JSON-RPC methods

Example RPC

curl https://api.chainup.net/ethereum/mainnet/<YOUR_API_KEY> \
-X POST \
-H 'content-type: application/json' \
-H "CONSISTENT-HASH: true" \
--data '{"jsonrpc":"2.0","method":"net_peerCount","params":[],"id":1}' 
const axios = require('axios'); 
//npm install axios if you don have the module installed

let options = {
    url: "https://api.chainup.net/ethereum/mainnet/<YOUR_API_KEY>",
    method: "post",
    headers: {
        "content-type": "application/json",
        "CONSISTENT-HASH": "true"  // Add your custom header here
    },
    data: {"jsonrpc":"2.0","method":"net_peerCount","params":[],"id":1}
};

axios(options)
    .then(response => {
        console.log('Post successful: response:', response.data);
    })
    .catch(error => {
        console.error('An error has occurred:', error);
    });

Due to the computational resources consumed by certain RPCs, the free public RPC only supports the RPCs mentioned above. The rest of the JSON-RPCs will be intercepted and return a 403 status code.
