("ethers")

    const provider = new ethers.providers.JsonRpcProvider(
      "https://palm-mainnet.infura.io/v3/<YOUR-API-KEY>"
    )

    provider
      .getBlockNumber()
      .then((blockNumber) => {
        console.log(blockNumber)
      })
      .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://palm-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
