How to estimate the gas price

Step 1: Setup Moralis​

Read the article Setting Up Moralis: Getting Started and make sure to finish all the steps. Only after that you can go ahead to complete this guide.

Step 2: Estimate gas price​

In order to estimate the gas price, Moralis provides you a estimateGasPrice endpoint to do so.

Here you'll need one parameter: network.

Once you have obtained the network, you can copy the following code:

const Moralis = require("moralis").default;

const runApp = async () => {
await Moralis.start({
apiKey: "YOUR_API_KEY",
// ...and any other configuration
});

const network = "mainnet";

const response = await Moralis.AptosApi.transactions.estimateGasPrice({
network,
});

console.log(response);
};

runApp();

Step 3: Run the script​

To run the script, enter the following command:

node index.js

In your terminal, you should see the following JSON response:

{
"deprioritized_gas_estimate": 100,
"gas_estimate": 100,
"prioritized_gas_estimate": 150,
"__headers": {
"date": "Wed, 12 Apr 2023 15:09:16 GMT",
"content-type": "application/json",
"content-length": "84",
"connection": "close",
"x-aptos-chain-id": "1",
"x-aptos-ledger-version": "119821921",
"x-aptos-ledger-oldest-version": "0",
"x-aptos-ledger-timestampusec": "1681312155079381",
"x-aptos-epoch": "2186",
"x-aptos-block-height": "46554718",
"x-aptos-oldest-block-height": "0"
}
}

Congratulations πŸ₯³ You just estimate the gas price with just a few lines of code using the Moralis Transaction API!
